(available online only). Agreement between different calibration approaches in 943 serum samples from the Collaborative Perinatal Project: GCSF concentration in picograms per millileter.

The top panels show linear RC models for collapsed compared with batch-specific fixed effects models (panel a) and compared with mixed models (panel b). The bottom panels show curvilinear IRC models for collapsed compared with batch-specific fixed-effects models (panel c) and compared with mixed models (panel d). The solid diagonal line reflects perfect agreement.
