3.1. Baseline characteristics of subjects
A total of 84 subjects were collected and divided evenly between control and intervention groups. The two groups were not significantly different at baseline (Table 1). Ten subjects did not complete the study during the six-month period. Five subjects were unavailable for data collection and one withdrew following a transfer to another hospital. Four subjects were excluded due to lost questionnaires or insufficiently completed diaries. However, no differences were found between those who dropped out of the study.
