Noteworthy, the highest logistic regression coefficients obtained in the CL group were for the questions on “reading”, “driving at night”, “working with PC” and “watching tv” ( Figure 1 B), all four questions being related to functionality (OSDI B) and being nearly significant for the classification as symptomatic, subject only to the score given to “reading” ( p = 0.05, t -test of conformity).
