Table 2.
Univariate correlations and best subsets regression model coefficients for correlations of all parameters with superior/inferior average contact center (S/I CC) and range (S/I Range) for shoulders with intact rotator cuffs (CTL) and shoulders with rotator cuff tears (RCT). HH = humeral head, ROC = radius of curvature, CI = conformity index, SA = stability angle, GI = glenoid inclination.
