Relationship between Painful Crisis and Serum Zinc Level in Children with Sickle Cell Anaemia

Table 2

Relationship between zinc content of 24-hour dietary recall and mean serum zinc level.

Zinc content of meal	Mean serum zinc concentration g/dL (± SD)				-value
	Genotype AA	Sickle cell anaemia
		Steady state	Painful crisis
Low	45.0	30.7 (12.1)	33.9 (20.7)		.8
Moderate	41.1 (17.2)	40.8 (14.0)	24.8 (10.5)	18.4	.000
High	43.3 (12.5)	37.6 (13.7)	28.5 (11.4)	9.9	.000

Only one subject in the control group had low zinc item and was removed from the statistical analysis; therefore, student -test was used to compare the mean zinc level between sickle cell anaemia subjects in steady state and painful crisis in the first row.
