Odds ratios (OR), adjusted odds ratios (aOR), 95% confidence intervals (CI) and p values are shown. OR, aOR, CI and p values reported to two decimal places. The term livestock refers to cattle, sheep and/or goats. Consumption practices also refer to products from cattle, sheep or goats. The period of reference for all livestock variables was the previous 12 months.
