Wang et al reported a nomogram for predicting in-hospital mortality for a cancer patient with a nosocomial fungal infection. The authors are from Xi'an Jiaotong University and Baoji Traditional Chinese Medicine Hospital in China.
Patient selection: cancer patient with nosocomial fungal infection
Parameters:
(1) serum albumin in g/L
(2) platelet count in 10^9/L
(3) mechanical ventilation
(4) pulmonary metastases
(5) ECOG performance status

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 104.4
• maximum score: 309.52
value of X =
= (0.0267 * (score)) - 4.966
risk of in-hospital mortality =
= 1 / (1+ EXP((-1) * X))
Performance:
• The are under the ROC curve is 0.76.
