Because the studies used different physical activity measures in their tests for trend (e.g., energy expended, intensity, frequency, or duration), as well as different categorisation schemes, we did not conduct a formal meta-analysis of trend across studies.
Levitan brought to these trends a formal clarity, both broadening the scope of his mentors' artistic program and unifying its disparate elements in his markedly individual and romantic style.
However, since the sample size is limited with many essential results based on statistical trends, a formal randomised controlled trial is now required to determine if the pre- and postoperative gains in strength and objective functional capacity observed in this clinical trial are reproducible in a larger population.
For further analysis of trends, a formal time series analysis would be ideal, but this has some pitfalls, as described by Zheng et al. [ 18], and requires rich data, i.e. daily counts, which was beyond the scope of this study.
A formal test for a linear trend in the slope of the SRRs evaluated the hypothesis that β1 = 0 against the alternative hypothesis that duration or cumulative exposure predicts mortality.
Further studies are also needed to determine whether the less formalized curriculum in clerkship might explain concerns that professionalism and empathy diminish as training proceeds and whether a formal curriculum could prevent this trend.
