To mitigate this risk without altering the preregistered protocol, interpretations of the secondary ultrasonographic outcomes were conducted with strict caution, conceptually prioritizing highly significant changes ( p ≤ 0.01) as robust findings, while treating borderline significant values (e.g., p = 0.03 or 0.04) with clinical reservation. 3 Results Thirty participants were initially allocated to each group.
