Abstract

Objectives The aim of this study was to perform a comprehensive meta-analysis comparing all therapeutic modalities for intermittent claudication (IC), including best medical therapy (BMT) alone, percutaneous angioplasty (PTA), supervised exercise therapy (SET), and PTA combined with SET, to establish the optimal first-line treatment for IC.Background IC is a common health problem that limits physical activity, results in decreased quality of life (QoL) and is associated with poor cardiovascular outcomes. Previous meta-analyses have attempted to combine data from randomized trials; however, none have combined data from all possible treatment combinations or synthesized QoL outcomes.Methods Following a systematic review of the published research (conducted in December 2018) that identified 37 published randomized trials, a network meta-analysis was performed combining all possible IC treatment strategies.Results Overall, 2,983 patients with IC were included (mean weighted age 68 years, 54.5% men). Comparisons were performed between BMT (n = 688, 28 arms) versus SET (n = 1,189, 35 arms) versus PTA (n = 511, 12 arms) versus PTA plus SET (n = 395, 8 arms). Mean weighted follow-up was 12 months (95% confidence interval: 9 to 23 months). Compared with BMT alone, PTA plus SET outperformed other treatment strategies, with a maximum walking distance gain of 290 m (95% credible interval: 180 to 390 m; p < 0.001). A variety of QoL assessments using validated tools were reported in 15 trials; PTA plus SET was superior to other treatments (Cohen's D = 1.8; 95% credible interval: 0.21 to 3.4).Conclusions In addition to BMT, PTA combined with SET seems to be the optimal first-line treatment strategy for IC in terms of maximum walking distance and QoL improvement.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
