Abstract

OBJECTIVE: To compare the effectiveness of diabetes prevention strategies addressing postpartum weight retention for women with gestational diabetes mellitus (GDM) delivered at the health system level: mailed recommendations (usual care) versus usual care plus a Diabetes Prevention Program (DPP)–derived lifestyle intervention. RESEARCH DESIGN AND METHODS: This study was a cluster randomized controlled trial of 44 medical facilities (including 2,280 women with GDM) randomized to intervention or usual care. The intervention included mailed gestational weight gain recommendations plus 13 telephone sessions between 6 weeks and 6 months postpartum. Primary outcomes included the following: proportion meeting the postpartum goals of 1) reaching pregravid weight if pregravid BMI <25.0 kg/m2 or 2) losing 5% of pregravid weight if BMI ≥25.0 kg/m2; and pregravid to postpartum weight change. RESULTS: On average, over the 12-month postpartum period, women in the intervention had significantly higher odds of meeting weight goals than women in usual care (odds ratio [OR] 1.28 [95% CI 1.10, 1.47]). The proportion meeting weight goals was significantly higher in the intervention than usual care at 6 weeks (25.5 vs. 22.4%; OR 1.17 [1.01, 1.36]) and 6 months (30.6 vs. 23.9%; OR 1.45 [1.14, 1.83]). Condition differences were reduced at 12 months (33.0 vs. 28.0%; OR 1.25 [0.96, 1.62]). At 6 months, women in the intervention retained significantly less weight than women in usual care (mean 0.39 kg [SD 5.5] vs. 0.95 kg [5.5]; mean condition difference −0.64 kg [95% CI −1.13, −0.14]) and had greater increases in vigorous-intensity physical activity (mean condition difference 15.4 min/week [4.9, 25.8]). CONCLUSIONS: A DPP-derived lifestyle intervention modestly reduced postpartum weight retention and increased vigorous-intensity physical activity.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Of 5 TM studies on T2DM development, 1 by Sakane et al indicated TM is effective, and the other 4 did not show significant differences compared to the control group.

    “Of the 5 (20%) studies reporting the effects of TM on T2DM development, only 1 (20%) study by Sakane et al [39] indicated that TM is effective. The other 4 (80%) studies [35,40,44,50] did not show any significant differences compared to the control group.”

    From Digital Health Interventions to Prevent Type 2 Diabetes Mellitus: Systematic Review (2025) · cites this paper as [50]

    The Exploratory Outcomes section reports no statistically significant difference between intervention and usual care for *combined prediabetes or diabetes* incidence (hazard ratio 0.90, 95% CI 0.78–1.04). It does not report a separate significance test for type 2 diabetes development, so it supports the cited sentence only at the broader combined-outcome level. The paper does not assess the sentence’s count of five studies or its claim about Sakane et al. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
