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

Objectives: Since 2011, immune checkpoint inhibitors (ICI) have transformed the treatment of various cancers. However, our understanding of the autoimmune adverse events, particularly those affecting the nervous system, remains limited. These adverse events can cause significant disability or even death, yet there are currently no established guidelines or biomarkers to aid diagnosis and treatment. With this study, we aim to gain a deeper understanding of neurological adverse events and investigate potential predictive biomarkers. Methods: Between 19 December 2019 and 21 August 2021, 150 out of 543 ICI-treated cancer patients were eligible for our prospective monocentric cohort study. Neurological assessments, clinical scores and the severity of side effects were analysed. Blood samples were taken before, during and after therapy. Patients with neurological AEs (the nAE group) and those without (the non-nAE group) were compared to identify potential predictive markers. Results: Of the 150 patients, 55 (36.7%) experienced nAE of any kind or severity, ranging from non-specific neurological symptoms to severe events. Severe nAE (Grade ≥ 3) was observed in 3.3% of patients and included cases of encephalitis and cerebral vasculitis. Regarding potential biomarkers, an increase in C-reactive protein (CRP) within the first 3-4 weeks was statistically associated with an increased likelihood of nAE in this study. As for patient- and treatment-related parameters, concurrent chemotherapy was found to be significantly associated with the occurrence of nAE. Conclusions: This study observed a relatively high rate of nAE under ICI therapy, partly due to the intentionally broad case definition. CRP elevation emerged as a potential predictive biomarker, warranting further investigation. However, other statistically significant markers did not consistently demonstrate clinical relevance.
