Table 3 Stool patterns identified by factorial analysis using the 5-stool status

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. The values are expressed as factor load with the varimax rotation. Bolded values are stable factor load scores (≥0.4). The stool status was evaluated by each category as follows: stool frequency [1 point (2 or less times per week) to 6 points (7 or more times per week)], stool volume [1 point (smaller) to 8 points (larger)], stool color [1 point (yellow) to 6 points (dark)], stool shape [1 (severe constipation; separate hard lumps) to 7 (severe diarrhea; liquid consistency with no solid pieces)], and stool odor [1 (no smell) to 4 (severe smell)]
