Are all programmed cell death protein 1 inhibitors the same?
Review in Frontiers in oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Programmed cell death protein 1 (PD-1) inhibitors have revolutionized the treatment of many cancers, seven of which are approved by the US Food and Drug Administration (FDA). No head-to-head phase 3 randomized controlled trials (RCTs) comparing PD-1 inhibitors have been conducted so it remains unknown whether clinically meaningful differences exist between them. Preclinical studies that have directly compared PD-1 inhibitors support a differentiating profile associated with toripalimab compared to pembrolizumab and nivolumab with regard to their PD-1 binding sites, binding orientations, and impact on T cell function. Findings of similar or greater benefit among patients with low/no PD-L1 expression versus high/intermediate PD-L1 expression with toripalimab plus chemotherapy were also observed in advanced nasopharyngeal carcinoma and non-small cell lung cancer for both overall survival and progression-free survival. However, determination of clinically-meaningful differences between PD-1 inhibitors requires sufficiently powered head-to-head RCTs.
