The analysis of postoperative wound healing, infection risk prediction, and nursing intervention strategies for elderly patients with lung cancer.
Article in BMC geriatrics, 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
backgroundLung cancer poses a significant public health challenge, particularly among the elderly population, with implications for postoperative outcomes following surgical intervention. However, the comprehensive analysis of factors affecting postoperative wound healing and infection risk, along with the impact of targeted nursing interventions, remains understudied in this patient population.
methodsThis retrospective case-control study involved elderly patients who underwent lung cancer surgery. Data on patient demographics, disease-related features, surgical and clinical parameters, postoperative biomarkers, complications, and nursing interventions were analyzed. Statistical analyses, including t-tests, chi-square tests, correlation analysis, logistic regression, and predictive value analyses, were performed to investigate the associations and predictive values of various factors with postoperative wound healing and infection risk.
resultsIn this retrospective case-control study, we compared the demographic characteristics of 197 patients with good wound healing to a group of 106 patients with poor wound healing, then the patients were divided into 275 patients in non-infected and 28 patients in infected groups based on postoperative infection status. Age and Charlson Comorbidity Index showed significance in postoperative wound healing. Disease-related features such as lung cancer stage, histological type, and diabetes mellitus were associated with wound healing and infection risk. Surgical duration, intraoperative blood loss, postoperative complications, and specific biomarkers correlated with wound healing. Postoperative complications, specifically pneumonia, atelectasis, wound infection, and pleural effusion, were more prevalent in the group with poor wound healing. Nursing interventions including early mobilization, nutritional support, pain management, and antibiotic prophylaxis were more common in the group with good wound healing.
conclusionAge, comorbidities (particularly Charlson Comorbidity Index of 5.57 versus 4.92), and advanced cancer stage were significant predictors of poor wound healing. Early mobilization (85.28% versus 70.75%), nutritional support, pain management, and antibiotic prophylaxis demonstrated protective effects against poor wound healing and infection in elderly lung cancer patients.
