Despite the rise in grade retention in poor areas in rural China recently, little work has been done to understand the impact of grade retention on the educational performance of students in these areas in rural China.
We did not find any negative social or psychological impact of grade-skipping.
A synthesis of many studies by a professor of gifted education, Karen B. Rogers, on the impact of grade-skipping showed uniformly positive effects across a range of academic outcomes.
Another study, by researchers Gregory J. Park, David Lubinski and Camilla P. Benbow, that followed highly gifted children 40 years into their adulthood and examined the long-term impact of grade-skipping related to science, technology, engineering and mathematics (STEM) came up with similar findings.
The impact of grade on overall and stage-specific survival was assessed using Cox regression analysis.
Previous studies found a statistically significant impact of grade of necrosis after neo-adjuvant treatment, surgical status, and histological subtype on OS and/or DFS [ 30- 33].
Second, as the base case did not allow the impact of presenteeism to vary in severity, the impact of grading it according to the number of dimensions reported was tested.
Given the magnitude of difference in median survival in these adjuvant trials and the potential impact of grade on survival, it is feasible that stratifying upon grade could alter the median survival difference and possibly the significance of these trial results.
