Primary Hyperparathyroidism in Older People: Surgical Treatment with Minimally Invasive Approaches and Outcome

Figure 1

Box plot regarding age. It represents the distribution by age of pHPT in our elderly cohort made up of 37 patients during the last 5 years of activity of the Department of General Surgery of University of Trieste. Elderly mean age at time of operation was 76.08 years (range: 70–86 years). The median age was 75 years and corresponds to the dark thickened band near the middle in the box plot, drawn vertically. The box in the figure shows the lower and upper quartiles of age (range 73–78 years) while whiskers show values below the 25th (from 70 to 72 years) and above the 75th (from 79 to 85 years). The upper dot not included between the whiskers means a patient 86 years old at time of operation.
