Educational level was coded into four categories: degree-level or equivalent qualifications, A-level or equivalent, General Certificate of Secondary Education (GCSE) or equivalent and no qualifications, while the index of multiple deprivation was coded into quintiles.
Again, the EQ-5D Index leads to slightly higher scores with the 3L version, though the difference in scores between categories (degree-no degree, male female) was very similar on both Indices and VAS.
At the hospital level, while plotting all four categories for degree of severity/complications, we see again a similar pattern.
Because some LMAs are quite small, we settled on a version based on 10-year age groups and three qualification categories (grouping degree with post-school).
For instance a miniature car is a car and a toy, and for both categories the degree of membership (possibility) is 1.
Similar results were found for all three categories or degree of ruralness (or population density).
Four education categories including degree from elementary, middle, high school, and college and above, were self-reported by participants.
In addition we assessed effect modification by stratifying our analyses by sex, age (30 65 or > 65 years), socioeconomic status (five categories), and degree of urbanization (five categories).
These responses were grouped into five categories indicating degree of remoteness: major city, inner regional, outer regional, remote and very remote.
For each of the three haploSNP categories, the degree of achieved ploidy reduction depends on whether the critical form of the target site occurs in only one (reduction to diploid), two (reduction to tetraploid), or three (reduction to hexaploid) subgenomes.
