The HBET group did not show improvement in MWD/T compared with the WA group ( SMD 0.30 , 95 % CI -0.45 to 1.05 ; P = 0.43 ; moderate- quality evidence ) .Compared with HBET , SET was more beneficial for PFWD/T but had no effect on quality of life parameters nor on self-reported functional impairment .
Compared with WA , SET was more beneficial for PFWD/T and self-reported functional impairment , as well as for some quality of life parameters ( e.g. , physical functioning , pain , and physical component summary after 12 months ) , and HBET had no effect .
Data show no obvious effects on mortality rates .
Evidence of moderate and high quality shows that SET provides an important benefit for treadmill-measured walking distance ( MWD and PFWD ) compared with HBET and WA , respectively .
Although its clinical relevance has not been definitively demonstrated , this benefit translates to increased MWD of 120 and 210 meters after three months in SET groups .
These increased walking distances are likely to have a positive impact on the lives of patients with IC .
Data provide no clear evidence of a difference between HBET and WA .
Trials show no clear differences in quality of life parameters nor in self-reported functional impairment between SET and HBET .
BACKGROUND Although supervised exercise therapy ( SET ) provides significant symptomatic benefit for patients with intermittent claudication ( IC ) , it remains an underutilized tool .
Widespread implementation of SET is restricted by lack of facilities and funding .
Structured home-based exercise therapy ( HBET ) with an observation component ( e.g. , exercise logbooks , pedometers ) and just walking advice ( WA ) are alternatives to SET .

OBJECTIVES The primary objective was to provide an accurate overview of studies evaluating effects of SET programs , HBET programs , and WA on maximal treadmill walking distance or time ( MWD/T ) for patients with IC .
Secondary objectives were to evaluate effects of SET , HBET , and WA on pain-free treadmill walking distance or time ( PFWD/T ) , quality of life , and self-reported functional impairment .
Predictors of treatment outcome in intermittent claudication.
OBJECTIVE To derive formulae to predict the likely 12-month health-related quality of life outcome following different treatments for intermittent claudication ( IC ) . DESIGN A prospect i ve , r and omized , controlled study . MATERIAL S One hundred and seventy-one unselected patients with stable IC were sequentially r and omized to invasive therapy , supervised physical training or observation . Hierarchical analysis was used to identify significant predictors of outcome . RESULTS The strongest outcome predictors were baseline values of the respective outcome variables in all groups . No more than two significant secondary predictors were identified for each outcome variable and no outcome variable was a predictor of any other outcome variable . Result ing prediction equations achieved between 61 and 90 % concordance with improvement ( 75 % considered adequate ) , with best prediction for invasive therapy and poorest for observation . Suggested cutpoints for the various endpoints in the three groups had sensitivities ranging between 65 and 100 % and false positive rates between 5 and 50 % . CONCLUSIONS The derived equations adequately predicted improvement on the various outcome variables in invasive therapy and supervised physical training , and may serve as aids in selecting patients likely to benefit most from a particular treatment strategy . The uniqueness of the outcome variables underscores the importance of implementing a comprehensive set of endpoints relevant to the impacts of the condition
