The approach usually involves constructing a time series of population-level rates for a particular quality improvement focus (eg, rates of attention-deficit/hyperactivity disorder [ADHD] medication initiation) and testing statistically for a change in the outcome rate in the time periods before and time periods after implementation of a policy/program designed to change the outcome.
Issues regarding adjustments for multiple testing, statistically significant thresholds, and biologically relevant alteration levels, have not been established for high-throughput DNA methylation studies.
We built a multivariable regression model by sequentially adding and testing statistically significant candidates from the univariable analysis, in order of effect size.
Compared with most other studies, the present one differs by testing statistically whether agreement is better than chance, rather than simply reporting the percent agreement, and by conducting formal statistical tests of whether patients under- or over-report.
Thus, the linear regression model that we use in this paper was a parsimonious and convenient approximation of the reality and it is useful for testing statistically our hypothesis that social patterning of BMI had changed over time.
This test involves recoding 8-day composite observations, during a 3-year assessment period, into those exceeding the criteria and those not exceeding the criteria, then testing statistically if the number exceeding the criteria is more than would be expected, with a specified Type I error rate (α = 0.1).
