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

Aim: Acute appendicitis in pregnant women requires accurate diagnosis and treatment because of potential pregnancy complications. Laparoscopic appendectomy (LA) has been associated with higher rates of fetal loss than open appendectomy (OA). Therefore, we conducted the first multicenter collaborative analysis in Japan to evaluate the safety and efficacy of LA during pregnancy. Methods: We retrospectively reviewed 152 pregnant women who underwent appendectomy for acute appendicitis between 2012 and 2021 using data from the Japan Society of Laparoscopic Colorectal Surgery. The patients were divided into the OA ( Results: No fetal loss occurred in either group. The operative time ( Conclusions: LA is a safe alternative to OA in pregnant women, with no additional maternal complications and comparable fetal outcomes. LA does not negatively affect fetal health.
