Associations Between Pre-Existing Autoimmunity and Chimeric Antigen Receptor T Cell Therapy Toxicity for Cancer Treatment.
Article in ACR open rheumatology, 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
objectiveChimeric antigen receptor (CAR) T cell therapy is being investigated to treat individuals with autoimmune diseases. Data regarding the safety of CAR T cell therapy in this population are limited. We aimed to assess whether pre-existing autoimmune disease was associated with an increase in major toxicity or hospital length of stay (LOS) among patients receiving CAR T cell therapy for the treatment of hematologic cancer.
methodsThis retrospective cohort study used data from the National Inpatient Sample (2021-2022) to investigate in-hospital outcomes in adult patients receiving CAR T cell therapy. Comparisons were drawn between patients with and without pre-existing autoimmune disease. Multivariable regression models with adjustment for age, sex, race, cancer type, and comorbidities assessed associations with hospital LOS, major toxicity, and inpatient mortality.
resultsAmong 1,321 patients receiving CAR T cell therapy, 62 (4.7%) had diagnosed autoimmune disease. Patients with pre-existing autoimmunity had a significantly shorter hospital stay compared with patients without, with a mean reduction of 2.1 days (95% confidence interval [CI] 0.5-3.6). Major toxicity was less frequent in patients with pre-existing autoimmunity than patients without (67.7% vs 78.6%, respectively; adjusted odds ratio 0.55; 95% CI 0.31-0.99). Inpatient mortality did not differ significantly between groups.
conclusionPatients with pre-existing autoimmune disease had shorter hospital stays and lower risk of major toxicity following CAR T cell therapy for cancer treatment, offering reassurance as to its safety in this population while providing additional data for research studies of CAR T cell therapy to treat autoimmune diseases.
