Study parameters and result analysis
The average operation time from the first incision to earplug, as well
as entering the hidden area of MESVI expression, the results of
preoperative, intraoperative and postoperative examination are all the
results of the above study.
The above experimental results were statistically analyzed by SPSS
(version 24.0; SPSS Inc, Chicago, Illinois, USA). The average and
standard deviation of digital variables, and the numbers and percentages
of classified variables are used as the summary data of this time. Use
paired t to test paired samples. Chi-square test or Fischer test was
used to accurately check the unpaired proportion comparison. The
experimental standard with statistical significance allows the
difference of P≤0.05.
