To the Editor: We would like to thank Crofts et al [1] for their positive and constructive comments regarding our article [2]. The main reason why we have not explored insulin response in the Danish Inter99 cohort using the latent class trajectory approach is fairly technical. Serum insulin values are usually log-transformed before analysing them as continuous outcomes because of their skewed distributions. In our study, this would mean we would model a piecewise-linear trajectory on the log-scale (Fig. 1a), which results in a rather unrealistic shape when transformed back to the original scale (Fig. 1b). Imposing the peak at 30 min is already a big restriction; therefore, we did not want to put this further constraint on the shape of the insulin response curve.
