Nomogram of Jiang et al for Predicting Control of Chronic Rhinosinusitis

Description

Jiang et al reported a nomogram for predicting control of chronic rhinosinusitis 1 year after FESS surgery (functional endoscopic sinus surgery). The authors are from Sun Yat-sen University and Guangzhou University in China.

Parameters:

(1) allergic rhinitis

(2) peripheral blood eosinophil count, probably absolute count in 10^9/L

(3) asthma

(4) tissue eosinophil ratio as a percent

Parameter	Finding	Points
allergic rhinitis	no	0
	yes	38.4
peripheral blood eosinophil count	< 0.3 * 10^9/L	0
	>= 0.3 * 10^9/L	67.8
asthma	no	0
	0	96
tissue eosinophil ratio	< 10%	0
	>= 10%	100

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 302.2

value of X =

= (-0.00001135 * ((score)^2)) + (0.01301 * (score)) - 2.223

probability of uncontrolled disease after FESS =

= 1 / ( 1 + EXP((-10 * X))

Performance:

• The area under the ROC curve is 0.76.
