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

Background: Programmed death-1 (PD-1) inhibitors are increasingly used in neoadjuvant therapy for low rectal cancer, but complete response and toxicity remain heterogeneous. We developed and validated an albumin-based immune-nutritional score (ABINS) to capture host factors not reflected by tumor biomarkers. Methods: This multicenter retrospective study included 480 consecutive patients with low rectal adenocarcinoma (≤5 cm from the anal verge) treated with neoadjuvant PD-1-based therapy at three tertiary centers from 2018 to 2023. Patients were assigned to a training cohort (n=276), internal validation cohort (n=87), and geographically separate external validation cohort (n=117). ABINS assigned one point each for albumin <35 g/L, lymphocyte count <1.0×10 Results: Among 480 patients, 166 (34.6%) achieved composite complete response, 280 (58.3%) achieved organ preservation, and 225 disease-free survival events occurred over a median follow-up of 32.4 months. ABINS classified 333 patients (69.4%) as favorable, 87 (18.1%) as intermediate, and 60 (12.5%) as poor. Complete response decreased stepwise across these groups (42.9%, 20.7%, and 8.3%; P<0.001), as did organ preservation (66.4%, 51.7%, and 23.3%; P<0.001), whereas grade ≥3 toxicity increased (7.5%, 19.5%, and 23.3%; P<0.001). After multivariable adjustment, each one-point ABINS increase independently predicted lower complete response (OR 0.51, 95% CI 0.41-0.65), higher grade ≥3 toxicity (OR 1.75, 95% CI 1.37-2.23), and worse disease-free survival (HR 1.42, 95% CI 1.27-1.60; all P<0.001). Adding ABINS improved external-cohort AUC from 0.703 to 0.772 and reduced Brier score from 0.190 to 0.161. Conclusions: ABINS is a simple, inexpensive host immune-nutritional score that improves risk stratification for complete response, organ preservation, toxicity, and survival after neoadjuvant PD-1-based therapy in low rectal cancer. Prospective validation is warranted.
