    Document: Studies eligible for this systematic review need to meet following criteria: (1) patients diagnosed with ONFH, (2) ESWT was applied to at least part of patients, (3) adequate data were provided to assess the therapeutic effect (e.g., visual analog scores, Harris score, ARCO stage), and (4) the types of included studies contained prospective or retrospective cohort, open label trial, randomized controlled trial, case-control study and case report. If data overlapped in different articles, we only included the most comprehensive or most recent one. Using these predesigned criteria, apparently ineligible articles were first excluded by screening titles and abstracts. The remainders were downloaded and then assessed by scrutinizing the full texts.
