Prognostic predictive value of sarcopenia and systemic immune-inflammatory index in patients after radical surgery for distal cholangiocarcinoma.
Article in Scientific reports, 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
To investigate the predictive value of sarcopenia and systemic immune-inflammatory index (SII) for short-term complications and long-term outcome after radical surgery in patients with distal cholangiocarcinoma. Retrospective collection of clinical data from patients who underwent radical surgery for distal cholangiocarcinoma was conducted. The patients were then divided into two groups: sarcopenia group and normal group, based on their skeletal muscle index (SMI). Logistic regression was employed to analyze the risk factors for major postoperative complications (Clavien-Dindo ≥ grade III). Additionally, Cox proportional hazards model was used to identify independent risk factors for overall survival (OS) and disease-free survival (DFS). Also, a nomogram model was developed for predicting OS and DFS at 1 and 3 years after surgery. A total of 111 patients were finally included in the study based on the inclusion-exclusion criteria. Multifactorial logistic regression analysis revealed that sarcopenia was an independent risk factor for major postoperative complications in distal cholangiocarcinoma patients (P < 0.001). Furthermore, multifactorial Cox regression analysis indicated that sarcopenia and high SII levels were independent risk factors affecting OS and DFS (P < 0.05). A nomogram model, incorporating preoperative sarcopenia, SII, and other factors, exhibited strong predictive efficacy, calibration, and clinical utility for OS and DFS after radical surgery. Sarcopenia and high SII levels are associated with poor prognosis and are independent risk factors for OS and DFS in patients undergoing radical surgery for distal cholangiocarcinoma. Sarcopenia and SII are convenient, inexpensive, and reliable markers for improving postoperative prognosis and new therapeutic strategies for patients with distal cholangiocarcinoma.
