Fig. 1From: Validation of an automated sample preparation module directly connected to LC-MS/MS (CLAM-LC-MS/MS system) and comparison with conventional immunoassays for quantitation of tacrolimus and cyclosporin A in a clinical settingPassing-Bablok correlations between the CLAM-LC-MS/MS and immunoassays. a) Tacrolimus (n = 223). b) Cyclosporin A (n = 76). The regression lines are shown as solid lines, and the 95% confidence limits are shown as dashed lines. The dotted lines are the lines of identityBack to article page
