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

purposePerineal wound infection (PWI) rates are high after abdominoperineal resection (APR) and total pelvic exenteration (TPE). This study identified risk factors for PWI after surgery for anorectal tumors and examined the relationship between the surgical excision volume with the PWI degree.

methodsA retrospective review involving 135 patients who underwent surgical excision of anorectal tumors was performed. Superficial PWI included cellulitis and superficial dehiscence; deep PWI included major dehiscence, perineal abscess, and presacral abscess. The adjacent organ resection type was classified according to the dead space size formed by surgical excision.

resultsOf the 135 patients, 119 underwent APR, and 16 underwent TPE. PWI occurred in 75 patients (superficial PWI, 44; deep PWI, 31). Adjacent organ resection was an independent risk factor for PWI. The cases with adjacent organ resection were classified into small-defect APR, large-defect APR, and TPE. Large-defect APR and TPE cases had significantly higher rates of deep PWI than APR cases without adjacent organ resection.

conclusionsAdjacent organ resection involving the removal of one or more organs and that involving wide-range muscle resection are strong risk factors for deep PWI.
