Statistical analysis
Considering the results of the earlier research by Akavipat and his associates [The study used 80% power and 95% significance levels. Statistical Package for Social Sciences (SPSS) version 26 for Windows was utilized to code, process, and analyze the collected data (SPSS Inc, Chicago, IL, USA). [A match-paired t-test was employed to contrast the means of BIS values across each time point. Statistical significance was assigned to the results if the p-value was less than 0.05. Pearson’s correlation and Bland-Altman analysis were performed using Med Calc software for Windows 8.1.0.0 (June 13, 2005). The results were displayed in a Bland Altman plot along with the bias and 95% limit of agreement. Clinically, the acceptable bias ranged from − 5 to 5. The IBM SPSS software program version 20.0 was utilized to examine the data fed into the computer. (Armonk, NY: IBM Corp). The Shapiro-Wilk test was employed to determine the normality of continuous data. For regularly distributed quantitative variables, range (minimum and maximum), mean, and standard deviation were employed to convey quantitative data. Frontal and Post-A were compared utilizing a paired t-test. The significance of the outcomes was assessed at the 5% level.
