Evaluating a new voluntary occupational health and safety management system program in the context of a pandemic.

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
objectivesShortly before the COVID-19 pandemic, the Workplace Safety and Insurance Board of Ontario, Canada, launched the Health and Safety Excellence program (HSEp), a new voluntary occupational health and safety management system (OHSMS) program. This study conducted a prospective evaluation for the impact of HSEp participation on injury rate reduction during an ongoing pandemic.
methodsA difference-in-differences study design with a hybrid matching approach was used to evaluate HSEp's effectiveness in reducing lost-time injury rates with and without COVID-19 claims among participating firms compared with similar non-participating firms. The analysis was stratified by enrollment cohort, industry, firm size, and prior OHSMS experience.
resultsA total of 1680 matched HSEp firms were followed for 48 months. Some evidence of an effect on lost-time injury rates was observed, particularly after excluding COVID-19 claims. Non-COVID-19 lost-time rate reductions were pronounced among firms that enrolled later [incidence rate ratio (IRR) 0.89, 95% confidence interval (CI) 0.82-0.98], manufacturing firms (IRR 0.81, CI 0.68-0.96), larger firms (IRR 0.92, CI 0.85-0.99), and firms that had progressed through the program (IRR 0.91, CI 0.83-0.98). However, the reductions were not apparent among healthcare and construction companies or smaller firms.
conclusionsAlthough the evidence of overall injury rate reductions is limited, emerging evidence suggests that participating in HSEp is associated with reductions in non-COVID-19 injuries in certain contexts. These findings suggest that the OHSMS program performance was affected by the pandemic, and accounting for this was crucial in assessing an intervention effect.
