| * Analysis of the final results using the Student’s t-test for dependent samples; ** means improvement after surgery. SD – standard deviation; PFWD – pain free walking distance; MCD – maximal claudication distance; ABI – ankle-brachial index; ICQ – intermittent claudication questionnaire; Q1 – quartile 1; Q3 – quartile 3. | ||||
