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

This meta-analysis of randomized clinical trials (RCT) aimed to compare peritoneal irrigation followed by suction with aspiration only during laparoscopic surgery for complicated appendicitis (LA). PRISMA guidelines with the random-effects model were adopted using Review Manager Version 5.3 for pooled estimates. We retained six eligible RCT published between 2012 and 2019. They involved a total of 1019 patients (541 patients in the aspiration group and 478 patients in the irrigation group). Aspiration only during LA is associated with shorter operative time (MD = 8.50 min, 95% CI [- 12.97 to - 4.02], p = 0.0002) and lower reoperation rate (OR = 0.37 95% CI [0.14-0.96], p = 0.04). There was no difference between aspiration group and irrigation group in terms of Intraperitoneal abscess (IPA) (OR = 0.99 95% CI [0.54-1.81], p = 0.95), morbidity rate (OR = 1.14 95% CI [0.44-2.98], p = 0.79), wound infection (OR = 0.94 95% CI [0.20-4.40], p = 0.94), and hospital stay (MD = 0.65 day, 95% CI [- 0.52 to 1.82], p = 0.27). Irrigation during LA prevents post-appendectomy IPA in neither adults nor pediatric patients. However, it lengthens the operative time and involves a higher reoperation rate.
