Parameters:
(1) age in years (from 20 to 90 years)
(2) predicted mortality (from 10 to 90%)
(3) Charlson comorbidity index (CCI, from 0 to 12)
(4) gender
(5) number of vasopressors days (from 0 to 5)
(6) number of ventilation days (from 0 to 5)
(7) number of hemofiltration days (from 0 to 5)

where:
• If vasopressors, ventilator or hemofiltration days exceed 5 days there are 2 options: either cancel the nomogram or set days to 5.
total score =
= SUM(points for all 7 parameters)
Interpretation:
• minimum score: 0
• maximum score: around 260
• The higher the score the worse the long-term survival.
