Reply to comment by SelarDorr in Analysis showed that 65.6% of women who took extra Vitamin D gave birth naturally. The study analysed results from the MAVIDOS trial which involved 965 women being randomly allocated an extra 1,000 International Units (IU) per day of vitamin D during their pregnancy or a placebo. by Wagamaga

This is a post hoc analysis. This was NOT a named secondary! It explicitly says so in the paper, and it’s why I explicitly said it was a post hoc analysis…

For your info, from the reg record:

>Primary outcome measure

>Neonatal whole body bone area, bone mineral content and bone mineral density assessed by dual energy x-ray absorptiometry (DXA) within 10 days of birth.

>Secondary outcome measures

>1. Neonatal and childhood anthropometry and body composition (weight, length and skinfold thickness measurements), assessed within 48 hours of birth

>2. Women's attitude to pregnancy vitamin D supplementation (qualitative study; assessed in main study only). Methodology and timepoints of assessment not yet defined as of 03/03/2008

>3. Childhood bone mass at 4 years
