Risk factors for surgical site infection after general surgery in HIV-infected patients: a retrospective study.
Article in BMC infectious diseases, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundAs the number of HIV-infected patients increased, the number of patients requiring general surgery has subsequently increased. However, impairment of immune function due to HIV infection increases the risk of postoperative surgical-site infection and significant harm to patient health. This study aimed to examine the risk factors for surgical-site infection after general surgery.
methodsThe patients' data were from Zunyi fourth hospital medical information system. Machine learning based Boruta algorithm were used for variable screening. Univariable and multivariable logistic regression and restricted cubic spline analysis were performed to examine the relationship between significant variables and surgical-site infection.
resultsA total of 125 general surgery postoperative HIV-infected patients participated in the study. Surgical-site pathogen culture identified Escherichia coli, Klebsiella pneumoniae, and mixed bacteria as the three most common pathogens causing Surgical-site infection. Univariable and multivariable logistic regression analysis to adjust for risk factors identified type III surgical incision (OR = 9.92, 95% CI = 1.28-76.75) and elevated preoperative white blood cell (WBC) count (OR = 1.30, 95% CI = 1.12-1.51) as independent risk factors for postoperative surgical-site infection, whereas CD4 + T lymphocyte count greater than 400 cells/µL was identified as a protective factor (OR = 0.23, 95% CI = 0.09-0.60) while. The restricted cubic spline analysis results directly reflected the dose-response relationship between continuous variables and postoperative surgical-site infection.
conclusionsType III incision and an elevated WBC count pose a higher risk of postoperative surgical-site infection. A CD4 + T lymphocyte counts greater than 400 cells/µL provided a protective effect of lower risk of surgical site infection. Preoperative serum neutrophil percentage, albumin level, red blood cell count, and serum urea level within a specific range were beneficial in reducing the risk of incisional infections. Our research provides a theoretical basis for clinical practice.
