1 · What the graph read from 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.

2 · The registry

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

objectivesStrengthening the research workforce is essential to safeguard public health and human lives. This study examined the associations between work hours and perceived performance appraisal, and the intention to leave the medical research workforce.

methodsThis cross-sectional study used data collected from medical researchers between December 2022 and January 2023. The questionnaire was distributed to participants via all 141 societies of the Japanese Association of Medical Sciences. Weekly work hours were self-reported using 10 response options. Perceived appraisal of research performance at work was assessed using 6 response options and dichotomized into inappropriately appraised (slightly disagree/totally disagree) and the rest. Intention to leave the research workforce was also self-reported and dichotomized. We calculated multivariable-adjusted odds ratios (aORs) for intention to leave, according to work hours and perceived appraisal.

resultsOf 3139 participants (852 women), most (n = 686) worked 60-79 hours weekly. One in four (n = 745) felt inappropriately appraised, and 11% (n = 356) intended to leave. A U-shaped association was observed between work hours and intention to leave (aOR: 2.05; 95% CI, 1.12-3.73, for weekly working 100 hours or longer), although the quadratic trend was not significant (P = .15). The inappropriately appraised group had a 3.6 times (95% CI, 2.81-4.58) higher OR of intending to leave compared with their appropriately appraised counterparts.

conclusionsThe results suggest that researchers who work long hours and feel inappropriately appraised are more likely to consider leaving the medical research workforce.
