The off-hour effect among severe trauma patients: a nationwide cohort study in Japan.
Article in Surgery today, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeTo assess whether there are temporal differences altering the clinical outcomes of severe trauma patients in Japan.
methodsThis was a retrospective cohort study that used recorded data from the Japan Trauma Data Bank. Severe trauma patients who had an injury severity score of greater than 16 were included. The hospital arrival time was categorized into daytime (8 a.m.-7:59 p.m.) and nighttime (8 p.m.-7:59 a.m.). The hospital arrival day of the week was categorized into business days and non-business days. The primary outcome was in-hospital mortality.
resultsA total of 65,136 severe trauma patients were analyzed. In-hospital mortality was 15.6% in the daytime and 14.4% in the nighttime, and 15.5%, and 14.6% on business days and non-business days, respectively. Nighttime was associated with decreased in-hospital mortality compared to daytime (odds ratio = 0.817, 95% confidence interval = 0.764-0.874) and a non-business day was not associated with in-hospital mortality.
conclusionsWe did not find a negative off-hour effect on in-hospital mortality among severe trauma patients.
