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

Combining radiotherapy with immune checkpoint inhibitors (RT-ICI) triggers systemic antitumor responses, such as abscopal effects (AbE). Predictors of AbE and its impact on survival in real-world settings remain poorly defined. This multicenter, retrospective cohort study assessed the prevalence of AbE in ICI-refractory progressive metastatic patients by evaluating the additive effect of RT on nonirradiated lesions (NIL). We screened 3773 cases to identify patients with stage IV tumors receiving RT during/after ICI. Abscopal benefit (AB) was defined as abscopal response (AR) or control (AC) by measuring NILs according to iRECIST. AB was observed in 61.3% of 142 included patients and associated with improved median overall survival (18 vs. 8 months,
