- All values are shown as numbers of people and percentages and weighted κ statistics with 95% confidence interval (CI). The stool status was evaluated by each category as follows: 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)]. Disagreement was defined as a difference of more than three categories between each variable. The weighted κ statistic can range from 0.00 (perfect disagreement) to 1.00 (perfect agreement)
