Statistical Analysis
REGRESSION, DISEASE CHARACTERISTIC
A Cohen effect size of 0.2 to 0.5 has been validated in published literature as meaningful difference between control and intervention.Patient demographic, clinicopathologic, and disease characteristics were reported as numbers and percentages. We used a significance threshold of .05 in all analyses. Univariate analysis was performed using Pearson χThe match proportion between the patient’s stated preference with the actual surgery received (coded as match if lumpectomy was preferred and received or mastectomy preferred and received; coded as mismatch otherwise) was calculated to understand whether preference match was higher in any 1 of the 3 groups. We also ran univariate and multivariate regression analyses to study the effect of Navya-PPT on DCS score stratified by other psychological indices. All analyses were conducted through SPSS version 25 (IBM). Data were analyzed from January to June 2020.
