  1. 1Variables that were explored but did not enter the linear regression model for CRP (nmol/L) in lactation (P > 0.15): Weeks post-partum, BMI (kg/m2), wood smoke (h/d), presence of caries, score of vaginal Lactobacillus, Bactaroides/Gardnerella, T.vaginalis, yeast and diplococcal infection, vitamin B12 < 150 pmol/L, vitamin D < 50 nmol/L
  2. 2Variables that were explored but did not enter the logistic regression model for elevated CRP in lactation (P > 0.15): Weeks post-partum, wood smoke exposure (h/d), fieldwork (h/d) presence of caries, score of vaginal Lactobacillus, Bacteroides/Gardnerella, Mobiluncus, yeast and diplcoccal infection, folic acid < 10 nmol/L, vitamin B12 < 150 pmol/L, vitamin A < 1.05 μmol/L, vitamin A > 1.5 μmol/L, vitamin D < 50 nmol/L
