MATES in Manufacturing: A Cluster RCT Evaluation of a Workplace Suicide Prevention Program.
Trial report in American journal of industrial medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe MATES in Construction suicide prevention program was adapted to the manufacturing sector and evaluated in a pilot of the program.
methodsTen manufacturing worksites were randomly assigned to intervention (5 sites) and wait-list control (5 sites) conditions in a two-arm cluster randomized design. 1245 workers responded at baseline (87% response rate) and 648 at final (35% response rate). Literacy of Suicide Scale (LOSS) was assessed as a process outcome, and help-seeking intentions as the primary outcome (General Help-Seeking Questionnaire [GHSQ] score). Secondary outcomes included help sought, suicidal thoughts and likelihood of suicide attempt scores, and Kessler-6 scores. Linear mixed models for repeated measures were used in intention-to-treat (ITT) and completer analyses.
resultsAll sites finished the trial, with intervention periods ranging from 8 to 11 months; however, none of the five intervention sites fully implemented the intervention as planned. ITT analyses showed an improvement in LOSS scores within the intervention group (0.49, 95% CI 0.13-0.49), but the mean difference in change between intervention and control included the null (0.34, 95% CI -0.10 to 0.80). The primary outcome of GHSQ scores also improved within the intervention group, but the difference in change included the null (mean difference 1.52, 95% CI -0.69 to 3.74). No secondary outcomes improved relative to control in ITT or completers analyses. Exploratory analysis of disaggregated GHSQ help sources showed greater improvement in mean difference in change for the main MATES message of seeking help from MATES Connectors.
conclusionThe intervention, as implemented, was not effective at achieving the primary or secondary outcomes.
