Assessment of different continence definitions in the context of the randomized multicenter prospective LAP-01 trial—Does the best definition change over time?

Table 2 Agreement between the different criteria and subjective continence at 3, 6 and 12 months measured by Krippendorff’s Alpha

Criterion	Subjective perception of continence^a
	Krippendorff's Alpha [95% CI]
	3 months	6 months	12 months
0 pads	0.63 [0.46, 0.80]	0.69 [0.54, 0.82]	0.70 [0.54, 0.83]
0-safety pad	0.70 [0.55, 0.84]	0.62 [0.46, 0,80]	0.65 [0.47, 0.81]
0–1 pad	0.37 [0.20, 0.56]	0.31 [0.09, 0.51]	0.32 [0.07, 0.55]
ICIQ-SF sum score^b	− 0.79 [− 0.89, − 0.69]^c	− 0.69 [− 0.79, − 0.58]^c	− 0.59 [− 0.70, − 0.49]^c

^aAccording to the question "Do you suffer from incontinence? (yes/no)"
^bICIQ-SF sum score = Q1 + Q2 + Q3 (Avery et al.)
^cKrippendorff's alpha can be used on ordinal variables. In this case, the more negative the values, the more continence is associated with a low score on the analog scale. If all continent subjects reported a 0 and all incontinent subjects reported higher values, we would have the ideal of − 1
