qPCR analysis of VEGF expression in the synovial membranes (SMs) of knee osteoarthritis (KOA) patients according to their VAS score. a “Box and whisker” plot of VEGF expression in the SMs of KOA patients with mild/moderate (VAS < 6) (n = 44) and strong/severe pain (VAS ≥ 6) (n = 58). The plot shows the median values (bold horizontal line), interquartile range (IQR) (box), and range. Outliers beyond 1.5-fold of the IQR from the box are plotted. * P = 0.008. VAS, visual analog scale. b Scatter plot showing the correlation between VAS scores and VEGF levels. Relative expression was calculated based on the mean of all samples of the VAS < 6 group
