Effect of age (per year) on the probability of remission for 6 and 12 months

	6 months		12 months
	OR	95% CI	OR	95% CI
Both P and C	1.71	1.11 to 2.62	1.31	1.04 to 1.65
Prednisone	1.23	1.05 to 1.45	1.19	1.06 to 1.32
CyA/FK506	1.45	1.07 to 1.96	1.39	1.09 to 1.79

Results of primary analysis are in bold (6-month remission free from both oral agents). For each of the 6 models the outcome is defined based on the duration of the remission (6 and 12 months) and the drug that was withdrawn. OR indicates odds ratio; 95% CI indicate 95% confidence intervals. All models take into account the correlation in the data due to repeated observations in the same subject (mixed models) and are adjusted for number of rituximab cycles (see methods). Disease duration, toxicity, sex and baseline body weight did not have any effect. ‘Both P and C’ indicates remission free from both prednisone and calcineurin-inhibitors; ‘Prednisone’ indicates remission free from prednisone, but not from calcineurin-inhibitors; ‘CyA/FK506’ indicates remission free from calcineurin-inhibitors but not from prednisone.
