Age is presented as mean ± SD. Categorical variables are presented as n (%). P-values were calculated by two-sided Wilcoxon ranked sum test for age and Fisher’s exact test for categorical variables. P-values ≤ 0.05 were considered statistically significant.
HF-LED-RL: high fluence light-emitting diode-red light
