Table 3. Results of topological constraints and hypotheses testing using the AU test.

Partition	Topological Constraint	P AU test
1 (nt 4468–5787)	(SSEV, (LIV, W-TBE))	<0.01
2 (nt 5788–5991)	((SSEV, LIV), W-TBE)	0.025
3 (nt 5992–6333)	(SSEV, (LIV, W-TBE))	<0.01

P-value <0.05 indicates rejection or the alternative constrained hypothesis under the AU test.
