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

purposeWhile the detrimental effects of smoking on postoperative outcomes are recognized, the extent of its risk for inguinal hernia repair remains unclear. Our study aims to assess the influence of smoking on patients who undergo inguinal hernia repair.

methodsWe systematically reviewed PubMed, Embase, and Cochrane databases. Our goal was to identify studies that compared postoperative outcomes in smoking and non-smoking patients after inguinal hernia repair, and which employed a multivariate analysis to reduce possible confounding factors. Outcomes were recurrence, postoperative complications, and surgical site infection. Odds ratios (ORs) with 95% confidence intervals (CIs) were computed with the use of a random-effects model. Heterogeneity was examined with I

resultsOur analysis encompassed 11 studies, involving a total of 577,901 patients. Of these, 77,226 (or 13.4%) identified as smokers, with males constituting 90% of the cohort. In terms of surgical approaches, 58% underwent laparoscopic procedures were most common at 58%, followed by open surgeries at 41%, and 1% used robotic techniques. All included studies had a low risk of bias. Smoking was associated with a higher incidence of hernia recurrence (OR 2.95; 95% CI 2.08 to 4.18; p < 0.001; I2 = 0%). No differences were found in postoperative complication (OR 1.15; 95% CI 1.00 to 1.32; p = 0.05; I2 = 56%) or surgical site infection (OR 2.94; 95% CI 0.80 to 10.88; p = 0.11; I2 = 79%).

conclusionSmoking was associated with a three-fold increase in recurrence. Further studies are needed to evaluate the impact of preoperative smoking cessation on reducing recurrence.
