Stored-material review date: Not recorded  
Original evidence cut-off: 2026-09-08  
Review-criteria version: 1.0  
Public page/material preparation date: 2026-10-23

Clinical papers were not read directly; existing review summaries were checked. No new clinical-literature search was performed. Unverified does not mean that research is absent or that there is no effect.

## Assessment scope

- Population: The population is women with rheumatoid arthritis who continued stable antirheumatic medication. Detailed diagnosis, age, baseline DAS28, severity, comorbidities and inclusion/exclusion criteria remain unverified. Applicability to men, osteoarthritis or every disease stage is not assumed.
- Ingredient, formulation and route: The question concerns oral adjunctive fixed seed-oil capsules prepared by a manufacturer. Detailed product, batch, content, active-constituent and quality information remains unverified. Seed powder, extracts, topical preparations, purified thymoquinone and combinations are not treated as interchangeable.
- Dose: The original record of 500 mg, 2 times daily, with an original total of 1 g/day is retained. Actual use, adherence, discontinuation and active-constituent exposure remain unverified. No new active-dose conversion, cumulative dose, optimal dose or individual dosing guidance is created.
- Comparator: A comparison adding starch placebo to common antirheumatic treatment is kept distinct from the fixed sequence in which everyone received placebo followed by seed oil. Details of maintained/changed medication, rescue treatment, placebo composition and masking remain unverified.
- Measured outcome: The selected question concerns DAS28 disease activity and joint symptoms. Detailed scale components, version, assessor, baseline adjustment, change scores, prospective hierarchy and response or remission criteria remain unverified. Immune, inflammatory and oxidative-stress markers are not converted into independent clinical replications.
- Duration: The original 1–2-month range is retained. R01 used a fixed sequence of placebo for 1 month followed by seed oil for 1 month; the R02 result is after 2 months. Exposure periods and assessment times are not merged into the same comparison, and persistence after discontinuation or long-term effects remains unverified.
- Questions outside this scope: The question concerns adjunctive seed oil in women continuing stable DMARD and steroid treatment. It is not extended to established replacement/discontinuation of antirheumatic drugs, prevention of structural damage, cure or other joint diseases.; The existing C·50 points·Caution, B/P/R1/I1/E+/B2/C0 and evidence date 2026-09-08 are retained. Historical cross-checking wording and assessment do not establish new independent clinical validation or completed review here.; The R01 record of 40 women and DAS28 4.99±0.72 after placebo versus 4.55±0.82 after oil, P=.017 is retained. Randomized period allocation is not recorded, and these period-specific values are not used to calculate a new concurrent between-group difference, change score or CI.; The R02 report of between-group DAS28 improvement after 2 months and the absence of an exact adjusted CI are retained within the stored-summary scope. No completion denominator is selected from 39·42·43 people, averaged or pooled, and R01 numbers are not transferred to fill gaps.; Reports on hs-CRP, TNF, IL-10 and oxidative stress are distinguished as additional reports from the same parallel cohort. Report counts are not converted into totals of unique trials, independent teams or participants; unestablished totals remain unverified.; Limited funding information for R01 remains separate from Tabriz University support, Barij employee authorship and product preparation for R02. University support, product provision, employment and declared conflicts do not substitute for one another, and no new independence judgment is made here.; The English-placeholder correction date 2026-09-14 for 2 fields and the original evidence date are retained. Material-specific production-reading records for stored summaries remain distinct from unread external material and unrecorded dates; historical generic verification wording is not promoted into current verification.; Short-term seed-oil material in women does not certify long-term, rare or vulnerable-group harms or overall safety. Original caution about product differences, pregnancy/breastfeeding, children, liver/kidney disease, surgery and concomitant medicines remains; no new harm rate, causality or contraindication is created.

- Materials to obtain first: Original funding, author, product-contract and trial-family links are needed. No new score or count of independent teams is created here.
- Further research: Material needed: Original funding, author, product-contract and trial-family links are needed. No new score or count of independent teams is created here. This records needed materials; no new research was executed.
- Conditions for verification: Original records on The original I1/rationale and the present preserved-material scope must link to the relevant report, design, formulation, background treatment, endpoint, timing and denominator, distinguishing recorded information from what remains unverified.
- Why this condition is needed: Material on The original I1/rationale and the present preserved-material scope is needed to connect adjunctive seed oil to its population, formulation, concomitant treatment, comparison, outcome, timing, denominator or harms.
- Application exceptions: A fixed-sequence comparison is not converted into randomized period allocation or a concurrent parallel control. Mechanistic papers from the same cohort are not counted as independent clinical replications; inconsistent denominators are not selected or pooled, and no new differences, intervals, harm rates or doses are calculated.
- Remaining uncertainty: Gaps in product details, background treatment, period order, scale, report-specific denominators, dispersion, prospective plans, company roles and harms remain. Favorable directions are not converted into the same comparative effect, independent replication, cure or long-term safety.
- Referenced methods: Existing principles distinguish the population, formulation, background treatment, comparative design, DAS28, timing, denominators, related reports, company involvement and harms of adjunctive seed oil.

## What the statuses mean

- Partly verified: Partial information from the stored summary is linked; detailed originals and content review remain incomplete.
- Unverified: Required details cannot be established within the preserved scope. This does not establish absence of effects or studies, or safety.
- Review incomplete: Review of existing content remains incomplete.
- Met: This state is used only within the relevant conditions after material verification and content review. It was not automatically assigned in this work.
- Not reported: Unreported within material actually read. Unread external material is not relabeled as unreported.
- Inaccessible: This means actual access failure. External access was not attempted in this work, so this state was not assigned.
- Not applicable: Used only with an application exception and reason based on the question scope.
- Conflicting data: This requires actual comparison of materials; no new conflict judgment was made in this work.
- Insufficient evidence for the conditions: This indicates gaps in additional material for the selected conditions. Unread material as a whole is not converted into an efficacy grade.
