  1. Detailed cohort characteristics (exposures and FFQ) can be found in Supplementary Dataset 1.
  2. *p < 0.05 CD vs. Ctl in Israel; ^p < 0.05 CD vs. Ctl in urban China; #p < 0.05 Rural vs. Urban. Most analyses were done within the rural population after we stratified subjects living in a rural area to those spending <50% of their time in the last year in urban areas (“rural”, n = 88) and compared them to those living in a rural area but spending ≥50% of their time in an urban environment (“rural-urban”, n = 74), and were adjusting for age in the indicated analyses.
