Lessons from a methanol poisoning outbreak in Egypt: Six case reports

Table 2 Risk assessment for the rapid evaluation of outcome based on admission parameters, adapted from Paasma et al[29]

Risk group	Coma	Arterial pH	PaCO2	Death risk
A	No	≥ 7.00	-	5%
B	No	6.74-6.99	-	10%
C	No	< 6.74	-	25%
D	Yes	6.74-6.99	< 3.07	50%
E	Yes	6.74-6.99	≥ 3.07	83%
F	Yes	< 6.74	-	89%

Determination of the risk group of 1 patient on admission requires the combination of all conditions for the three parameters.
