  2. Abbreviations: OR, odds ratio; 95% CI, 95% confidence interval; P, P-value; SNAP, IDEXX SNAP® Giardia; Ref, reference group
  3. Notes: OR adjusted for dog population, age, sex, neuter status, fecal consistency score and clustering. Giardia positive: positive with at least one of the three tests. OR in bold: significant association (P < 0.05)
