And the Pittsburgh Sleep Quality Index (PSQI) which had 7 different dimensions, including subjective sleep quality[p = 0.001 < 0.05], sleep latency, sleep duration[p = 0.000 < 0.05], habitual SE[p = 0.000 < 0.05], sleep disorders[p = 0.002 < 0.05], use of sleep medications[p = 0.000 < 0.05], and daytime dysfunction[p = 0.000 < 0.05], showed a higher scores in the trial group than the one in the control group in every dimension. The final results of the total scores in PSQI also showed a higher scores in trial group with a p = 0.000 < 0.05 (Test of WMD), suggest a statistically significant difference. While the adverse effects showed a lower rate in the trial group than the one in the control group under a fixed-effect model, with a p = 0.000 < 0.05, indicate a statistically significant difference.
