“…Sixty‐eight studies were removed after full‐text retrieval for a variety of reasons including study protocol [Hannemann et al, 2011], non‐randomized controlled trials [Wang et al, 2005; Abdelrahim et al, 2011; Assiotis et al, 2012; Yang et al, 2012; Li, 2013; Qian, 2014; Xie et al, 2014], not relevant to fractures [Grote et al, 2007; Elsisi et al, 2015], or not relevant to effect of PEMF [Scott and King, 1994; Linovitz et al, 2002; Kerr‐Valentic et al, 2003; Hannemann et al, 2015]. Moreover, three [Madronero et al, 1988; Gupta et al, 2009; Boyette and Herrera‐Soto, 2012] were excluded because of the lack of a control group. Finally, 22 trials ( n = 1,468 participants) met our eligibility criteria for systematic review and quantitative synthesis.…”
