“…The current update identified 8 trials: 5 from Iran ( Taheri et al, 2015 ; Zarrin et al, 2017 ; Kamelian et al, 2017 ; Jozanikohan and Kazemi Saleh, 2015 ; Mohammad-Alizadeh-Charandabi et al, 2015 ), 1 from Egypt ( Shehata, 2016 ), one from occupied Palestine/Israel ( Tepper et al, 2016 ), and one from Lebanon ( El-Hajj Fuleihan et al, 2016 ; Rahme et al, 2017 ). The latter was included in our previous review ( Chakhtoura et al, 2017a ), since we had access to primary data, but it was not published then, and is described herein ( Table 1 ) ( El-Hajj Fuleihan et al, 2016 ; Taheri et al, 2015 ; Tepper et al, 2016 ; Zarrin et al, 2017 ; Kamelian et al, 2017 ).…”

The risk of bias in the included trials was unclear ( Taheri et al, 2015 ; Tepper et al, 2016 ; Kamelian et al, 2017 ; Jozanikohan and Kazemi Saleh, 2015 ) to high ( Zarrin et al, 2017 ; Mohammad-Alizadeh-Charandabi et al, 2015 ), with the exception of 2 RCTs considered at low risk of bias ( El-Hajj Fuleihan et al, 2016 ; Shehata, 2016 ). Three studies were conducted exclusively in women ( Taheri et al, 2015 ; Mohammad-Alizadeh-Charandabi et al, 2015 ; Shehata, 2016 ), one study exclusively in men ( Tepper et al, 2016 ) and the others included both genders ( El-Hajj Fuleihan et al, 2016 ; Zarrin et al, 2017 ; Kamelian et al, 2017 ; Jozanikohan and Kazemi Saleh, 2015 ).…”
