  1. Percentage of measurements with stable or unstable reading, which were done using K-file sizes #10–80 and 1.5 mm SAF file in all three enlargement groups.
  2. Note: Values in the same row and sub-table not sharing the same superscript (i.e., a or b) are significantly different at p < 0.05 in the two-sided test of equality for column proportions. Tests assume equal variances.2 Tests are adjusted for all pairwise comparisons within a row of each innermost sub-table using the Bonferroni correction.2
