Data analysis
Data were analyzed using the Statistical Package for the Social Science (SPSS) version 22 (SPSS Inc., Chicago, IL, USA). The quantitative variables were described using mean and standard deviation (SD), and the qualitative variables were described using frequency and percentages. Pearson’s χ2 test was used to determine the relationship between adherence level to treatment and selected variables. Correlation testing exploring associations between the different variables was identified using Pearson’s correlation and Pearson’s χ2 test for significance. A probability value of < 0.05 was considered to be statistically significant for all analysis tests.
