An integrated host vulnerability score is associated with survival in advanced NSCLC treated with nivolumab: a PET/CT-based real-world study.

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
backgroundClinical outcomes in advanced non-small cell lung cancer (NSCLC) treated with immune checkpoint inhibitors remain heterogeneous, and simple prognostic tools for patient stratification are limited. We aimed to evaluate a multidimensional host vulnerability score integrating systemic inflammation, nutritional status, and skeletal muscle depletion in patients receiving second-line nivolumab in a real-world setting.
methodsIn this retrospective study, 110 patients with advanced NSCLC treated with second-line nivolumab were included. A composite score was constructed using neutrophil-to-lymphocyte ratio (NLR), serum albumin, and skeletal muscle index (SMI) derived from pretreatment PET/CT. Patients were stratified into lower-risk (score 0-1) and higher-risk (score 2-3) groups. Survival outcomes were assessed using Kaplan-Meier analysis, Cox proportional hazards models, and model discrimination analyses.
resultsHigh-risk patients had significantly shorter progression-free survival (median 3.4 vs. 5.9 months; HR 1.68, 95% CI 1.10-2.59; p = 0.017) and overall survival (median 7.2 vs. 14.5 months; HR 2.08, 95% CI 1.30-3.31; p = 0.002) compared with the low-risk group. In model comparison analyses, the ordinal composite score showed the clearest improvement in prognostic discrimination for overall survival, whereas its incremental value for progression-free survival was more modest.
conclusionA multidimensional host vulnerability score integrating inflammatory, nutritional, and body composition domains was associated with survival outcomes in advanced NSCLC treated with nivolumab. This score may support real-world prognostic risk stratification, particularly for overall survival, but requires prospective and external validation before clinical implementation.
