The Role of NK Cells in the Control of Viral Infection in HTLV-1 Carriers

Table 1

Demographic features and proviral load in HTLV-1 carriers and patients with HAM/TSP.

	Seronegative individuals (SN) ()	HTLV-1 carriers (HC) ()	HAM/TSP ()	value
Age (years)	30 (23-45)	52 (31-69)	63 (36-76)	<0.0001^a,b
Gender (M/F)	1/9	8/12	9/10	0.12
Proviral load (copies/10^6cells)	Not applicable	16,190 (110-292,916)	72,438 (20,000-365,075)	<0.0001

Kruskal-Wallis test with Dunn’s test (^aHC × SN, ^bHAM/TSP × HC); chi-square (); Mann-Whitney test. Proviral load is represented by median (minimal and maximal values).
