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.
