Incidence of severe adverse events in cancer patients after treatment with immune-checkpoint inhibitors during the COVID- 19 pandemic.

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
Immune-checkpoint inhibitors (ICIs) can cause inflammation and immune-related adverse events (irAEs). Although irAEs may be caused by dysregulation of cytokines, the impact of various COVID- 19-related factors on expression of ICI-related AEs remains unclear. Assessment of AEs following ICI administration during the COVID- 19 pandemic may provide valuable insights that enable optimization of patient selection, thereby maximizing the benefits of ICI therapy. The aim of this study was to investigate the actual occurrence of severe AEs after ICI administration during the COVID- 19 pandemic. The medical records of patients who received ICI at Saga University Hospital were examined retrospectively. The primary endpoint was the incidence of all AEs ≥ Grade 3 that occurred after ICI administration. The survey period, from Jan 2020 to Dec 2022, was divided into an earlier (Jan 2020-March 2021) and a later (April 2021-Dec 2022) period. AEs with a clear cause other than ICI were excluded from the analysis. A total of 527 patients were included in the analysis, with a median follow-up of 422 days. During the COVID- 19 pandemic, the incidence of AEs ≥ Grade 3 after ICI administration was 52.8%. The incidence of AEs ≥ Grade 3 AEs after ICI administration was significantly higher during the later period [23.4% (57/244) in the earlier period and 49.8% (236/474) in the later period; mixed effect model p < 0.0001, odds ratio, 3.37 (95% CI: 2.32-4.89)]. Overall survival was significantly worse in the group with AEs ≥ Grade 3 than in the group without AEs ≥ Grade 3 [HR (95% CI) = 0.48 (0.36-0.65), p = 0.0001]. During the COVID- 19 pandemic, it became clear that the incidence of severe AEs (including irAEs) increased after ICI administration, particularly during the later period of the disease. Various factors may be associated with occurrence of severe AEs after ICI administration, and long-term careful observation and prospective multicenter clinical studies are required.
