20 There seems to be confusion about the extent of variation in issuing sickness certification, and there is little research evidence that identifies the size and nature of any variation.
The QTL analyses conducted in this study revealed several important findings relating to the genetic basis of variation in three issues of relevance to hop breeding programs: expedited plant sex identification, increased yield capacity and improved secondary metabolite profiles, with important implications for the future use of molecular selection methods in hop.
The most predictive parameter of 20%% variation in RBF issued from the Doppler was the variation in diastolic velocity, but the AUC was poor (0.75) [40.75
Related to this issue, variation in the outcome rates (i.e., percentages of participants who entered NHs; see Tables 2 and 3) may have led to the observed statistical heterogeneity.
There was little variation in the number of correct issues selected between the subgroups (p=0.20).
This is a challenge, because high speed equipment is not necessarily sensitive to variations in size/quality issues, and requires development of unique sensors and control systems.
This study shows how well morbidity helped in explaining variation in the number of prescriptions issued and in determining which group of patients are most likely to receive prescriptions.
Another issue is the variation in the number of cycles between superior/inferior and nasal/temporal truncated quadrants.
The studies discussed above and summarised in Table 1 reflect a growing recognition among veterinarians that traditional, large quantitative studies of cattle databases can only partly explain the variation in health related issues.
At present, however, this study suggests that many patients' experiences of care may be falling short of this ideal as a result of variation in service provision and issues relating to the ownership of reconstructive care.
