TABLE 2.

Overview of the tract labels that show changes in quantitative anisotropy (QA) for the different contrasts used in this analysis.

Contrast	Tract (Atlas: HCP1021) (All data is presented in neuroanatomical convention- Left on Left)	Direction and FDR	QA (Standard Error)
Postflight – Preflight	• Corpus Callosum Forceps Major • Inferior Fronto Occipital Fasciculus, R • Medial Lemniscus, R • Middle Cerebellar Peduncle, Bilateral	INCREASING QA (FDR = 0.0033)	0.28 (± 0.015)
Postflight – Preflight	• Arcuate Fasciculus, L • Corpus Callosum Body • Corpus Callosum Forceps Minor • Corticopontine Tract Parietal, L • Corticospinal Tract, L • Corticostriatal Tract Anterior, R • Corticostriatal Tract Superior, R • Corticostriatal Tract Superior, L • Dentatorubrothalamic Tract, R • Vermis	DECREASING QA (FDR = 0.0009).	0.26 (± 0. 013)
Followup – Postlight	• Anterior Commissure • Cingulum Frontal Parietal, R • Corpus Callosum Body • Corpus Callosum Forceps Minor • Corticostriatal Tract Anterior, R • Corticostriatal Tract Anterior, L • Middle Cerebellar Peduncle Bilateral • Uncinate Fasciculus, L	INCREASING QA (FDR = 0.0567).	0.27 (± 0.014)
Followup – Postlight	• Cingulum Parahippocampal Parietal, R • Corpus Callosum Body • Corpus Callosum Forceps Major • Corpus Callosum Tapetum • Corticostriatal Tract Posterior, R • Corticostriatal Tract Posterior, L • Inferior Longitudinal Fasciculus, R • Thalamic Radiation Posterior, R • Thalamic Radiation Posterior, L	DECREASING QA (FDR = 0.0014)	0.43 (± 0.022)
Followup – Preflight	The connectometry analysis found no significant result in tracks with increased QA.	INCREASING QA (FDR = 1.00)	N/A
Followup – Preflight	• Arcuate Fasciculus, L • Cerebellum, R • Cerebellum, L • Corpus Callosum Body • Corpus Callosum Forceps Major • Corpus Callosum Forceps Minor • Corpus Callosum Tapetum • Corticopontine Tract Parietal, L • Corticospinal Tract, L • Corticostriatal Tract Posterior, L • Medial Lemniscus, L • Middle Cerebellar Peduncle Bilateral • Superior Longitudinal Fasciculus, R • Vermis	DECREASING QA (FDR = 0.0069)	0.36 (± 0.018)

The right column shows the average QA change for all significant tracts of the associated contrast. N/A is used for contrasts where no significant tracts show QA changes. R = right, L = left.
