Descriptive Statistics for Blood Folate Obtained at Baseline for Two Groups of Brazilian Women Subsequently Randomized in a Folic Acid Supplementation Trial

Blood folate Before Fortification (N=116) After Fortification (N=240) P-value
Serum folate (nmol/L) 11.2 (4.66) 20.3 (7.90) <0.001
Red blood cell (RBC) folate (nmol/L) 177.6 (92.93) 368.3 (212.12) <0.001

Note: The Table reports summary statistics – means and standard deviations (SD) in parentheses. The summary statistics are based on 356 women had complete data on both serum and RBC folate levels. Group differences in means were evaluated using a t-test.
