Notes	Registration was done retrospectively, and the current status states that recruitment is complete. We contacted the study authors (14 February 2019) to clarify what their control group treatment consisted of. However, from the 3 emails sent to the available email addresses, only 1 email was delivered (f.farokhi@arakmu.ac.ir). We received no response. We contacted study authors again (24 Novemeber 2022) to clarify the status of the study. Again, the emails failed to deliver. We await publication of this study to assess its eligibility for this review.
