Socioeconomic status was modeled as a categorical variable based on the three grade of employment groups.
Subjects' periorbital wrinkles were evaluated with a double-blind test by two dermatologists based on a wrinkle grade (Table 2), which was developed by the Korea Food and Drug Administration.
This system is based on six grades and four stages, reflecting the severity and extent of OA over the joint surface.
In the Aarhus method [ 7], fat lesion scores are based on four grades: normal (score 0); slight, <25% of the subchondral bone area of the DVU is affected (score 1); moderate, 25 to <50% is affected (score 2); and severe, ≥50% is affected (score 3).
We recently proposed the Cerebral Recovery Index (CRI), an index based on a combination of five qEEG measures grading the severity of hypoxic brain damage on a scale from zero to one to facilitate prognostication [2].
The range and costs of the services are again comparible but the phone support is based on two grades of telephone: a general enquiries line financed by a national call rate (0845) number; and a PC helpline charged at £1.50 a minute.
The RNFS scoring system assesses a symptom based on five ordinal grades that runs in a direction of GOOD → BAD.
(3) In view of the accuracy requirement for stiffness measurement, the track stiffness measurement can be categorized based on three grades, namely low accuracy (10 kN/mm, substructure disease identification, for heavy haul railways mainly), medium accuracy (1 kN/mm, potential safety hazard checking), and high accuracy (0.1 kN/mm, evaluation of track regularity, for high-speed railways mainly).
The tumors were analyzed based on three grading criteria: (1) the presence of hypointensity on SWI; (2) the ratio of the area of hypointensity in the tumor; and (3) the dominant structure of hypointensity in the tumor.
Cast films, based on two capacitor-grade isotactic polypropylene (iPP) homopolymers, were manufactured using three different extruders under different crystallization conditions and subsequently biaxially oriented using a laboratory stretching machine.
