Reduction of wound infections in laparoscopic-assisted colorectal resections by plastic wound ring drapes (REDWIL)?--A randomized controlled trial.

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.
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
introductionSurgical site infections (SSIs) are frequent complications in colorectal surgery and may lead to burst abdomen, incisional hernia, and increased perioperative costs. Plastic wound ring drapes (RD) were introduced some decades ago to protect the abdominal wound from bacteria and reduce SSIs. There have been no controlled trials examining the benefit of RD in laparoscopic colorectal surgery. The Reduction of wound infections in laparoscopic assisted colorectal resections by plastic wound ring drapes (REDWIL) trial was thus designed to assess their effectiveness in preventing SSIs after elective laparoscopic colorectal resections. MATERIALS/
methodsREDWIL is a randomized controlled monocenter trial with two parallel groups (experimental group with RD and control group without RD). Patients undergoing elective laparoscopic colorectal resection were included. The primary endpoint was SSIs. Secondary outcomes were colonization of the abdominal wall with bacteria, reoperations/readmissions, early/late postoperative complications, and cost of hospital stay. The duration of follow-up was 6 months.
resultsBetween January 2008 and October 2010, 109 patients were randomly assigned to the experimental or control group (with or without RD). Forty-six patients in the RD group and 47 patients in the control group completed follow-up. SSIs developed in ten patients with RD (21.7 %) and six patients without RD (12.8 %) (p = 0.28). An intraoperative swab taken from the abdominal wall was positive in 66.7 % of patients with RD and 57.5 % without RD (p = 0.46). The number of species cultured within one swab was significantly higher in those without RD (p = 0.03). The median total inpatient costs including emergency readmissions were 3,402 ± 4,038 <euro> in the RD group and 3,563 ± 1,735 <euro> in the control group (p = 0.869).
conclusionsRD do not reduce the rate of SSIs in laparoscopic colorectal surgery. The inpatient costs are similar with and without RD.
