For example, stratifying by whether exposures occurred before or after 20 years of age, suggested that for synthetic logs, the increased risk is limited to the exposures occurring after age 20 years (OR = 1.65, 95% CI 1.02, 2.67), rather than exposure occurring prior to age 20 years (OR = 1.09, 95% CI 0.46, 2.59), which was imprecise due to large confidence intervals.
Given this set of baseline parameters, patients could, for example, be stratified to several cohorts: (A) respiratory motion-gated PET/CT and radiotherapy, (B) respiratory motion-tracked PET/CT and radiotherapy, or (C) motion-suppressed PET/CT and radiotherapy.
For example, after stratified by the previous winter mortality, harvesting in nonaccidental deaths and CVD deaths was only found in the strata of "L" summers.
After adjustment for maternal characteristics and obstetric factors, the higher risk of stillbirth among women from the Middle East and North Africa was partly attenuated for example when stratified for mother's occupation.
For example, when stratified into quintiles, those with the highest level of the GBS (Q5) weighed approximately 2.56 kg more than those with the lowest level of the GBS (Q1) (β = 0.87 kg per SD increase in score, P < 0.0001).
Genetic risk prediction has several potential applications in medical research and clinical practice and could be used, for example, to stratify a heterogeneous population of patients by their predicted genetic risk.
This assumption allowed us for example to stratify patients into risk groups described by risk-specific toxicity parameters [ 58].
Indeed, biomarkers of disease are often an aid in clinical trials, For example, to stratify patients so that only those likely to respond to a particular therapy receive it.
For example, after stratifying study hospitals into low, medium, and high volume groups, the adjusted odds of the composite outcome decreased as specialisation increased among hospitals with a similar volume of orthopaedic procedures (table 5).
For example, when stratifying the marginal effects by levels of income and gender, girls coming from the top quintile of household income had their average odds of alcohol psychosocial problems 1.7 [odds ratio (OR) 1.68, 95% confidence interval (CI): 1.33 2.13] times higher than boys with comparable familial income.
