The National Clinical Database Risk Calculator and the 5-Item Modified Frailty Index Predict the Development of Postoperative Delirium After Surgery for 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
Aim: Postoperative delirium in elderly patients is a critical clinical issue because of its adverse effect on recovery and prognosis. The National Clinical Database (NCD) Risk Calculator, a clinical tool developed in Japan, is widely used to predict various postoperative complications, including delirium. In this study, we aimed to develop a more accurate delirium prediction model by integrating the NCD Risk Calculator with additional clinical indicators. Methods: This study included 106 patients who underwent segmentectomy or more extensive procedures for hepatocellular carcinoma between 2013 and 2023. The training cohort comprised patients treated between 2013 and 2017, and those treated afterward formed the validation cohort. In the training cohort, we assessed the NCD Risk Calculator and additional indices for the favorable-risk group, and validated the best-performing index in combination with the NCD Risk Calculator. Results: Using the median predicted risk (6.4%) as a threshold, the adverse-risk group had a significantly higher incidence of delirium than the favorable-risk group ( Conclusion: The combination of the NCD Risk Calculator and mFI-5 enhances predictive accuracy and serves as a reliable tool for assessing delirium risk in older patients.
