However, we recognized that a shorter baseline period for observing Medicare claims-based diagnoses might impede total comorbidity ascertainment.
By 2011, the most recent year with complete ascertainment, a total of 521.4 cases pmp existed, of which 113.4 cases pmp had initiated treatment that year.
The strengths of this study include the population-based sample, the prospective design, the large number of participants, and ascertainment of total and cardiovascular death through the Cause of Death Registry at Statistics Norway.
The DISS had better ascertainment earlier; the total number of reported cases has decreased from 367 in 1983, 357 in 1993, 329 in 2003 and 216 in 2009.
Comparatively few genomic sequences are publicly available (6 individuals total) from the KhoeSan, and ascertainment bias on many of the standard SNP arrays may strongly skew estimates of genetic diversity in these populations.
This does not allow for proper ascertainment of the total number of people exposed to the drug and the rate and nature of adverse events, making it difficult to estimate the magnitude of risk and to analyze the root causes of adverse drug reactions.
A capture recapture analysis in this cohort indicated that using multiple sources of information for diabetes ascertainment detected 99% of total clinically incident cases, when compared with diagnostic information in a comprehensive review of medical records [ 25].
Measurement of mean cell size (to assess hypertrophy) and total cell number (to assess hyperplasia) allows ascertainment of recruitment, growth/shrinkage, fluctuation, and death of adipocytes.
Vital status as of 1 January 2008 was verified for 1,043 participants (ascertainment rate 97.0%) providing 34,363 total person-years of follow-up.
A two-source capture recapture model was used to estimate the size of the total diabetic population for each period 11 and showed ascertainment to be 97.6% and 98%, respectively.
