  4. 4p-value after log-transformation of corrected ferritin concentrations
  5. 1Nutritional parameters were all measured prior to conception from women that were recruited pre-conceptively and were enrolled in the pregnancy study. A correction factor of 0.67 was applied to ferritin if CRP > 0.5mg/L at the time of measurement. BMI = body mass index
