  1. LBW: low birth weight; ANC: antenatal care; AOR: adjusted odds ratio; CI: confidence interval; CQ: chloroquine
  2. (*) Odds ratios adjusted for primigravidity and number of ANC visits
  3. (**) P values calculated with the Wald test
  4. (***) Univariate Chi-square test for linear trend: P < 0,001
