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

Objective: This systematic review and meta-analysis aimed to compare published outcomes of patients undergoing laparoscopic versus open emergency colorectal surgery, with mortality as primary outcome. Background: In contrast to the elective setting, the value of laparoscopic emergency colorectal surgery remains unclear. Methods: PubMed, Embase, the Cochrane Library, and CINAHL were searched until January 6, 2021. Only comparative studies were included. Meta-analyses were performed using a random-effect model. The Cochrane Risk of Bias Tool and the Newcastle-Ottawa Scale were used for quality assessment. Results: Overall, 28 observational studies and 1 randomized controlled trial were included, comprising 7865 laparoscopy patients and 55,862 open surgery patients. Quality assessment revealed 'good quality' in 16 of 28 observational studies, and low to intermediate risk of bias for the randomized trial. Laparoscopy was associated with significantly lower postoperative mortality compared to open surgery (odds ratio [OR] 0.44; 95% confidence interval [CI], 0.35-0.54). Laparoscopy resulted in significantly less postoperative overall morbidity (OR, 0.53; 95% CI, 0.43-0.65), wound infection (OR, 0.63; 95% CI, 0.45-0.88), wound dehiscence (OR, 0.37; 95% CI, 0.18-0.77), ileus (OR, 0.68; 95% CI 0.51-0.91), pulmonary (OR, 0.43; 95% CI, 0.24-0.78) and cardiac complications (OR, 0.56; 95% CI, 0.35-0.90), and shorter length of stay. No meta-analyses were performed for long-term outcomes due to scarcity of data. Conclusions: The systematic review and meta-analysis suggest a benefit of laparoscopy for emergency colorectal surgery, with a lower risk of postoperative mortality and morbidity. However, the almost exclusive use of retrospective observational study designs with inherent biases should be taken into account.
