Statically Analysis:
The classification of the uterine cavity was decided with “consensus
rate 60 %” which is described as at least 6 of 10 evaluators agreed on
consensus on shape of the cavity.
The distribution of data was assessed with histograms. Depending on
distribution characteristics, continuous variables were defined with
mean (standard deviation) or median (25th and
75th percentiles). Categorical variables were defined
as percentages. One-way analysis of variance (ANOVA), Student T test,
Mann Whitney U test or chi-square test and its derivatives were used for
between group comparisons. A two tailed p value < 0.05 was
considered as statistically significant. Spearman and Pearson
correlation analysis was used to determine any correlation between
variables.
