A web-based predictive model for secondary skin infections in breast cancer patients undergoing reconstruction.
Article in Gland surgery, 2025. 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
Background: Breast cancer (BC) is one of the most common malignancies in women worldwide, with surgical interventions such as mastectomy and implant-based reconstruction playing a key role in management. While implant-based reconstruction offers immediate breast contour restoration, complications such as infection, capsular contracture, and implant failure are influenced by patient-specific factors, including age, body mass index (BMI), smoking, and adjuvant therapies like radiation. This study aimed to develop a predictive model for postoperative skin infections to enhance personalized risk assessment and optimize surgical outcomes in BC patients. Methods: This retrospective study included 166 Chinese female patients with BC who underwent unilateral mastectomy followed by implant-based reconstruction. Univariate and multivariate logistic regression analyses were conducted to identify independent risk factors for postoperative skin infections. A nomogram was constructed based on significant variables, with its accuracy assessed using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). Results: The 166 patients were divided into training and validation cohorts (6:4). Univariate analysis identified BMI, chemotherapy, radiotherapy, and prosthesis thickness as significant factors for postoperative skin infections. Multivariate analysis confirmed BMI, chemotherapy, and prosthesis thickness as independent risk factors. The predictive model demonstrated strong performance, with area under the curve (AUC) values of 0.87 and 0.812 for the training and validation cohorts, respectively. Calibration curves showed good agreement between predicted and observed outcomes, and DCA confirmed the model's clinical utility. A web-based calculator was developed to estimate infection risk (https://kevinpan.shinyapps.io/InfectionStatus/). Conclusions: BMI, prosthesis thickness, and chemotherapy are key factors influencing the risk of postoperative skin infections in BC patients undergoing implant-based reconstruction. The predictive model developed in this study provides a valuable tool for clinicians to assess risk and personalize treatment plans. Further studies with larger cohorts are needed to validate and refine the model for broader clinical use.
