The Effect of Neoadjuvant Chemotherapy on Physical Functions

As a result of the power analysis made from the reference study; when the effect size d=0.8, it was calculated that 80% power could be obtained at 95% confidence level when at least 42 people were included in the study. Considering that a lower effect size can also be obtained, it is planned to complete the study with at least 46 participants by taking 10% more participants. The data will be analysed with SPSS 25.0 package programme. Continuous variables will be given as mean ± standard deviation and categorical variables as number and percentage. When parametric test assumptions are met, the Significance Test of the Difference Between Two Means will be used to compare independent group differences; when parametric test assumptions are not met, the Mann-Whitney U test will be used to compare independent group differences. In dependent group comparisons, repeated measures analysis of variance will be used when parametric test assumptions are met; Friedman test will be used when parametric test assumptions are not met. In addition, the relationships between continuous variables will be examined by Spearman or Pearson correlation analyses and the differences between categorical variables will be examined by Chi-square analysis.
