Incidence and Predictors of Surgical Site Infection in Patients Undergoing Coronary Artery Bypass Grafting at a Reference Hospital in Brazil: Influence of Sex, Nutritional Risk, and Body Mass Index.
Article in Brazilian journal of cardiovascular surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 infection (SSI) following coronary artery bypass grafting (CABG) is a significant challenge that impacts quality of life and healthcare costs. Despite advances in surgical techniques and infection control measures, wound complications remain a major cause of morbidity and mortality. This study aimed to determine the incidence and factors associated with an increased risk of developing postoperative SSI in patients undergoing CABG.
methodsRetrospective cohort study with patients undergoing isolated CABG in a Brazilian hospital organization. Clinical data were collected through the hospital's information system. Univariate and multivariate analyses were used to determine risk factors associated with SSI. The analyses were performed using Jamovi® software, with a significance set at P < 0.05.
resultsA total of 412 patients were enrolled in the study, comprising 292 (70.8%) men, with a mean age of 62.7 ± 8.6 years. A total of 54 (13.1%) patients developed SSI. After multivariate regression analysis, the odds ratios (OR) (95% confidence interval [CI]) of independent predictors of SSI were female sex (OR: 2.067; 95% CI: 1.030 - 4.148), higher preoperative body mass index (OR: 1.113; 95% CI: 1.038 - 1.194), nutritional risk (Nutritional Risk Screening 2002 score ≥ 3) (OR: 2.468; 95% CI: 1.034 - 5.886), and hospitalization time (OR: 1.057; 95% CI: 1.031 - 1.082).
conclusionThere are patient-related factors that increase the likelihood of developing an SSI after CABG. These findings suggest that addressing modifiable perioperative SSI risk factors may be beneficial in reducing SSI rates and enhancing postoperative recovery.
