In addition, following Evanno et al. [65], ΔK, where the modal value of the distribution is located at the real K, was also calculated using the software Structure2[1].2-sum (supplied by Dorothée Ehrich).
We estimated the total duration of each hormonal medication by summing the total days supplied for all prescriptions.
This method required wage rates for laboratory technicians and pathologists, productivity levels for technicians, expected abnormal sample rate and negative review, facilities requirements, and lump-sum supplies costs.
The MPR was calculated as the sum of days supplied, by class, over a 1-year period divided by 365.
Drug utilization was measured as the sum of days supplied with a refill in a particular drug class over a period of 1 year pre- and post-index.
Companies such as VECO could make huge sums by supplying equipment and services to big oil companies.
For patients who had a summed days supply > 358, the value of days covered was set as 358.
In sensitivity analyses, we examined cancer risk associated with duration of glargine use when duration was calculated by summing days supply for each prescription.
The risk ratio was 1.2 (95% CI 0.9 1.6) when we calculated duration based on time between prescriptions and 1.6 (1.0 2.4) when we calculated duration by summing days supply for each prescription.
The total days supplied will be calculated as the sum of days dispensed within the study period.
The aggregate operational skills then depend on the sum of general skills supplied by the employees, (q_{1}+q_{2}+dots +q_{n}), and on the general skills supplied by the entrepreneur, (q).
