Case Control Sample size Rmk
Berard - Fluconazole, 2019 Canada
1998 - 2015

Pregnancies not ending in spontaneous abortion or stillbirth (random sampling control) or major malformations (all live-births used as controls). 29458 / 291410 Results (low dose versus unexposed; high dose versus unexposed) were meta-analysed to obtained data whatever dose.
