Analysis of QoL data by SF-36 questionnaire at
baseline compared with three weeks of PR or usual care
revealed that there was a statistically significant
improvement in both the groups of patients at the end
of three weeks. Between-group analysis of data and
delta changes in various domains, however, showed
that the benefit was considerably more in favour of the
intervention group patients who were administered PR
exercises over the usual care provided to the control
group patients (Table 5).
