Psychiatric disorders as an outcome of neurological insult : a computation of relative risk
The purpose of this study was to examine the relative risk of psychiatric disorders occurring in patients diagnosed with neurological disorders. This study separately computed the relative risk ratios for identified psychiatric disorder (i.e., anxiety, mood disorders, somatization, schizophrenia, …

Maternal perinatal events as predictors of educational placement : computation of relative risk ratios
This study examined the relative risk of perinatal complications in common childhood disorders. Specifically, the ability of perinatal complications to predict membership into children's disorders was studied. The sample consisted of 634 normal children and children with mental retardation, …

Estimations of Relative Risk: Simulation Comparisons of Popular Methods In Sas and R
<p>Relative risk (RR)/Prevalence Ratio (PR) is an important measurement of the association between the outcome and the exposure factor. Compared with the odds ratio (OR), RR/PR is more intuitive and easier to explain to the general audience. But due to the constrained parameter space which may …

Coverage Properties of the Inverse Sinh Transformation and the Adjusted Wald Confidence Intervals for the Odds Ratio and the Relative Risk.
… confidence interval for the odds ratio and the relative risk in a 2 x 2 table. According to Robert Newcombe, the new interval should improve the coverage probabilities and shorten the width of the confidence interval for these ratios, but the new interval requires evaluation of coverage …

The Significance of Selected Medical and Environmental Factors in The Etiology of Falling Incidents Among The Hospitalized Elderly: A Relative Risk Assessment
The leading cause of traumatic disability and death by injury in the elderly population is falls. While the elderly most often fall at home, the falls which occur in the hospital are more amenable to scientific investigation. Within the hospital setting, detailed records of circumstances …

On the waterfront : a 25 year study of the relative risk & return of Florida single-family waterfront and inland homes (1977-2002)
This study applies the classic capital markets risk/return relationship-the riskier the investment, the greater the expected return-to the single-family home market. Treating coastal waterfront property as a unique asset class, its investment performance is measured and compared with that of inland …

Investigation of the role of dietary myo-inositol hexakisphosphate (phytate) on the relative risk of calcium oxalate kidney stone formation in black and white male South African subjects
… cOLlflterparts and that this contributes to the relative rarity of caOx kidney stone disease in this population group A modified indirect extraction/photometry method to measure urinary IPe was designed, developed and tested in the present study. This assay was then used to measure IPo in the …

Peri-slaughter ecology of Escherichia coli O157 and Salmonella enterica in feedlot beef cattle
Risk factors for prevalence of E. coli O157 prior to slaughter and the genotypic relationship between feedlot and slaughter isolates were investigated. The odds of E. coli O157 positive fecal samples from cattle fed brewers grains were 6 times that for cattle not fed brewers grains. The odds of E. …

Survival of adults with HIV-1 infection or Type 2 diabetes in the South African private sector
… levels of mortality and which subgroups have relative mortality that is within the insurance industry’s threshold for insurability. Relative mortality estimates are important in insurance since insurability is measured by relative mortality, not absolute mortality or other measures such as …

Spatio-temporal modelling of breast cancer incidence between 2000 and 2021 at sub-national levels in Iran: Bayesian disease mapping
… aims to assess levels and trends (2000-2021) of relative risk of breast cancer incidence and mortality at sub-national levels in Iran and their relation to key socioeconomic dimensions, to understand the full extent of geographical and social inequalities in the country associated with breast …

Mathematical models for vector-borne infectious disease mapping with application to Dengue disease in Malaysia
Few publications consider the estimation of relative risk for vector borne infectious diseases.Most of these articles involve exploratory analysis that includes the study of covariates andtheir effects on disease distribution and the study of geographic information systems tointegrate …

Early Detection of Treatment's Side Effects: A Sequential Approach
… we derive the asymptotic distribution of the relative ’savings’ in ASN as compared to fixed sample size. Moreover, we construct the post-test parameter estimate and studied its sampling properties, including its asymptotic behavior under local-type alternatives. These limiting behavior results …
