Reviewer's report:  
 
Dear author, thank you for investigating this important issue. ı have read with interest. But ı 
wonder about some points and a have some criticism.  
1. In result section page 7 line 3 -5: ''In the pre -menopausal group, 14.9% (29/195) o f patients 
with a PD ≥10 mm on TVUS were normal (Table 3)''. what was the indictions for 
hysterescopy in this group?  
 
2. in all indications you performed hysterescopy. why didn't you choose dilatation and curettage 
or pipelle biopsies for endometrial thick ening? what were the signs in hysteroscopy for 
endometrial thickening especially for endometrial carcinoma and hyperplasia. which methods 
did you perform during hysteroscopy for endometrial thickening? did you perform resection 
all uterine wall or local ti ssue removed by hysteroscopic forceps or by any device?  
 
3. for endometrial thickening group, endometrial hyperplasia or carcinoma could be overlooked 
due to choosing hysteroscopy? ı think we can't generalize cut off thickening 11 or 12 mm, we 
could specul ate the sensitivity and spesifity of diagnostic accuracy of hysteroscopy or cut off 
value of hysteroscopy for thickening if we have d&c control group.  
 
4. material and methods should be detailed
