More severe injuries were significantly associated with motor vehicle involvement, unlit roads at night, wider roads, perceptible road grades, and one-way streets.
For more than 50% of the cancer cells, faint or barely perceptible cytoplasmic staining was graded as being "very weak", weak cytoplasmic staining as "weak", cytoplasmic and membranous staining as "moderate", and strong cytoplasmic and membranous staining as "strong".
A grading system ranging from grade 1 (barely perceptible) to grade 4 (functionally significant) was used to indicate the severity of the scarring.
The skin response following application of the MN-containing plasters was graded as only barely perceptible (0.5) or mild erythema (1), regardless of the length of time the MN array remained within the skin.
Aristotle starts with the class of perceptible or physical magnitudes.
Facial motion was barely perceptible and complete eye closure was not possible, consistent with grade 5 facial palsies on the House-Brackmann facial nerve grading system.
Table 2 Subjective and objective grades for audio quality measurement Audio quality Subjective difference grade (SDG) Objective difference grade (ODG) Imperceptible 5 0 Perceptible, but not annoying 4 −1.0 Slightly annoying 3 −2.0 Annoying 2 −3.0 Very annoying 1 −4.0.
The induced erythema was graded 24±4 hours after irradiation, according to the COLIPA reference visual score: 0= no erythema, 1/2= perceptible redness reaction (MED), 1= moderate erythema, 2= severe erythema.
Table 1 ITU-T 5-point scale - ACR Grading value Estimated quality Perceived impairment 5 Excellent Imperceptible 4 Good Perceptible but not annoying 3 Fair Slightly annoying 2 Poor Annoying 1 Bad Very annoying.
For scoring, a five-grade impairment scale (1: very annoying, 2: annoying, 3: slightly annoying, 4: perceptible, but not annoying, 5: imperceptible) was used.
