A detailed ocular history (cataract surgery, event to onset of symptoms, time to presentation, and previous treatment history in referred cases), the demography (age, gender), laterality, systemic factors (diabetes and immune status) were recorded.
Questions covered demography (age, gender), education level, physical activity, smoking, menopausal status, and use of hormone replacement therapy (HRT).
Parameters of the hepatobiliary system were evaluated preoperatively, including demography, age, gender, clinical symptoms, biliary complication, localization of cyst, and imaging findings (ultrasonography, computed tomography (CT) scan, magnetic resonance cholangiopancreatography (MRCP), and endoscopic retrograde cholangiopancreatography (ERCP)).
These data allowed us to assess the evolutionary history (demography, age and origins) of various Chinese populations and to address the hypothesis that the observed phylogeographic divisions are consistent with past range fragmentation by Pleistocene glaciations.
Before being assigned to a group, all subjects completed a baseline assessment that included demography (age, occupation, and education level), measures of alcohol and tobacco use, and behavior change items.
The contribution of different age groups to overall transmission will depend on local demography, age-dependent protection by malaria interventions (such as the use of bed nets or time spent in the house and therefore personally protected by indoor residual spraying), and human to mosquito contact patterns.
The questionnaire elicited information on demography (age, gender, years of practice experience, medicated glasses use, and average number of patient treated daily), perception of ocular health, reasons and timing of eye care visit, safety eye goggle and face mask use, barriers to regular use and ways to improve regular goggle use.
Both of these databases contain individual patient-level information including patient demography (age, gender, location, etc), attending physicians, diagnoses and procedures performed, service transfers while in hospital, specialty services received (e.g. physiotherapy, occupational therapy), and case complexity (e.g. resource intensity weight).
"Every significant development in the demography of aging on the world scene over the past three decades has been either organized by George Myers or he has been a participant in it," said George L. Maddox, director of the Center for the Study of Aging and Human Development at Duke, in Durham, N.C.
But the story is further complicated as a result of additional experiments on the demography of aging.
