Table 2.

Tear characteristics and propagation data separately by cable integrity (N=68).

Variable	Cable Integrity at Baseline		p-value¶
	Intact (n=43)	Disrupted (n=25)
Patient Characteristics
Baseline age (years), mean (SD)	65.5 (8.7)	67.3 (8.6)	0.42
Age at final enlargement (years), mean (SD)	67.2 (8.8)	68.8 (8.6)	0.46
Duration (years) from study enrollment to final enlargement, mean (SD)	4.8 (3.0)	3.6 (2.2)	0.09
Tear Characteristics
Tear width (mm), median [IQR]:
Baseline	8.0 [6.0]	19.0 [11.0]	<0.0001**
Final enlargement	18.0 [11.0]	30.0 [17.0]	n/a
Change†	7.0 [8.0]	9.0 [5.0]	0.18**
Tear distance from biceps (mm), median [IQR]:
Baseline	10.0 [5.0]	0.0 [0.0]	n/a
Final enlargement	6.0 [9.0]	0.0 [0.0]	n/a
Change‡(same as anterior enlargement)	5.0 [9.0]	0.0 [0.0]	n/a
Enlargement Data
Anterior enlargement (mm)‡, median [IQR]	5.0 [9.0]	0.0 [0.0]	n/a
Posterior enlargement (mm)§, median [IQR]	4.0 [7.0]	9.0 [5.0]	n/a
Direction of enlargement of ≥ 3mm, n (%):
Anterior only	16 (37%)	0 (0%)	n/a
Posterior only	16 (37%)	24 (96%)	n/a
Anterior and posterior	11 (26%)	1 (4%)	n/a

SD = standard deviation; IQR = interquartile range; n = number of patients; n/a = analysis not performed; mm = millimeters

^†Calculated as: (width_final - width_baseline).

^‡Anterior enlargement is defined as the change in tear distance from biceps between Baseline and the final enlargement event (distance_baseline - distance_final).

^§Posterior enlargement is defined as the change in tear width minus the anterior enlargement between Baseline and the final enlargement event [(width_final - width_baseline) - (distance_baseline - distance_final)].

^¶P-value compares tears with the cable-intact versus disrupted by analysis of variance.
