Weight loss maintenance among truck drivers in the SHIFT randomised controlled trial, USA.
Trial report in Occupational and environmental medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02105571 (Social Support During a Randomized Trial of a Trucker Weight Loss Intervention), which is not on this map. Cited by 1 paper, 1 of them a synthesis that pooled it.
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.

Abstract
objectiveTo evaluate weight loss maintenance among truck drivers following an effective initial intervention and to test a priori hypotheses that social support and stress factors would moderate long-term success.
methodsCommercial truck drivers enrolled in the Safety & Health Involvement For Truckers cluster-randomised controlled trial (22 terminal clusters; n=452) completed measurements at baseline, postintervention (6 months) and 1 year postintervention (18 months) in the USA in 2012-2015. The mobile health intervention was a group-based competition involving self-monitoring, feedback, incentives, online training and motivational interviewing.
resultsIn an intent-to-treat analysis, the difference between groups at 18 months post-baseline in mean body weight was -0.92 kg (p=0.328; intervention=0.00, control=+0.92). Moderation analyses revealed a significant between-group intervention effect on body weight at 18 months for drivers with supervisors who engaged in higher levels of family supportive supervisor behaviours (p=0.033; group difference=-2.74 kg). Intervention effects on several diet and exercise outcomes at 18 months were also significantly moderated by social support and stress factors. Within the intervention group, high initial programme participation was associated with significantly greater 18-month weight loss than lower participation (p<0.001; -3.43 kg vs +2.17 kg).
conclusionsThe intervention produced significant long-term weight loss for truck drivers with a supportive supervisor, providing further evidence for the broad health benefits of this workplace relationship. Additional findings highlight the value of initial programme participation and may inform future replications and extensions of similar health programmes for truck drivers.
