Statistical Method
SPSS 26.0 (IBM Corporation, Armonk, New York, United States) program was
used in the analysis of variables. The compliance of nonparametric
variables to normal distribution was evaluated using the Shapiro-Wilk
francia test. Mann-Whitney U test was used together with Monte Carlo
simulation results in comparing the two independent groups according to
quantitative data. In the comparison of categorical variables, Pearson
Chi-Square test, Fisher exact test and Monte Carlo Simulation technique
were tested and column ratios were compared and expressed according to
Benjamini-Hochberg corrected p-value results. Odds ratio was used with
95% confidence intervals to show how many times more risky those with a
risk factor were compared to those who did not. Sensitivity and
specificity ratios for the relationship between the classification
separated by the cut-off value calculated according to the variables of
the groups and the actual classification were expressed by ROC (Receiver
Operating Curve) analysis. Kappa statistics were used to evaluate the
correlation between PCR and rapid antibody test and CT methods.
Quantitative variables were expressed as mean ± SD (standard deviation)
and Median (Minimum / Maximum) in the tables, while categorical
variables were shown as n (%). Variables were examined at a 95%
confidence level, and a p-value of less than 0.05 was considered
significant.
