1 · What the graph read from it

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.

2 · The registry

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

purposeLutetium-177(177Lu)-PSMA-617 improves survival for patients with metastatic castration-resistant prostate cancer, but outcomes are heterogeneous and standardized risk stratification tools are lacking. We developed a novel risk stratification tool for patients treated with 177Lu-PSMA-617.

methodsWe conducted a retrospective analysis of 163 patients at Emory Winship Cancer Institute. Four prognostic models using Cox proportional hazards models were constructed using best-subset variable selection and integrated into a composite model.

resultsAmong the 163 patients (52% White, 44% Black; 80% previous taxane use) body mass index decline during treatment was associated with shorter progression-free survival (PFS) and overall survival (OS) (HR = 1.75, P = .03; HR = 2.35, P = .031). Higher subcutaneous adipose tissue index (SATI)/skeletal muscle index (SMI) was independently associated with improved OS (HR = 0.5, P = .019), whereas higher visceral adipose tissue index (VATI)/SATI was independently associated with worse OS (HR = 2.62, P = .005). A body composition-based prognostic score identified VATI/SATI, SMI, and total adiposity as the strongest OS predictors (C = 0.629). The composite score incorporating inflammatory biomarkers and body composition demonstrated good discrimination (C-index = 0.732) and effectively stratified patients by PFS and OS. For PFS, relative risks across increasing risk quartiles were 0.34, 0.40, and 0.62 in compared with the highest risk quartile (P = .034). For OS, corresponding hazard ratios were 0.15, 0.19, and 0.54 (P = .003).

conclusionsA risk score incorporating body composition and inflammatory biomarkers demonstrates prognostic value for patients treated with 177Lu-PSMA-617.
