  2. #Values obtained from only 6 samples
  3. *Values obtained from only 7 samples; yrs, years
  4. ap is the p value for comparisons between Ewim, Simiw and Obom
  5. bp is for comparisons between pregnant and non-pregnant women aged between 18 and 40 years old. Data from 4 pregnant women who were not within the 18 and 40 years old age range were excluded from the analysis of pregnant women. The values in the table are presented as medians (interquartile ranges)
