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

backgroundThe rate of surgical site infection (SSI) differ with variable nature with appendicitis with a global incidence of up to 11%. Several randomised trials describe a significant reduction in incisional SSI using wound edge protectors (WEP), mainly in elective procedures. This study was designed to analyse WEP use in emergency open appendicectomy.

methodThis randomised controlled trial enrolled 200 patients who underwent emergency open appendicectomy. Permuted block randomisation was used to assign subjects to either mechanical retraction or double ring WEP. The primary endpoints were SSI rates and cost analysis between the methods.

resultsThe incidence of SSI was similar, n = 7 (7.4%) in the control group and n = 8 (8.4%) in the WEP group, and demonstrates no statistically significant difference (p > 0.05). Cost analysis showed a statistically significant (p < 0.001) higher total cost in the WEP group, MYR 456.00 (414.75, 520.00) as compared to the control group, MYR 296.00 (296.00, 300.00). However, the median cost of managing patients complicated with SSI was significantly lower at MYR 750.50 (558.75, 946.50) in the WEP group when compared to the control group MYR 1453.00 (1119.00, 2592.00) (p = 0.008).

conclusionThe use of WEP does not reduce the incisional SSI rate, and it is not cost-effective for application in all open appendicectomies. However, when faced with incisional SSI, the use of WEP had a significantly lower cost in incisional SSI management. Selective WEP use is economical in clinically suspected perforated appendicitis when laparoscopic appendicectomy approach is unsuitable.
