Fig. 2: Fitted profiles for measles antibody concentrations among children with the first dose of MCV at 8 months.

A Observed and B predicted log-transformed geometric mean concentrations. The points in A refer to the log-transformed geometric mean concentrations. The thick curve in B is the predicted mean values of log-transformed concentrations from a generalized additive mixed model. Error bars and shaded areas show 95% confidence intervals. Horizontal red dashed lines refer to a protective threshold of 200 mIU/ml. In the bottom panel, the letter N refer to the sample size used to derive the error bars and shaded areas.
