Since Q3-5, Q12 Q12, and pain were significantly correlated with MCS, Q3 was the only question correlated with both MCS and TLKV (Table 5).
The main outcome measure was patient perception of the voice following total laryngectomy in response to specific questions correlated with sociodemographic/treatment factors.
Statistically speaking, we are interested here in how well the questions correlate with one another.
The answers to SRH questions correlate with life habits, disease, physical functional ability, symptoms, education, income, wealth, social capital, age, sex, parental health, attitudes etc [ 3- 9].
The same procedure was repeated for the SF-8 to identify questions with highest correlation to mental and physical quality of life scores, and for the PRIME MD to identify which question correlated best with screening positive for depression.
The factor loadings, which show the extent to which each question is correlated with each factor are shown in Table 2.
This allowed us to determine whether the behavior or attitude in question was correlated with exam performance and whether this relationship was mediated by classroom structure.
Initially, we used the gamma rank correlation to explore whether responses on any of the 14 survey questions were correlated with responses on the other questions.
Special interest was paid to the question whether component orientation correlates with early functional, subjective and radiological outcomes or even higher revision rates.
Indeed, both questions correlated significantly with the GÜF sum score, the here defined measure for hyperacusis.
