DCIS = ductal carcinoma in situ; HADS = hospital anxiety and depression scale; IQR = interquartile range.
NCol = column percent and shows the proportion of observations in each row from among those in the column.
Percentages do not always add up to 100 % due to rounding.
a
High proportion of missing as data collection from electronic patient records had not yet been completed at the time of data extraction.
b
P-value based on Chi-square, Fisher's exact or Mann-Whitney test as appropriate; p-value ≤0.05 considered significant. The p-values were adjusted for multiple comparisons using the Benjamini-Hochberg procedure to control the false discovery rate.
