Real-World Analysis of the Efficacy and Adverse Events of T-DM1 in Chinese Patients With HER2-Positive Breast Cancer.

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
Purpose: This study efforts to explore the association of adverse events (AEs) with efficacy in HER2-positive breast cancer patients treated with TDM1. Methods and Materials: This retrospective study included women diagnosed with HER2+ BC treated with TDM1 from January 2012 to December 2023. Event-free survival (EFS) was the endpoint. Tumour response was assessed by disease control rate (DCR) and objective response rate (ORR). The chi-squared test, analysis of variance (ANOVA), Cox proportional hazards regression and Kaplan-Meier survival analysis was employed to evaluate the association of AEs with tumour efficacy. Results: A total of 48 women with a median age of 52 years (median follow-up 8.4 months) were included in the study. Among them, 33 patients (68.8%) experienced adverse events, including platelet depletion and liver function abnormalities, 3 patients (6.3%) discontinued TDM1 due to severe platelet depletion. The overall objective response rate (ORR) was 25.0% and the disease control rate (DCR) was 43.8%. Using the Chi-squared test, we found a statistically significant difference in ORR and DCR between patients who developed a platelet reduction and those who did not. DCR was significantly higher in patients with liver dysfunction than in those without. ANOVA showed that exposure to hepatic dysfunction and platelet reduction, lines of therapy, and treatment course were associated with EFS. In the Kaplan-Meier survival analysis, both liver dysfunction and platelet reduction were correlated with significantly longer EFS (p=0.033 and p=0.038, respectively). Conclusion: This retrospective study demonstrated that AEs were associated with tumour efficacy in patients with HER2+ BC treated with TDM1.
