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
objectivesTo evaluate lifestyle and weight changes in new male employees of Japanese companies and clarify the effects of environmental and lifestyle changes on weight changes in early years after joining the company.
methodsWe analyzed health checkup results and lifestyle questionnaires of 160 male graduates hired by a particular company between fiscal years 2009 and 2012. The data obtained included health examinations from the time of the job offer to the fourth year at the company. Weight changes were analyzed using a Friedman test. Lifestyle questionnaires were analyzed using a McNemar test. Twelve male employees who had been with the company for 5-10 years were interviewed about their lives before and after joining. The results were transcribed and analyzed using the Steps for Coding and Theorization method.
resultsCompared with employees' weight at the time of the job offer, their weight at the time of joining the company and in the second and third years increased significantly. (P <.001). An increasing number of participants ate dinner late, missed opportunities for exercise, and did not get sufficient sleep. Interview results indicated that overtime, commuting, and work-related drinking parties among new employees led to late dinners and difficulty in maintaining exercise habits, and that stress at work led to overeating.
conclusionsNew employees gained weight during their first 3 years at the company, and lifestyle changes such as overtime work, late dinners due to drinking parties, and loss of opportunities for exercise during the same period had an impact.
