1. OR odds ratio
2. * significantly different from reference group (p < 0.05)
3. a <3 months recall is the reference group
4. b Odds ratios were adjusted for: year of death, season (wet/dry), age, education, nationality and place of death. Only in the neonatal group, age was excluded from the model
