Figure 6. Interlaboratory reproducibility - The results obtained among three laboratories of three blindly tested compounds (denoted as D, E and F) using Support Vector Machine as algorithm, are presented. Red indicates the highest probability of a compound to belong to a specific class (e.g. DMSO control, GTX, NGTX, NC), whereas green indicates the lowest probability that a compound could be classified in the respective group. The experiments were performed in triplicate. (BPI, Biopredic International; HUL, University Hospital of Valencia; VUB, Vrije Universiteit Brussel).
