Microarray predictor of response to infliximab in rheumatoid arthritis (RA) patients
Blood RNA from 48 Rheumatoid Arthritis patients was extracted at baseline of anti-TNF alpha treatment with infliximab. From these 44 reached week 14 of treatment at which the clinical response was determined. Using 2/3 of the sample we built a multigene predictor using kNearest-Neighbour algorithm and Leave-One Out cross validation. The remaining 1/3 of the sample was used to estimate the precision accuracy of the predictor model.
