Parathormone Levels in a Middle-Eastern Healthy Population Using 2^nd and 3^rd Generation PTH Assays

Figure 3

Scatterplot showing the correlation between log(2^nd generation PTH) (Ln (PTH 2G)) values and log(3^rd generation PTH) (Ln (PTH 3G)) values. The dashed lines represent 95% confidence limits for correlation. The (1  x) line represents the line of perfect concordance (that is, y = x, where Lin’s coefficient equals 1).
