Table 2.

Proportion of participants in the rapid- v. non-rapid-cycling group with treatment-emergent hypomania^a

	Rapid-cycling group (n = 25)		Non-rapid-cycling group (n = 56)
	n	% (95% exact CI)	n	% (95% exact CI)	P b
Hypomania	5	20.0 (6.8–40.7)	5	8.9 (3.0–19.6)	0.27
Type I subsyndromal	5	20.0 (6.8–40.7)	10	17.9 (8.9–30.4)	0.82
Type II subsyndromal	2	8.0 (1.0–26.0)	5	8.9 (3.0–19.6)	0.89
Type III subsyndromal	2	8.0 (1.0–26.0)	13	23.2 (13.0–36.4)	0.13
Hypomania or type I	10	40.0 (21.1–61.3)	15	26.8 (15.8–40.3)	0.30
Hypomania or type I or type II	11	44.0 (24.4–65.1)	18	32.1 (20.3–46.0)	0.33
Hypomania or type I or type II or type III	11	44.0 (24.4–65.1)	26	46.4 (33.0–60.3)	0.99

^aSome patients had more than one subsyndromal episode. Thus, the number of patients experiencing an episode shown in Table 2 may be smaller than the total number of episodes shown in Table 3.
