Relationship between G6PD deficiency and gender, age, ethnic group, hematocrit, oxygen saturation, heart rate, tea-colored urine and scleral icterus.

*RE is the random effect of family. Note: The backward elimination results are not shown in this table. The odds of being G6PD deficient were 3.6 times higher in males than in females (p<0.0001). The odds of being G6PD deficient were 0.38 times as high in Igbo children compared to Yoruba children (p = 0.0500). The odds for Igede and Tiv children were not significantly different from Yoruba children (p = 0.7528 and 0.9789 respectively). The odds of being G6PD deficient were 2.1 times higher in children with scleral icterus than those without (p = 0.0351). The magnitude of the scleral icterus effect appeared to be lower if these children also reported tea-colored urine, but the number of children reporting both conditions (N = 10) is too small to be certain.
