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

backgroundPD-1 inhibitors have revolutionized cancer immunotherapy but present significant neurological safety concerns. While clinical trials have documented neurological adverse events (nAEs), a comprehensive understanding of their patterns and risk factors remains limited. This study systematically analyzed a decade of FAERS data to investigate PD-1 inhibitor-associated neurotoxicities.

methodsUsing FAERS data (2014-2024), we conducted disproportionality analyses (ROR, IC, PRR) to assess PD-1 inhibitor-nAE associations. Risk factors were evaluated using logistic regression; timing analyses used log-rank and Mann-Whitney U tests, while group comparisons used Chi-square tests.

resultsAmong 115,000 PD-1 inhibitor-associated adverse events, 7968 (6.93%) involved nAEs, showing an increasing trend from 4.96% (Q4 2014) to 7.67% (Q1-Q2 2024). PD-1 inhibitors showed significant nAE signals (ROR: 1.21, 95% CI: 1.18-1.23), with cemiplimab showing the strongest association (ROR: 1.38, 95% CI: 1.18-1.62). The most common nAEs were dizziness (N = 942, 10.3%), encephalitis (N = 435, 4.8%), and cerebrovascular accident (N = 451, 4.9%). Risk factors included age > 65 years (OR: 1.10), female sex (OR: 1.04), skin cancer (OR: 1.36), and nervous system cancers (OR: 1.44). The median onset time was 34 days (IQR: 12-104), with 63.8% occurring within 2 months and 59% resulting in severe outcomes.

conclusionThis study reveals a spectrum of PD-1 inhibitor-related neurological toxicities, mainly involving central nervous system dysfunction, providing important insights into risk patterns and timing characteristics. These findings support improved clinical monitoring practices and inform the development of personalized patient care strategies.
