For the purposes of our study and in-keeping with our overall aim to identify a more evidence based referral process from the primary care setting, we used the variables recorded at the time of presentation to the GP as a proxy for the findings on clinical examination.
The treatment protocol used and the variables recorded at the date of first diagnosis, with the exception of the variable breed, were evaluated in a univariate Cox proportional hazard model and used to generate hazard ratios (HRs).
A socioeconomic index was developed using household characteristics as the variables recorded: wall, roof, and floor materials, piped water, number of rooms.
Additionally, we calculated the Intubation Difficulty Scale using the relevant variables recorded in the registry to reflect the actual difficulties experienced during the intubation process.
We reviewed the variables recorded in the WDHR-CCTR and presented categorical variables using frequencies and proportions, and continuous variables using medians and interquartile ranges.
All of the 60 participants were linked to the SEER records using the variables listed above.
3 10 We decided to build on this work and derive a set of risk prediction algorithms to quantify absolute risk of future cancer over a 10-year period using predictor variables recorded in the patient's primary care electronic record.
In the review protocol the decision was made to write to study authors for relevant associations or data that were not given in the study but could be calculated using the recorded variables.
We aimed to derive and externally validate risk prediction equations to quantify absolute 10 year risks of blindness and amputation in patients with diabetes by using variables recorded in their primary care electronic record.
Using a few physical chemical variables recorded continuously, the expert system is able to obtain water quality phenomena indicators, which can be associated, with a high probability of cause effect relationship, with human pressure on the water environment, such as urban discharges or diffuse agricultural pollution.
