Table 4 Odds ratios for stool patterns and prevalence of pks+ E. coli carriers

From: Stool pattern is associated with not only the prevalence of tumorigenic bacteria isolated from fecal matter but also plasma and fecal fatty acids in healthy Japanese adults

  1. Ref reference. The prevalence rates of pks+ E. coli are shown as numbers of people and percentages. The detail of the three stool patterns are as follows. Factor 1: lower frequency, darker color, and harder shape; factor 2: higher volume and softer shape; and factor 3: darker color and stronger odor
  2. aStatistical analysis was carried out using the likelihood ratio test for multivariate logistic analysis, and the odds ratios (ORs) and 95% confidence intervals (CI) were estimated. Bold p values are statistically significant (p < 0.05)
  3. bModel 1 was adjusted for age (continuous) and sex (male or female)
  4. cModel 2 was as model 1 plus mutual adjustment for body mass index (continuous), family history of cancer (yes or no), smoking status (never smoker, past smoker, or current smoker), step counts (continuous), alcohol drinker (yes or no), and green tea consumption (continuous)
