Inferring Colonization order in oral microbiomes

Oral Site	Total	Directed	Red	E→L	E→E orE→L	L→E	Consistent Red edges
Buccal mucosa	69	57	5	1	4	0	100%
keratinized gingiva	39	36	8	3	5	0	100%
Palatine tonsils	126	116	9	1	13	1	92%
Saliva	102	86	8	1	12	0	100%
Subgingival plaque	123	113	8	1	18	0	100%
Supragingival plaque	109	105	11	3	13	1	92%
Dorsum of tongue	56	50	11	1	4	0	100%
Throat	92	83	8	0	9	0	100%
Total	716	646	68	11	78	2	97.4%

The columns indicate the following: sampled oral sites, total number of edges in causal network, number of directed edges, total number of negatively correlated (red) edges, number of edges connecting early to late colonizers, number of edges connecting early with early or late colonizers, number of inconsistent directed edges (i.e., from late to early colonizers), and percentage of negatively correlated edges connecting early to late colonizers
