Fundamental data quality assessment of the OIID. (a) The scatter plot demonstrates the data quality assessment of the T1-weighted structural scan, with each data point representing a participant’s data value. Within the plot, a downward arrow indicates that a lower value corresponds to superior data quality, whereas an upward arrow suggests that a higher value signifies better data quality. \({\rm{\mu }}\) represents the mean brightness of the image, while \({\rm{\sigma }}\) represents the standard deviation. (b) The violin plots showcase the Framewise Displacement (FD) for each participant across all runs. The pink bars, black dots, and error bars lines respectively depict the quartile range, mean, and the minimum and maximum values. Notably, participant motion within the OIID was generally minimal, as indicated by a mean FD well below 0.5 mm for all participants.
