2.4. Statistical analysis
Statistical Package Software for Social Science (SPSS) version 18 was
used to analyze the data, and P < 0.05 was considered
statistically significant. Continuous variables were assessed using the
mean and standard deviation, while categorical variables were evaluated
using frequency and percentage. The Analysis of Variance (ANOVA) test
was used to examine the relationship between means of age, time of
cancer diagnosis, hospital admissions, chemotherapy and radiotherapy
sessions, and circadian rhythm types. Furthermore, Fisher’s exact test
was used to determine the relationship between chronotype and gender,
educational level, marital status, patient condition, treatment methods,
occupation, and type of cancer. Kolmogorov-Smirnov analysis was used to
verify the normality of the variable distribution.
