Hirano 2013 modified EREFS

Hirano 2013 modified EREFS: caller-assigned edema (absent 0, present 1), rings (none 0, mild 1, moderate 2, severe 3), exudates (none 0, mild_lt_10pct 1, severe_gt_10pct 2), furrows (absent 0, present 1; original 0-2 collapsed), stricture (absent 0, present 1). magent sums only (max 8; not later 0-9). No activity bands, inflammatory/fibrostenotic subscores, crepe-paper, or narrow-calibre. magent does not perform endoscopy. Not a diagnosis.
