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

Nonrestorative sleep (NRS) is clearly more associated with objective indices than primary insomnia symptoms. Stress is a comorbid factor for NRS. In 2015, the Stress Check Program was launched in Japan as a new occupational health policy. This study aimed to clarify whether the presence or absence of high job stress (HJS), as determined by Brief Job Stress Questionnaire (BJSQ), is related to the comorbidity of NRS. The subjects were 23,813 Japanese office workers who were 20 to 59 years old. The results of the BJSQ and medical examinations from a single year were examined. Presence or absence of HJS was assessed using the BJSQ and investigated in a medical interview using a personal computer. Additionally, HJS and NRS comorbidity were analyzed to determine if there were relationships between them. The subjects had a mean age of 43.2 ± 10.7 years. The proportions of subjects with NRS and HJS were 27% and 10%, respectively. HJS was associated with a risk of NRS (odds ratio, 3.68; 95% confidence interval, 3.35-4.03;
