From: Angiogenic gene expression and vascular density are reflected in ultrasonographic features of synovitis in early rheumatoid arthritis: an observational study

Figure 2

There was no significant variation of ultrasound, vascular area and gene expression between each region of the supra-patella pouch (SPP). (A) TNF-α expression by each region of interest within the SPP (Kruskal-Wallis test, P = 0.31). (B) Quantitative power Doppler area (PQuant) (pixels) by each region of interest within the SPP (Kruskal-Wallis test, P = 0.27). (C) Synovial thickness quantitative area (SQuant) (pixels) by each region of interest within the SPP (Kruskal-Wallis test, P = 0.19). (D) Synovial vascular area/mm2 by each region of interest within the SPP (Kruskal-Wallis test, P = 0.09). (E) PQuant/SQuant ratio by each region of interest within the SPP (Kruskal-Wallis test, P = 0.44).
