Trial Sequential Analysis of mortality at maximal follow‐up: azathioprine versus no intervention and colchicine versus no intervention.Based on an alpha error of 2.5%, power of 90% (beta error of 10%), a relative risk reduction (RRR) of 20%, a control group proportion observed in the trials (Pc = 20%), and diversity observed in the analyses (0%), the accrued sample size (224 for azathioprine versus intervention and 122 for colchicine versus no intervention) was only a small fraction of the diversity adjusted required information size (DARIS) (4580 for both comparisons); therefore, the trial sequential monitoring boundaries were not drawn. The Z‐curve (blue line) crossed the conventional boundaries (dotted green line) favouring azathioprine for azathioprine versus no intervention, but did not cross the conventional boundaries for colchicine versus no intervention. This indicates that there is a high risk of random errors in both these comparisons.

This indicates that there is a high risk of random errors in both these comparisons.

Trial Sequential Analysis of mortality at maximal follow‐up: ciclosporin versus no intervention and D‐penicillamine versus no intervention.Based on an alpha error of 2.5%, power of 90% (beta error of 10%), a relative risk reduction (RRR) of 20%, a control group proportion observed in the trials (Pc = 20%), and diversity observed in the analyses (82% for ciclosporin versus no intervention and 61% for D‐penicillamine versus no intervention), the accrued sample size (394 for ciclosporin versus no intervention and 423 for D‐penicillamine versus no intervention) was only a small fraction of the diversity adjusted required information size (DARIS) (25,098 for ciclosporin versus no intervention and 11,623 for D‐penicillamine versus no intervention); therefore, the trial sequential monitoring boundaries were not drawn. The Z‐curve (blue line) crossed the conventional boundaries (dotted green line) favouring ciclosporin for ciclosporin versus no intervention, but did not cross the conventional boundaries for D‐penicillamine versus no intervention. This indicates that there is a high risk of random errors in both these comparisons.
