It can be used when discussing various levels or categories, particularly in educational or evaluative contexts.
Example: "The teacher noticed a significant improvement among the different grades in the recent standardized tests."
Alternatives: "among the various levels" or "within the different categories".
Amount of volume expansion after initial echocardiogram did not differ among the different grades of diastolic dysfunction.
The overall difference in MCM2 mRNA expression among the different grades of the precancerous epithelia dysplasia and SCC of the tongue is highly statistically significant (p = 0.000; Kruskal-Wallis test) (Table 1; Figure 2C).
Additionally, there was no difference in the ratio of C228T/C250T mutations among the different grades (Table 1).
Tables 2 and 3 shows the percentages of high and low AGR2 expressors among the different grades.
The different grades were also important, to assess possible differences in grading interpretations among the surgeons.
We prospectively evaluated LV diastolic dysfunction among patients presenting to the ICU with severe sepsis or septic shock, with special emphasis on the different grades of diastolic dysfunction.
There will be three showings for the different grades.
Expression of UHRF1 also differed among four groups with the different grade by Kruskal Wallis test (P=0.0156): although the distribution of UHRF1 expression in each group had a relatively wide range, the median value of UHRF1 expression in each group increased in parallel with increased grade.
The differences in time to progression to carcinoma among the three different grades were statistically significant (P=0.02, Figure 4).
As vascular densities significantly advanced from diffuse low‐grade to high‐grade gliomas (WHO grades II‐IV), we analyzed the course of Ang‐2 expression among the different WHO grades [low‐grade diffuse glioma (N = 14), anaplastic astrocytoma (N = 12), glioblastoma (N = 11)] compared to healthy controls (N = 3).
There was no significant difference in MVD among the different glioma grades (F = 1.432, P = 0.243).
