Although the difference between groups did not reach statistical significance ( p = 0.052), the test group showed a numerically greater improvement (See Figure S1B ). 3.3.2.

narrowly missed statistical significancep = 0.052so close (0.05 < p ≤ 0.1)

For example, although the difference in PPD reduction between groups narrowly missed statistical significance ( p = 0.052), the mean reduction was 94.5% greater in the test group compared to the control group (−3.21 mm vs. −1.65 mm), representing a clinically relevant effect that might have reached significance with a larger sample size.

In the test group, the change at 12 months approached significance ( p = 0.057), while no between‐group differences were observed (See Figure S1H ). 3.3.7.
