Top scoring networks derived from the proteins with different abundance (≥1.2-FC) at Stage II compared to Stage I of the autologous chondrocyte implantation (ACI) procedure in those who responded well clinically (responders; a) and those who did not respond clinically (non-responders; b). Red nodes represent greater protein abundance at Stage II of ACI; green nodes represent lower protein abundance at Stage II of ACI; and white nodes represent inferred proteins which are not differentially expressed between Stage I and Stage II (based on label-free quantification proteomic analysis). The key to the features within the network is shown.
