Factors associated with skin exposure of central venous ports in patients undergoing chemotherapy: a retrospective study.
Observational study in BMC cancer, 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
backgroundSkin exposure of central venous (CV) ports is a rare but serious complication in patients undergoing outpatient chemotherapy. While nutritional and procedural factors have been implicated in wound complications, little is known about the specific risk factors for CV port skin exposure.
methodsThis retrospective observational study included 190 patients who underwent CV port implantation for outpatient chemotherapy between January 2020 and December 2023. After excluding 32 patients with missing data, 158 patients were analyzed and divided into two groups based on the presence or absence of skin exposure of the port. Clinical and procedural characteristics were compared, and multivariate logistic regression analysis was performed to identify independent risk factors.
resultsAmong the 158 patients, 10 (6.3%) experienced skin exposure of the CV port. Compared with patients without exposure, those in the exposure group had significantly lower BMI (18.3 [17.2–21.3] vs. 21.1 [20.1–24.6], p = .044) and serum albumin levels (3.4 [3.1–3.8] g/dL vs. 4.1 [3.7–4.3] g/dL, p = .003). Male sex (p = .032) and left anterior chest placement (p = .023) were also significantly associated with exposure. Multivariate analysis identified male sex, hypoalbuminemia, and left-sided port placement as independent risk factors. ROC analysis showed that serum albumin (AUC = 0.826) had better predictive performance than BMI (AUC = 0.777).
conclusionsMale sex, hypoalbuminemia, and left anterior chest placement were independently associated with CV port skin exposure in patients undergoing chemotherapy. These findings highlight the importance of pre-procedural nutritional assessment and individualized port placement strategies to reduce the risk of skin-related complications.
