Assessment scope

Stored-material review date: Not recorded
Original evidence cut-off: 2026-09-07
Scope actually checked: Existing review summaries and stored records of methodological application. Full papers, supplements, registrations, plans and original data were not read.
What the dates mean: This is the date the stored materials were checked, not the date of a new search of the clinical literature.
Population: R01 Payton concerns epidural laboring women, with no recorded numeric sample size. R02 Alan Dikmen records 90 participants; R03 Ozkececi records high-BMI participants with 70 randomized/59 analyzed. Arm-specific eligibility, parity, BMI thresholds, anesthesia/analgesics, maternal/fetal status and duration-/operative-event denominators are unverified.
Ingredient, formulation and route: Distinguish round birth balls from peanut balls and ball-only use from positioning/pelvic-movement packages. The direct bibliographies concern peanut-ball reports. Ball specifications, components, supervision, actual use and accompanying labor management are unverified by report. Unidentified earlier combined programs are not turned into new trials and their signals are not assigned to a ball alone.
Dose: The parent descriptions of use timing, frequency and movements identify research context. R02 pain/fatigue after 15 minutes is a measurement time, not a duration-shortening effect or duration of ball use. Exact exposure and adherence are unverified; no new total exposure, repetition count or delivery method is calculated or recommended.
Comparator: The parent comparator label is standard care. Distinguish R01 epidural conditions from report-specific actual controls, analgesics, positioning, contact and obstetric management. A representative comparator is not applied to every report and does not establish an isolated ball or non-drug effect.
Measured outcome: The selected question concerns labor duration and cesarean prevention. Distinguish R01 first-stage primiparous interaction P=.018, multiparous P=.057 and null pushing time; R02 total labor duration P=.177; and R03 active-labor duration 202.9±59.5 versus 213.6±67.5 minutes/P=.522. R03 pain P=.001 is separate from unverified co-primary success rules and arm-specific cesarean events/effects/CIs.
Duration: Distinguish total labor, active labor, first-stage and pushing intervals within the index labor. Their starts, ends and time origins, operative-event timing, recovery, subsequent delivery and long-term maternal/neonatal follow-up are unverified. Short pain/duration signals do not establish sustained benefit or safety.
Questions outside this scope: Transferring positive pain/fatigue into shorter total labor, fewer cesarean/instrumental deliveries or less analgesic use; Extending a primiparous interaction into the same benefit for all women, multiparous participants or every labor stage; Transferring vaginal delivery among completers into operative prevention for all randomized participants; Combining ball/movement packages, anesthesia, controls or time intervals as the same intervention/endpoint; Substituting null P values for zero effect/equivalence, ± for CIs, or positive pain for joint success; Summing randomized/analyzed populations, subgroups, both sheets or reports into new participant, unique-trial or independent-replication totals; Creating new effects, CIs, attrition counts/rates, grades, independence/safety certification or labor-ball, delivery or treatment instructions

Conditions for verification: Material for Harm definitions, collection, comparators and exposure denominators must be linked to the selected subclaim, parent context, same report/trial, outcome units, times, actual comparator and denominators, distinguishing unread external material.
Why this condition is needed: This condition connects Harm definitions, collection, controls and exposure denominators with labor duration and cesarean prevention, time intervals, subgroups, event denominators, ball and movement components, anesthesia, controls, co-primary outcomes, support and harms.
Application exceptions: Preserve selected subclaim D and its note that overall duration and operative events were not consistently established. Distinguish absent subclaim score, status and axes from parent pain C50. Positive pain, a primiparous interaction and vaginal delivery among completers do not establish shorter overall labor or cesarean prevention. Create no new effects, CIs, attrition counts/rates, totals, grades, independence/safety certification or labor-ball, delivery or treatment instructions.
Referenced methods: Preserved C/E/H application conditions concerning questions, populations, interventions, comparators, reports versus studies, endpoints, denominators and harms were referenced.

N26 · Are long-term/rare harms and post-intervention outcomes available?

Current findings: Brief pain/duration data during the index labor do not establish rare maternal/fetal harms, long-term recovery or subsequent-delivery outcomes.
Verification status: Unverified
Materials actually read: Stored summary read; external abstracts, full texts, registration, protocols, SAPs and support disclosures unread
Why unverified: The selected claim, parent material and reports are distinguished and transferred from the stored summary. Detailed original material is unverified and review of existing content remains incomplete. This does not establish completed clinical review or certification.
Reason for missing information: Actual long-term/harm follow-up, exposure duration, endpoint denominators and report linkage. Unread/unverified material does not mean 0 events or safety.
Required materials and conditions: Direct follow-up of long-term and rare harms
Materials to obtain first: Actual long-term/harm follow-up, exposure duration, endpoint denominators and report linkage. Unread/unverified material does not mean 0 events or safety.
Further research: Material needed: Actual long-term/harm follow-up, exposure duration, endpoint denominators and report linkage. Unread/unverified material does not mean 0 events or safety. This records needed materials; no new research was executed.

N27 · Which new materials would prompt an update to this table?

Current findings: This is a production sheet of preserved labor-duration/cesarean material. Relevant rows and links can be updated after reviewing originals, endpoints/timing, denominators, actual controls, shared reports and support/harm material.
Verification status: Partly verified
Materials actually read: Stored summary read; external abstracts, full texts, registration, protocols, SAPs and support disclosures unread
Why unverified: The selected claim, parent material and reports are distinguished and transferred from the stored summary. Detailed original material is unverified and review of existing content remains incomplete. This does not establish completed clinical review or certification.
Reason for missing information: Complete prior originals, new material, condition versions, separate application and review records. Material additions, condition revisions and verdict changes remain separate events.
Required materials and conditions: Changes in material, conditions, observations and verdicts
Materials to obtain first: Complete prior originals, new material, condition versions, separate application and review records. Material additions, condition revisions and verdict changes remain separate events.
