Tests for association were performed using both categorical case-control and Cox proportional hazards models [31].
This marker also impacted dimensional severity scores of schizophrenia, lending further support to the categorical case-control finding.
The small sample size, however, was somewhat mitigated by the four to eightfold increase in statistical power of a quantitative trait design over a categorical case-control analysis [4], [68].
In addition, we performed a categorical case-control allelic test of association within PLINK.
The results of chi-squared tests indicate that dentists' response to the 3-group categorical case scenario differed significantly for general and pediatric dentists.
The findings underscore the notion that paradigms for categorical case assignment are superimposed on a continuous distribution, which can result in substantial variation in prevalence estimation, especially when the measurements used in case assignment are not standardized for a given population (i.e. by gender, informant, culture, etc).
Kaplan Meier methods were used to calculate 1-, 5- and 10-year survival rates by categorical variables, cases diagnosed in the later years of the study period, 5- and 10-year survival was treated as censored.
Accordingly, while that assessment is ongoing, I am imposing a temporary pause on the entry of nationals from Iran, Libya, Somalia, Sudan, Syria, and Yemen, subject to categorical exceptions and case-by-case waivers, as described in section 3 of this order.
For genetic variations discovered to be associated with progression to AIDS-1987, sequelae including Kaposi's sarcoma (KS) and Pneumocystis carinii pneumonia (PCP) were tested in dichotomous case-case categorical and survival models.
RS-SNP is designed for genome-wide SNP data with binary categorical phenotypes, for example cases and healthy controls.
