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
Background: Chimeric antigen receptor T-cell (CAR-T) cell therapy represents a significant advancement in cancer treatment, offering remarkable responses in certain hematologic malignancies. However, the risk of secondary primary malignancies (SPMs) associated with CAR-T therapy is a growing concern. Recent studies suggest that antibiotics, which are frequently used in CAR-T patients, may influence this risk, yet their effects remain poorly understood. Objective: This study aims to systematically evaluate the association between antibiotics and the incidence and timing of SPMs in patients receiving CAR-T cell therapy, using data from the FDA's Adverse Event Reporting System (FAERS) database. Design: We analyzed reports from FAERS spanning from Q2 2017 to Q1 2024, focusing on SPMs associated with various CAR-T therapies. Methods: A comprehensive signal analysis was conducted to explore the associations between antibiotic usage and specific SPMs for different CAR-T products. In addition, we employed cumulative hazard curves to evaluate the time to onset of SPMs in patients receiving antibiotics versus those who did not. Results: We have provided a comprehensive summary of all signals for CAR-T-associated SPMs. In addition, our analysis identified significant variations in the association between antibiotics and SPM incidence depending on the CAR-T therapy administered. Antibiotics were associated with a decreased risk of SPMs in patients treated with anti-CD19 CAR-T therapies, particularly brexucabtagene autoleucel. Conversely, a higher risk of SPMs was observed in association with antibiotics for anti-BCMA therapies, with idecabtagene vicleucel showing a notably elevated risk. Notably, antibiotics were associated with an earlier onset of SPMs across CAR-T therapies, suggesting a possible relationship between antibiotics and the timing of these malignancies. Finally, we explored the underlying biological pathways that may be associated with these observations. Conclusion: Antibiotics were associated with both the risk and timing of SPMs in patients undergoing CAR-T cell therapy. This study highlights the need for further research to better understand the complex interactions between antibiotics and CAR-T therapies, as well as the potential implications for clinical management and patient care.
