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

aimSurgical site infection (SSI) and incisional hernia (IH) are common complications following midline laparotomy. The small-bites technique for closing a midline laparotomy has been suggested to improve SSI and IH rates compared with the classic mass closure. The aim of this work was to perform a systematic review, meta-analysis and fragility assessment of existing evidence comparing small-bites and conventional closure.

methodThe study was registered with PROSPERO. A systematic search of PubMed and EMBASE databases was performed for all comparative studies examining small-bites versus conventional closure for midline laparotomy. The fragility index for randomized controlled trials (RCTs) was assessed and the number of outcomes required to render results insignificant using the Fisher exact test was calculated.

resultsSeven studies were included, with a total of 3807 patients. Small bites was performed in 1768 and large bites in 2039. Follow-up ranged from 12 to 52 months. On meta-analysis of all studies, small bites is associated with a lower risk of IH (p < 0.00001), SSI (p = 0.0002) and wound dehiscence (p = 0.02). On meta-analysis of RCTs there is a lower risk of IH (p = 0.01) but no difference in SSI (p = 0.06) or wound dehiscence (p = 0.73). Fragility is evident among RCTs reporting differences in IH rates.

conclusionThere is evidence to suggest that small-bites closure provides a decreased likelihood of IH over varying follow-up in RCTs but significant fragility exists among studies.
