Biomarker heatmaps for significant differences between baseline and week 4 for test and training datasets. Heatmaps representing biomarkers that were significantly different between baseline and week 4 for any of the treatment group for the training (a) and test (b) datasets. In the test dataset, only patients treated with golimumab were evaluated. Colors represent ranges of mean log2 transformed biomarker levels at each time point (see legend for ranges).
