Analysis of Influencing Factors and Establishment of Nomogram Model for Textbook Outcome Achievement in Laparoscopic Resection of Hepatocellular Carcinoma.

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
Objective: To analyse the influencing factors for textbook outcome (TO) achievement in laparoscopic hepatectomy for hepatocellular carcinoma (HCC) and to construct and validate a nomogram model. Methods: A total of 200 patients with HCC who underwent laparoscopic hepatectomy in our hospital between January 2022 and December 2024 were retrospectively analysed and divided into a TO group (n = 116) and a non-TO group (n = 84) according to the TO in liver surgery criteria. Twenty clinical parameters were collected, and after univariate analysis to screen variables, multivariate logistic regression was performed to determine independent influencing factors and establish nomograms. Model discrimination, calibration and clinical benefit were assessed using receiver operating characteristic (ROC) curves, calibration curves and decision curves. Results: Multivariate logistic analysis showed that no malnutrition before operation (odds ratio [OR] = 0.051; 95% confidence interval [CI]: 0.014-0.179), intraoperative blood loss <225 mL (OR = 0.096; 95% CI: 0.030-0.310) and postoperative hospital stay <12.5 days (OR = 0.061; 95% CI: 0.021-0.182) were independent protective factors for TO (all P < 0.05). The nomogram C-index was 0.931; the area under the ROC curve was 0.983 (95% CI: 0.971-0.995), sensitivity was 0.948 and specificity was 0.929; the calibration curve fitted well with the ideal curve; and the decision curve showed that the model had a significant positive net benefit. Subgroup analysis based on resection extent (minor vs major hepatectomy) confirmed the model's robust performance, with AUCs of 0.984 and 0.976 respectively, demonstrating consistent predictive accuracy across different surgical complexities. Conclusion: Preoperative nutritional status, intraoperative blood loss and postoperative hospital stay are independent factors for achieving TO in laparoscopic resection of HCC. The constructed nomogram has excellent predictive performance and can be used to identify high-risk patients in the early clinical stage and guide individualised intervention.
