Comparison of safety outcomes of anticancer drugs in Japanese and non-Japanese patients in multi-regional clinical trials: meta-analysis of safety profiles.

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
No report has assessed the differences in adverse event (AE) profiles of anticancer drugs for all types of cancers in clinical trials involving Japanese patients. This study aimed to compare the safety outcomes of anticancer drugs in Japanese and non-Japanese patients in multi-regional clinical trials (MRCTs), regardless of the type of cancer or drug. All new approvals of oncology drugs in Japan from January 2009 to December 2018 were searched through the Pharmaceuticals and Medical Devices Agency website. The odds ratio (OR) for comparing the incidence of AEs between Japanese and non-Japanese patients was estimated using the Mantel-Haenszel method with a random effect model. Sixty-six multi-regional phase 3 trials were identified involving 43,712 patients. Severe AE, AE leading to dose reduction, and AE leading to dose interruption were significantly more frequent in Japanese patients than in non-Japanese (odds ratios [ORs] were 1.32 (95% confidence interval (CI): 1.13-1.53), 1.97 (95% CI: 1.66-2.31), and 1.63 (95% CI: 1.43-1.86), respectively). Serious AEs (SAEs) and AEs leading to death were significantly less frequent in Japanese patients (OR: 0.70 (95% CI: 0.62-0.77) vs. 0.56 (95% CI: 0.44-0.67), respectively). There were no differences in AEs leading to study withdrawal. The incidence of most AEs was significantly higher in Japanese patients. In Japanese patients, the incidence of SAEs and AEs leading to death was low, but severe AEs, AEs leading to dose reductions, AEs leading to dose interruption, and individual adverse events were high.
