Assessment scope

Stored-material review date: Not recorded
Original evidence cut-off: 2026-08-26
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: 351 adults aged 21–65 with obesity at US community health centers, with at least one of hypertension, diabetes or hyperlipidemia. Original randomized denominators: 176 intervention/175 usual care. Detailed eligibility, baseline weight/conditions, visit-specific observations/analyses and attrition/missingness remain unverified.
Ingredient, formulation and route: Multicomponent Track: app-based goal self-monitoring, algorithm-tailored feedback, daily cellular smart-scale weighing, 18 dietitian calls and clinician counseling based on electronic-record recommendations. Stand-alone app/scale/counseling effects cannot be separated. Only the research composition is preserved; no implementation instructions or recommendations are created.
Dose: Only original planned elements such as 18 counseling calls and daily self-monitoring, and the 12-month evaluation, are preserved. Actual component-specific delivery/use, cumulative contacts, adherence and discontinuation remain unverified; completion by all participants is not assumed.
Comparator: Parallel comparison with usual care. Actual control management, contact/support, use of other programs, concurrent medication/condition/lifestyle management and crossover use remain unverified. Usual care is not converted into no intervention or contact.

S01 · Bennett GG et al. 2018 Track

PubMed

Material type: Community-health-center randomized usual-care-controlled effectiveness trial
Materials actually read: Summary read; external material unread
Findings recorded in the stored summary: −4.0 kg versus −0.1 kg; between-group difference −3.8 kg (95% CI −5.0 to −2.5), P<0.001. At least 5% weight loss was 40% versus 17%, P<0.001, but this was a secondary responder criterion rather than the primary endpoint. Null trials of app-only or low-intensity technology support are also noted; this result is limited to the Track bundle including counseling.
Record level: Outcome wording in the stored summary
Study overlap and independent replication: S01 Bennett2018 Track is one 12-month parallel report comparing bundled Track with usual care in 351 adults (176/175) aged 21–65 with obesity and at least one of hypertension/diabetes/hyperlipidemia at US community health centers. Individual effects of the app, cellular smart scale, 18 dietitian calls and clinician counseling cannot be separated. The two sheets share the same people/report. Standardized research-visit mean changes of −4.0 kg (95% CI −4.9 to −3.0) versus −0.1 kg (−1.0 to 0.8), and between-group difference −3.8 kg (−5.0 to −2.5), P<0.001, are primary continuous results. At least 5% weight loss, 40% versus 17%, P<0.001, is a secondary responder result; proportions or event counts are not calculated from means. Registration, ITT/maximum likelihood, public funding and later author disclosures are preserved historical narratives, not current external reading/content review. Specific bibliographies for other low-intensity null trials and later disclosures are unlinked, so no new report is created. Groups, time points, thresholds, bibliography/registration and sibling sheets are not added as new independent trials or participants; report-item counts are not unique clinical totals.

What the statuses mean

Met: Status for necessary evidence confirmed after existing content review. No completion is declared in the current presentation.
Partly verified: Some information in the stored summary is linked into the table. External comparison/content review is not complete.
Unverified: The article leaves this unverified, or required material is absent from the current stored summary. This is distinct from zero, absence or safety.
Review incomplete: Existing content review remains incomplete.
Not reported: Not reported within the stored material actually read; not extended to the entire primary paper.
Inaccessible: Means an actual access failure. Access not attempted here is not assigned this state.
Not applicable: Not used as a substitute for an evidence gap.
Conflicting data: Requires an observed disagreement under the same comparison criteria; not automatically judged in this production.
Insufficient evidence for the conditions: Marks a gap in additional material required by the selected conditions; not a new efficacy grade.
