Table 2

Mean Ottawa scores parameters for morning procedures.

	Split-dose PEG	Single-dose PEG	value
Right colon	1.51	1.88	0.042
Mid colon	1.19	1.43	0.212
Left colon	0.99	1.39	0.031
Total fluid	0.61	0.80	0.090
Total Ottawa	4.31	5.51	0.035

Ottawa score by colon segment and total Ottawa score for the entire colon. Lower numbers are better. PEG: polyethylene glycol.
