Association between age and absolute lymphocyte count (ALC) <LLN at months 6 and 12.

	n	Category	n/N (%) <LLN	ORa	Predictor p-valueb
Month 6
Baseline ALC	137	Continuous predictor		0.51	0.0106
Age at baseline, years	137	≤50	18/72 (25)	1.24	0.7003
		>50	19/65 (29)
Month 12
Baseline ALC	117	Continuous predictor		0.78	0.2154
Age at baseline, years	117	≤50	15/51 (29)	2.38	0.0366
		>50	33/66 (50)

LLN: lower limit of normal; OR: odds ratio.

Analysis is restricted to patients with an ALC  ≥ 0.91 × 10⁹/l at baseline. Exact logistic regression analysis methods applied; p-values are from exact conditional tests. For categorical predictor variables, the first category is the reference category.

^aThe OR is the increase in odds of having an event with an increase in baseline ALC of 1.0 × 10⁹/l.

^bThe p-value evaluates the association between ALC <LLN at the timepoint and each predictor variable.
