	Preoperative leakage during reduction testing	Postoperative	SUI	Sensitivity	Specificity	PPV	NPV
		Na	%	%	%	%	%
All methods	Leakage	22/60	37	33	83	37	80
	No leakage	45/227	20
Pessary	Leakage	1/3	33	11	94	33	78
	No leakage	8/37	22
Manual	Leakage	5/11	45	28	86	45	74
	No leakage	13/50	26
Swab	Leakage	5/18	28	29	80	28	81
	No leakage	12/63	19
Forceps	Leakage	3/13	23	38	76	23	86
	No leakage	5/36	14
Speculum	Leakage	8/15	53	53	83	53	83
	No leakage	7/41	17

PPV Positive predictive value, NPV negative predictive value

^aThere were two attempts at prolapse reduction stress testing per subject.
