TL;DR: The robustness and power of various versions of parametric analysis of covariance applied to small samples of ordinal scaled data are investigated through computer simulation and the hierarchical approach which first tests for homogeneity of regression slopes and then fits separate slopes if there is significant non-homogeneity produced significance levels that exceeded the nominal levels.

TL;DR: Higher fibrinogen levels were associated with increased platelet aggregability, however, the association between fibr inogen and platelets aggregability was genotype specific, which may be responsible for the conflicting findings regarding PlA genotype and platelet aggregation.

TL;DR: DMP1 is a pivotal tumor suppressor for both human and murine lung cancers and was found in mutually exclusive fashion with LOH of INK4a/ARF or that of P53.

TL;DR: Suggested revisions to the American Dental Association's 1985 guidelines for acceptance of anti-gingivitis chemotherapeutic agents articulate certain aspects of study design which were implicit in the 1985 guidelines, clarify language on cross-over designs and independence of studies, and recommend use of a United States population in at least one trial supporting a product.
