Arthritis Care &Research, EarlyView.Objective We investigated whether a diagnosis of rheumatoid arthritis (RA) affects the quality of inpatient acute myocardial infarction (AMI) care and long‐term mortality post‐AMI. Methods We analyzed data from 784,091 adults, 6,047 with a diagnosis of RA, from England and Wales hospitalized with AMI between 2005 and 2019 from the Myocardial Ischaemia ...

Testing for Spherical Symmetry of a Multivariate Distribution
, 1998 We consider a test for spherical symmetry of a distribution in Rdwith an unknown center. It is a multivariate version of the tests suggested by Schuster and Barker and by Arcones and Gine.

Addressing Economic Insecurities Can Improve Patient‐Reported Outcomes in Lupus
Arthritis Care &Research, EarlyView.Objective Economic insecurities, such as food, housing, transportation, and financial challenges, are modifiable risk factors and influence patient‐reported outcomes (PROs) in systemic lupus erythematosus (SLE). We examined the following: (1) associations between economic insecurities and PROs, and (2) the impact of screening and addressing economic ...

Tail behaviour of Gaussian processes with applications to the Brownian pillow [PDF]
In this paper we investigate the tail behaviour of a random variable S which maybe viewed as a functional T of a zero mean Gaussian process X, taking specialinterest in the situation where X obeys the structure whichis typical for limiting processes ...

Asymptotic distribution of rank statistics used for multivariate testing symmetry
Journal of Multivariate Analysis, 1971 Abstract The present paper contains assertions on asymptotic distributions of statistics used for the nonparametric multivariate testing symmetry. The results are proved under the hypothesis of symmetry H 1 , the near alternative and the general alternative.

Trajectories of Physical Function in Canadian Children with Juvenile Idiopathic Arthritis
Arthritis Care &Research, Accepted Article.Objectives We describe trajectories of physical function in children newly diagnosed with juvenile idiopathic arthritis (JIA) and identify trajectories with persisting functional impairments and associated baseline characteristics. Methods We included patients enrolled in the Canadian Alliance of Pediatric Rheumatology Investigators (CAPRI) Registry ...
