Additional file 2: Figure S1. of Structure and functional impact of seed region variant in MIR-499 gene family in bronchial asthma

Principal components analysis of asthmatic patients. Ordination plot constructed using 211 patients strand and 20 clinical and laboratory variables. Samples are distributed along two axes. Axis 1 explains 22.6% of variance among patients, whereas axis 2 resolves 11.3% of variance. Samples are scattered and colored according to their genotype; AA (red), AG (green), and GG (blue).
