Shawki 2018.

Methods	RCT
Participants	Women undergoing first ICSI
Interventions	Study group: endometrial scratch was done in luteal phase of the cycle prior to controlled ovarian hyper stimulation using endometrial bunch biopsy forceps through office hysteroscopy using vaginoscopic approach. Control group: unclear
Outcomes	Ongoing pregnancy, clinical pregnancy, multiple pregnancy, miscarriage stated as captured but only percentages supplied for the outcome of ongoing pregnancy (not defined).
Notes	Described as quote: "Randomized controlled trial" however methods are described in the present tense e.g. "half will undergo an endometrial scratch" additionally the phrasing makes it unclear whether the study was truly randomised e.g. quote: "There were 150 subjects who were undergoing their first IVF cycle only 80 (53.3%) subjects who had undergo for scratching." Unclear if truly RCT. Note: same authoring team as Youssef 2018; appearing in same conference proceedings.
