Note. Small, medium, and large effect sizes are annotated in bold in the table. Other effect sizes were found to be smaller than small effect size. The mean absolute change in this table can be different than the difference of the means that are reported in Table 6. This difference can be explained by missing data at follow-up in HF self-care measurement and by missing data in some of the items of health status measurement, as well as by the small sample size
^aSmall effect size ≥ 0.2
^bmedium effect size ≥0.5
^clarge effect size ≥ 0.8
