Clinically interpretable nomogram combining body composition and clinicopathological features for one year survival prediction in advanced solid tumors.
Article in Scientific reports, 2026. 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
Immune checkpoint inhibitors (ICIs) have improved outcomes for patients with solid tumors, but reliable predictors of overall survival (OS) are limited. This retrospective study of 146 advanced solid tumor patients treated with ICIs aims to provide a nomogram to predict 1-year (1y) OS integrating body composition (BC) parameters with standard clinicopathological (CP) features. A two-stage approach was implemented: first random survival forest models were trained and tested to evaluate the prognostic value of (a) CP features alone, (b) BC metrics alone or as newly introduced BC scores, and (c) their combination. The best predictive performance (average cumulative AUC of 0.73 in test set) was achieved by combining 12 CP features with the BC score comprising intramuscolar adipose tissue content, visceral fat area index, and the visceral-to-subcutaneous fat area index ratio. Finally, a nomogram was developed with this feature set, offering a tool for personalized risk stratification and treatment planning (mean absolute error in calibration curve of 0.03 and overall AUC of 0.76). Integrating BC parameters with CP features substantially enhances 1y OS prediction in patients receiving ICIs.
