Patient classifications based on WHO case definitions and fluid intervention

Clinical diagnosis	No IV fluid, less than M+5% (cases (%))	IV fluid + less than M+5% (cases (%))	No IV fluid+M+5% (cases (%))	IV fluid+M+5% (cases (%))	Total (cases)
OFI	526 (88)	37 (6)	33 (5.5)	3 (0.5)	599
	DNRI	DRI	DRI	DRI
DF	224 (85)	28 (10.5)	8 (3)	4 (1.5)	264
DHF	65 (43)	62 (42)	3 (2)	20 (13)	150
DHF grade 1	6 (50)	5 (42)	0 (0)	1 (8)	12
DHF grade 2	59 (46)	51 (40)	3 (2)	15 (12)	128
DHF grade 3	0 (0)	5 (56)	0 (0)	4 (44)	9

Total	815 (81)	127 (12)	44 (4)	27 (3)	1013

Note.-Patients were classified based on the fluid interventions received into 1) did not received any intravenous fluid and the total fluid on any day during hospitalization was below the combined volume of maintenance fluid and 5% deficit (M + 5%), 2) received intravenous fluid but the volume of daily fluid intake was below the volume of M + 5% deficit, 3) did not receive intravenous fluid intervention but fluid intake exceeded the combined volume at least one day during the illness, and 4) received intravenous fluid and the fluid intake exceeded the combined volume at least on day during the illness. Dengue patients in the last three groups were classified as dengue requiring intervention (DRI) in this analysis. The rest of dengue patients were classified as dengue not requiring intervention (DNRI).
