Figure 2
The vertical axis of the graph is labeled “Morbidity”, and the horizontal axis is labeled “Age (years)” and ranges from 50 to 90 in increments of 10 units. A baseline is shown arising from age 50, slightly above the origin of the vertical axis, and steadily rising toward the top right. Superimposed on this baseline are five peaks in morbidity, each shaped like a tall, narrow triangular spike. The first spike appears at the age of 55 and is labeled “Forearm fracture”. Further forward, three sharp peaks correspond to “Vertebral fracture”, shown between the ages of 60 to 75. As the three curves form left to right, the peaks are shown much larger, and a higher spike appears. At the age of 82, the largest and highest spike is shown and is labeled “Hip fracture”, with the highest morbidity. On the right of the graph, two vertically aligned arrows are shown. The vertical arrow at the bottom is shown with a text box labeled “Morbidity related to ageing”, shown below the baseline. The arrow at the top is labeled “Morbidity related to fracture”, shown corresponding above the baseline, and above the middle length of the morbidity. Note: All numerical data values are approximated.Fragility fracture life-course by Kanis and Johnell (1999)
