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

backgroundSurgical site infection remains a major cause of postoperative morbidity. Intrawound vancomycin has been proposed as an adjunct to standard prophylaxis, but its effectiveness across surgical settings remains uncertain. This systematic review and meta-analysis of randomized clinical trials aimed to evaluate the association between intraoperative intrawound vancomycin and surgical site infection in adults undergoing surgery.

methodsMEDLINE, Embase, and CENTRAL were searched from database inception to March 2026 for randomized clinical trials comparing intrawound vancomycin with standard care in adults undergoing operative procedures. Two reviewers independently performed screening, data extraction, and risk-of-bias assessment using the Cochrane Risk of Bias 2 tool. Random-effects meta-analyses were undertaken, with certainty of evidence rated using the Grading of Recommendations Assessment, Development and Evaluation framework. Primary outcomes were overall surgical site infection, deep surgical site infection, superficial surgical site infection, and Gram-positive surgical site infection.

resultsTwenty-two trials enrolling 8424 patients (vancomycin 4228, control 4196) were included. Intrawound vancomycin was associated with a lower risk of overall surgical site infection (risk ratio 0.79, 95% confidence interval 0.64 to 0.99) and Gram-positive surgical site infection (risk ratio 0.53, 0.35 to 0.79), corresponding to numbers needed to treat of 82 and 78, respectively. No significant differences were observed for deep or superficial surgical site infection, Gram-negative infection, reoperation, wound complications, mortality, or length of hospital stay. The certainty of evidence was moderate.

conclusionIntrawound vancomycin was associated with a modest reduction in surgical site infection, driven by reductions in Gram-positive infections. These findings support a selective, context-specific use rather than routine application across all procedures.
