  1. aThe comparison P values refer to the spatial analysis cases with geocodes versus the excluded cases without the village-level (aldea) geocodes. bIn the initial study period, geocodes were at times limited to the municipality-level, without village-level data
  2. aH. pylori and CagA multiplex assay data were not available for all subjects in the study populations
