Additional file 7 of Single nucleotide polymorphism genes and mitochondrial DNA haplogroups as biomarkers for early prediction of knee osteoarthritis structural progressors: use of supervised machine learning classifiers

Additional file 7: Figure S4. Ten-fold cross-validation of the M32-3 and MH17 models. Validation of the model a) M32-3 (age, bone mass index [BMI], TP63, DUS4L, GDF5, FTO) and b) MH17 (age, BMI, mtDNA haplogroup, FTO, SUPT3H) was done using the ten-fold cross-validation (k-fold) methodology, as described in the Methods section and Additional file 4.
