Association between immune checkpoint inhibitors and cardiovascular risks: a nationwide self-controlled case series study.
Article in American journal of cancer research, 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
Immune checkpoint inhibitors (ICIs) are widely used for cancer treatment but are linked to potential cardiotoxicity. The time-dependent effects of ICIs on cardiovascular outcomes remain unclear. This study explores associations between ICI use and cardiovascular events. This self-controlled case series (SCCS) analyzed cancer patients who received ICIs from January 2019 to December 2020 using the National Health Insurance Research Database (NHIRD). Exposure periods were defined as the duration of ICI prescriptions plus 90 days. Poisson regression estimated incidence rate ratios (IRRs) for heart failure (primary outcome) and arterial events or perimyocarditis (secondary outcomes) during and after ICI exposure compared to baseline. Among 1,146 ICI users, 15 developed heart failure, 33 experienced arterial events, and 11 had perimyocarditis. Cardiovascular events were uncommon but showed elevated risks for heart failure (IRR: 7.73; CI: 2.05-29.14, P<0.01) and perimyocarditis (IRR: 8.25; CI: 1.60-42.50, P = 0.01) within 30 days of ICI exposure. Subgroup analysis identified higher risks in patients aged ≥65, males, and those with diabetes, hypertension, or hyperlipidemia. Furthermore, when focusing on patients who received more than two doses of ICIs or exclusively anti-PD-1 inhibitors, we observed a similarly increased risk of HF within 30 days post-exposure. Collectively, ICI exposure significantly elevates the risk of heart failure and perimyocarditis within 30 days, particularly in older adults and those with preexisting cardiovascular risk factors.
