Figure 6:

Normalized anesthesia estimates: The estimated difference in FA, MD, RD, or AD per single anesthesia exposure (the average magnitude of a singular anesthesia dose was used). The estimated difference in FA, MD, RD, or AD is normalized as a percentage of the final model’s respective FA, MD, RD, or AD value at 1,095 days (3 years of age) with no anesthesia exposures. Noteworthy, each diffusion property has its range for the colormap in the left column, FA decreases, and MD, RD, and AD increase. Normalized anesthesia p-values: The p-values of the normalized anesthesia covariate. Tracts that do not meet the α = 0.05 significance level appear in light gray
