Any marked changes in the grades could make life more difficult for universities looking to recruit those receiving their A levels.
In contrast, active and collaborative learning were not associated with significant changes in the grades of students in the top quintile.
Changes in the grades of low-achieving students are likely to be more conspicuous, since there are more grades still available to them compared to high achievers, who have relatively little room for improvement academically.
However, this value may not cause changes in the grading unless the patients' scores were borderline to the adjacent grade.
There was no change in the grade of 18 (56.3 %) patients, though a clinical improvement was observed in all of them.
Thus, the interaction coefficient β3 is the average change in the grade associated with participating in the BFP and having EOP status.
The change in the grade of dysphagia in our study was not different from those reported by other investigators (Knyrim et al, 1993; May et al, 1995; Wengrower et al, 1998).
Most changes in the CTCAE grade of quantitative laboratory parameters were from grade 0 to grade 1 or 2. Fifteen patients had a change to CTCAE grade 4, with the highest incidence rate of changes to CTCAE grade 4 in creatinine and low calcium levels.
Rather, it results from both changes in how the grade distribution is used over time (the grading distribution is more censored in later years) and changes in course selection.
Statistical analysis was performed using SAS 8.02 (SAS Institute Inc .. Wilcoxon signed rank test was used to analyse the statistical significance of change in the grades of ZPS status from cycle 1 to cycle 3, and cycle 1 to cycle 6.
