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

backgroundThere is a lack of evidence regarding the impact of body weight on the safety of surgical abortion. STUDY

designWe performed a systematic review and meta-analysis of observational studies reporting the effects of obesity on perioperative anaesthetic and surgical outcomes during surgical abortion. Analytical observational studies examining individuals undergoing surgical abortion up to 28 weeks gestation were eligible for inclusion if they reported perioperative anaesthetic or surgical outcomes in participants with body mass index (BMI) in two groups: BMI < 30 kg/m

resultsEight retrospective cohort studies were included, comprising 9912 obese and 31 672 non-obese participants. 1770 participants had BMI ≥ 40 kg/m

conclusionsAnaesthetic and surgical risks are not increased by BMI ≥ 30 kg/m
