Statistical Analysis
The analysis of data was processed by SPSS 25.0 statistical software.
Student’s t and Chi-square tests were used for numerical variable
calculation. P <0.05 was considered statistically
significant. We chose 20 patients as the preliminary experimental group
and calculated the sensitivity (Se) and specificity (Sp). To achieve the
value, the sample size required for H-E stain was 58, and for
Papanicolaou stain was 103. Therefore, we collected 180 samples. The
dyeing degree of satisfaction between H-E and Papanicolaou stain were
compared. To compare the diagnostic validity and benefit, we analyzed
the Se, Sp, false positive rate (FPR), false negative rate (FNR),
positive likelihood ratio (LR+), negative likelihood ratio (LR-), Youden
index (r), positive predictive values (PPV), and negative predictive
values (NPV) of H-E and Papanicolaou stain. Cohen’s kappa coefficient
was used to measure the diagnostic consistency of endometrial lesions.
The price and service time of dye, dyeing efficiency, and dyeing time of
them were compared as their cost performance.
