The mediating role of social support in behavioral changes and weight loss outcomes among overweight Appalachian adults.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Social support plays a key role in behavioral changes, especially in Appalachian populations. We examined the mediating effect of social support in behavioral changes and corresponding weight loss outcomes among Appalachian adults. Data were from a group-randomized trial that compared a 12-month faith-based weight loss intervention to an active control group among overweight Appalachian adults in churches. Participants from the weight loss intervention who completed the 12-month assessment were the focus of this analysis. Baseline and 12-month data on weight, social support for eating habits (SSEH) and physical activity (SSPA) from family, friends, and church family, physical activity, and dietary intake were collected. Logistic and linear regression models evaluated mediating effects of SSEH and SSPA on the association between intervention attendance and behavioral changes and corresponding weight loss outcomes. Most participants (n = 243) were female (76.2%), white (97.5%), and married or living with a partner (81.2%). After the 12-month intervention, participants lost weight (1.1 ± 0.3 kg), increased fruit and vegetable intake (0.4 ± 0.1servings/day), reduced caloric intake (322.9 ± 42.2 kcal/day), improved SSEH from family, and increased SSPA from the church family (all P < 0.05). Increased SSEH from family mediated 62% of the association between intervention attendance and fruit and vegetable servings per day. Each 100 kcal decrease in caloric intake was associated with decreased weight and BMI at 12-months (0.2 ± 0.1 kg, P = 0.003; 0.1 ± 0.02 kg/m
