The impact of immune-related adverse events on survival outcomes in a racially diverse population, with a focus on non-Hispanic Black patients.

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
introductionThe development of immune-related adverse events (irAEs) has been associated with improved survival outcomes in non-small cell lung cancer (NSCLC). However, this association's extent across race and ethnicity remains uncertain. We evaluated the association between the development of irAEs and treatment outcomes across racially diverse groups treated at a safety net hospital.
methodsA retrospective chart review was performed to identify patients with advanced NSCLC treated between 2015 and 2020. The incidence of irAEs across racial subgroups was compared using logistic regression analysis. Cox regression analysis was performed to evaluate the association between the development of irAEs and treatment outcomes.
resultsWe identified 138 NSCLC patients treated with immune checkpoint inhibitors (ICIs), of whom 50% identified as non-Hispanic Black (NHB). Incidence of irAEs was 28%, with no significant difference between NHB and other racial groups. However, females [OR 2.3, 95% CI, (1.1-4.8)] and patients with Medicaid or MassHealth insurance had a higher incidence of irAEs [OR 2.7 (1.2-5.7)]. Additionally, patients with irAEs had a lower risk of disease progression (multivariable HR 0.46, 95% CI, 0.23-0.92) compared to those without irAEs. The association between irAEs and improved progression free survival (PFS) in NHB patients was similar to the other racial group [median PFS 246 vs 181 days; HR 0.87 (0.58-1.29)].
conclusionWe demonstrated a similar incidence of irAEs in NHB patients with NSCLC as compared to other racial groups. Patients who developed irAEs experienced significantly improved survival outcomes. This association remained independent of race and ethnicity, underscoring the importance of providing unbiased treatment recommendations.
