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

Immunotherapy has revolutionized cancer treatment, offering new hope for many patients. However, while some individuals show remarkable responses, the overall success rate remains limited. This has spurred interest in combination therapies, particularly with established treatments like radiation therapy (RT), to improve outcomes. RT is a cornerstone of cancer therapy and known to influence the immune landscape, yet a systematic characterization of its effects on tumor-infiltrating leukocytes (TILs) and a rationale-based therapy is still lacking. In this study, we employed a diverse set of pre-clinical syngeneic murine tumor models with varying immune profiles to investigate the immunological impact of tumor targeted RT. We observed that immunologically 'hot' tumors showed stronger tumor growth inhibition (TGI) after RT compared to 'cold' tumors. Additionally, RT induced both pro- and anti-inflammatory shifts within the tumor immune microenvironment. Importantly, RT led to an intra-tumoral increase in proliferating CD8
