Table 1.

Prevalence and characteristics of heart murmurs in SB, BB, and Navy dolphins.

	Counts				Prevalence
			Murmur present			Within murmur cases
	n	None	Fixed	Dynamic	Any murmur	Fixed	Dynamic
SB	19	2	7	10	0.89	0.41	0.59
BB	34	4	19	11	0.88	0.63	0.37
					P = 1	P = 0.22
Free-ranging	53	6	26	21	0.89	0.55	0.45
Navy	65	5	9	51	0.92	0.15	0.85
					P = 0.54	P < 0.001

Murmur prevalence was compared between the three populations (Fisher's Exact Test). The sum of SB and BB is provided (free-ranging) for comparison of free-ranging and managed dolphins.
