Body composition change after high-intensity interval training and rheumatoid arthritis medication use

	Increased lean mass (%)	Decreased fat mass (%)
Medication use
TNFi	3/4 (75.0%)	0/4 (0.0%)
Tofacitinib	1/1 (100.0%)	1/1 (100.0%)
Methotrexate	4/6 (66.7%)	3/6 (50.0%)
Leflunomide	1/1 (100.0%)	0/1 (0.0%)
Sulfasalazine	1/2 (50.0%)	1/2 (50.0%)
Hydroxychloroquine	1/4 (25.0%)	0/4 (0.0%)
NSAIDs	5/8 (62.5%)	2/8 (25.0%)
Prednisone	3/3 (100.0%)	1/3 (33.3%)

Subjects were identified as achieving increased lean mass if their absolute change in lean mass (kilograms) was greater than zero following exercise training. Subjects were identified as achieving decreased fat mass if their absolute change in fat mass (kilograms) was less than zero following exercise training. Medication use was identified on the basis of whether subjects were taking those medications for the duration of the exercise-training program.
