Fig. 3: Stable [¹¹C]PBR28 SUVR in ASD and CON.

A Correlation plots show that [¹¹C]PBR28 SUVR over a mean rescan interval of 4.6 months are highly correlated in ASD (N = 4) and CON (N = 5). Each dot represents the mean [¹¹C]PBR28 SUVR in a brain region and the lines indicate the standard deviation. The dotted line represents the identity line. B Bland–Altman plots of between-scan agreement. Mean [¹¹C]PBR28 SUVR values were normalized to a range of 1–2 in ASD and CON. The solid line represents the mean percent difference between scan 1 and scan 2, and points represent each ROI from each participant. The upper and lower limits of agreement are depicted with dotted lines and the shaded regions are the 95% confidence interval of the upper and lower limits of agreement. SUVR standardized uptake value ratio, ASD autism spectrum disorder, CON control, N number, ROI region of interest.
