This system is based on six grades and four stages, reflecting the severity and extent of OA over the joint surface.
(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).
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).
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.
In the present study, binary and ternary blends based on two different grades of polystyrene (PS) and high impact polystyrene (HIPS) were prepared by melt mixing in a twin screw extruder, using a simplex-centroid mixture design.
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.
Professional organizations use a variety of systems, many of them, however, based on two prominent grading approaches: the system derived from the Canadian Task Force on the Periodic Health Examination [ 1, 21] and a successor of that system, the Oxford Centre for Evidence Based Medicine approach [ 22].
The RNFS scoring system assesses a symptom based on five ordinal grades that runs in a direction of GOOD → BAD.
The severity of DHF can be classified into four grades based on two pathophysiologic findings: hemorrhage and shock.
Total smear positive TB case detection increases from 110 cases to 200 when moving from a case definition based on two smears with a minimum grade of 1+ to a definition based on 1 smear with at least 1 AFB.
