Figure 4

Association between the volume of the rehabilitation unit and maintainability among Finnish hip fracture patients aged 65 years and older who lived at home before the fracture in 1998-2001. The x-axis represents the volume of the pooled number of treated hip fracture patients in a rehabilitation unit during 1998-2001 in Finland, and the y-axis contains the four-month risk-adjusted unsuccessful maintainability (death, readmission, or referral to a higher-level hospital). The dots represent rehabilitation units (n = 272). The solid line is the trend from the mean model, the dashed line is the trend from the linear model, and the dotted line is the trend from the spline model. DIC = Deviance Information Criterion
