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

backgroundExtralevator abdominoperineal excision (ELAPE) of rectal cancer has been proposed to achieve better oncological outcomes. The resultant wide perineal wound, however, presents a challenge for primary closure and subsequent wound healing. This meta-analysis compared the outcomes of primary perineal closure with those of biological mesh reconstruction.

methodsThe Medline and Embase search was performed for the publications comparing primary perineal closure to biological mesh reconstruction. Early perineal wound complications (seroma, infection, dehiscence) and late perineal wound complications (perineal hernia, chronic pain, and chronic sinus) were analyzed as primary endpoints. Intraoperative blood loss, operation time, and hospital stay were compared as secondary endpoints.

resultsThere was no significant difference in the overall early wound complications after primary closure or biological mesh reconstruction (odds ratio (OR) of 0.575 with 95% confidence interval (CI) of 0.241 to 1.373 and a P value of 0.213). The incidence of perineal hernia after 1 year was significantly high after primary closure of the perineal wounds (OR of 0.400 with 95% CI of 0.240 to 0.665 and a P value of 0.001). No significant differences were observed among other early and late perineal wound complications. The operation time and hospital stay were shorter after primary perineal closure (p 0.001).

conclusionA lower incidence of perineal hernia and comparable early perineal wound complications after biological mesh reconstruction show a relative superiority over primary closure. More randomized studies are required before a routine biological mesh reconstruction can be recommended for closure of perineal wounds after ELAPE.
