Figure 1From: Utilization of routinely collected administrative data in monitoring the incidence of aging dependent hip fractureProbability of having a preceding hip fracture as a function of backward time in months from the first fracture in 1998–2002. The smaller picture is a tenfold magnification of the final months. Dotted curves represent the expected probabilities of having a hip fracture (upper curve is calculated with a one-year clearance period and the lower curve with a ten-year clearance period, see text for more information).Back to article page
