*Student’s t-test.
**For LA, the OR is for a 1 μmol/ml increase in concentration. All other omega fatty acid variables were multiplied by 100 and therefore the fecundability ratio represents a 1/100 μmol/ml change in concentration.
OR, odds ratio.
Due to using inverse probability weighting, the 95% CIs were calculated using robust variance.
