Survival descriptive statistics for the hierarchical DMARD groups^*

Hierarchical DMARD drug class	Time at risk (days)	Probability of change	No subjects	Survival time		Probability of no change
				25%	50%	60 days	90 days
No DMARDs	3,635	0.38	55	61	–	0.76	0.59
csDMARDs	11,983	0.23	171	–	–	0.80	0.76
TNFi†	16,124	0.25	233	80	–	0.82	0.72
NTNFi	11,855	0.25	171	76	–	0.84	0.72
JAK inhibitors	43,80	0.34	66	61	–	0.76	0.63

^*csDMARDs = conventional synthetic biologic disease‐modifying antirheumatic drugs; NTNFi = non–tumor necrosis factor inhibitors.

^† P = 0.11 by log rank test.
