And yes, the subset of women that choose to take Vitamin D are almost certainly not representative of the population. That said, there was a treatment and a placebo group who thought they were taking Vitamin D, so by comparing those two groups we can start to see the effect of Vitamin D.
In this case 65.6 vs 57.9 giving a relative risk between 1.02 and 1.25. 1.02 > 1, so my reading is that the Vitamin D resulted in a statistically significant decrease in relative risk. That's very exciting.
Why does it work? Would this also apply to the general population? There are plenty of good follow-up questions.

Reply to comment by SaltZookeepergame691 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
Absolutely.
