The four randomised controlled trials consisted of one multi‐centre, double‐blind, study (Zitek et al, 2018), one single centre double blind placebo‐controlled study (Gur & Tekin, 2021), one prospective single‐blinded study (Behrbalk et al, 2014) and one prospective controlled study (Shillington et al, 2021). The three non‐randomised studies consisted of one prospective self‐controlled interventional study (Sikka et al, 2019), one controlled experimental study (Parlar Kilic et al, 2015) and one prospective interventional study (Moustafa et al, 2017).…”
