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.

Abstract

purposeEmergency abdominal surgery results in a high rate of post-operative complications and death. There are limited data describing the emergency surgical population in details. We aimed to give a detailed analyses of complications and mortality in a consecutive group of patients undergoing acute abdominal surgery over a 4-year period.

methodsThis observational study was conducted between 2009 and 2013 at Copenhagen University Hospital Herlev, Denmark. All patients scheduled for emergency laparotomy or laparoscopy were included. Pre-, intra-, and post-operative data were collected from medical records. Complications were registered according to the Clavien-Dindo classification. Cox regression analysis was performed to identify risk factors for mortality.

resultsA total of 4,346 patients underwent emergency surgery, of whom 14 % had surgical complications and 23 % medical complications. The overall 30-day mortality was 8 % with 50 % of those in this group over 80 years of age. The 30-day mortality rates were 0.8 % (95 % CI 0.5-1.1) and 17 % (95 % CI 15.5-18.9), respectively, for the laparoscopy and the laparotomy groups. The overall death rate within 24 h of surgery was 21 %. Several risk factors for 30- and 90-day mortality were identified: age, ASA ≥3 (American Society of Anaesthesiologists physical status classification), performance score (Zubroed/WHOclassification), cirrhosis of the liver, chronic nephropathy, several medical conditions, and malignancy.

conclusionAlmost one in five patients died after emergency laparotomy, of whom one in five died within 24 h of surgery. Predictors for poor outcome were identified.
