They only come out at night: Impact of time of day on outcomes after penetrating abdominal trauma.
Article in Surgery open science, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPatients who present at night following penetrating abdominal trauma are thought to have more severe injuries and increased risk for morbidity and mortality. The current literature is at odds regarding this belief. The purpose of this study was to evaluate time of day on outcomes following laparotomy for penetrating abdominal trauma.
methodsPatients undergoing laparotomy following penetrating abdominal trauma over a 12-month period at a level I trauma center were stratified by age, sex, severity of shock, injury, operative complexity, and time of day (DAY = 0700-1900, NIGHT = 1901-0659). Outcomes of damage control laparotomy, ventilator days, intensive care unit length of stay, hospital length of stay, morbidity, and mortality were compared between DAY and NIGHT.
resultsA total of 210 patients were identified: 145 (69%) comprised NIGHT, and 65 (31%) comprised DAY. Overall mortality was 2.9%. Both injury severity and intraoperative transfusions were increased with NIGHT with no difference in morbidity (37% vs 40%, P = 0.63) or mortality (2.1% vs 4.6%, P = 0.31). Adjusting for sex, time of day, injury severity, and operative complexity, only abdominal abbreviated injury severity (odds ratio 1.46; 95% confidence interval 1.07-1.99, P = .019) and operative transfusions (odds ratio 1.18; 95% confidence interval 1.09-1.28, P < .0001) were identified as independent predictors of damage control laparotomy using multivariable logistic regression (area under the curve 0.96).
conclusionThe majority of operative penetrating abdominal trauma occurs at night with increased injury burden, more operative transfusions, and increased use of damage control laparotomy with no difference in morbidity and mortality. Outcomes at a fully staffed and operational trauma center should not be impacted by time of day.
