The first column outlines the CO₂ emissions reduction in group 2. The subsequent columns compare the outcomes of the appointments between group 1 and group 2 when looking at admissions, including those related to underlying gastroenterolical diagnosis, at 90 days,deaths within 90 days and the number of blood tests requested.
CO2, carbon dioxide.
