For statistical analyses, the PFI was categorized as poor (combination of categories fair and poor), satisfactory, or good (good and excellent) [ 17].
Our results broadly suggest that, with inputs held constant, receiving a lower outcome than a comparison other is judged as fairer (and more satisfactory) when positively (vs. negatively) tied to the other.
To achieve categorisation in our study, three diabetes specialists independently classified CGM profiles into groups of very good, good, satisfactory, fair, and poor metabolic control.
These limits were also applied to define the Q-Score categories as very good, good, satisfactory, fair and poor (Additional file 1: Figure S3).
The groups of evaluated CGM profiles were used to define the Q-Score limits between categories of very good, good, satisfactory, fair, and poor glycaemic control.
This understanding was helpful to the medical school when, in 2006, they decided to change from 10-point scale to a criterion-referenced rating scale with only three descriptors (satisfactory, fair and unsatisfactory).
Excellent and good results were defined as satisfactory, whereas fair and poor results were defined as unsatisfactory.
The Q-Score was then calculated for all profiles, and limits were defined based on the categorised groups (<4.0, very good; 4.0 5.9, good; 6.0 8.4, satisfactory; 8.5 11.9, fair; and ≥12.0, poor).
We believe that a price of about $60 per barrel is fair, is satisfactory to consumers and to us as producers.
Reports on the first 17 units were published in September 2009; the EPA rated the structural integrity of 7 of these impoundments as "satisfactory," 9 as "fair," and 1 as "poor".
