Table 2: Relationship between zinc content of 24-hour dietary recall and mean serum zinc level.

High43.3 (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.
