Euclidean Norm in Composite Severity Score to Evaluate an Allergic Reaction from Conjunctival Provocations

Abstract

Volume 5 • Issue 3 • 1000159 J Health Med Inform ISSN: 2157-7420 JHMI, an open access journal divided by the square number of challenges n 2 (n=i, if s i ≥ 2): 2 1 2 = = ∑ n i i j s C n (1) At a maximum of three challenges, at 0 ≤ s i ≤ 4 and at s th =2, Equation 1 conforms to the following two requirements: • Each combination of the s i results in a unique C j . • The decreasing C j value indicates an improvement of allergic severity (hyposensitisation). The C j , calculated for all possible 0 ≤ s i ≤ 4 with s th =2 and 1 ≤ n ≤ 3, are presented in Table 2.
