A comparison between cytological gradings obtained by two methods and the histological grade was done and sensitivity, specificity, diagnostic accuracy, and concordance and discordance rates were calculated.
Studying the effect of these parameters on flotation recovery and grade was done by analysis of variance, ANOVA.
The phase 1 stratification (by gender, region and grade) was done by proportional allocation and the number of classes needed was calculated for each gender, region and grade which resulted in an equal probability sample.
All laboratory tests were carried out under standardized conditions and their interpretation together with complete revision of the histopathological diagnoses, type and grade was done within the context of this study according to present-day guidelines.
Keep the objects only if they meet the grade, be done with them if they fail.
The ratings are based on Morningstar's measure of risk-adjusted performance, and grading is done on a curve.
As in school, our risk grading is done on a curve.
Because Gleason grading is done manually by a pathologist visually examining glass (or digital) slides subtle morphologic and architectural differences of histological attributes, in addition to other factors, may result in grading errors and hence cause high inter-observer variability.
Some non-profits ship donated clothes directly to foreign dealers, and the grading is done overseas.
Embryo grading is done in all IVF laboratories, but it remains a subjective process and IVF programs may vary in the types of grading system they use.
