Determinants of Difficult‐to‐Manage and Treatment‐Refractory Axial Spondyloarthritis: A Cross‐Sectional Analysis Within a Longitudinal Cohort

open access: yesArthritis &Rheumatology, EarlyView.
Objective The purpose of this study was to estimate the prevalence of difficult‐to‐manage (D2M) and treatment‐refractory (TR) axial spondyloarthritis (axSpA) and to identify factors associated with D2M and TR disease in a longitudinal cohort. Methods We performed a cross‐sectional analysis on data from the Schroeder Arthritis Institute Spondylitis ...

Search and sweep numbers of finite directed acyclic graphs [PDF]

open access: yes, 1993
The search number of a graph is the least number of searchers needed to find any (possibly infinitely fast) intruder hiding in the vertices or edges of the graph.

Impact of cumulative glucocorticoid exposure on vancomycin clearance in hospitalized children: A retrospective cohort study

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Prior glucocorticoid exposure is associated with modestly increased vancomycin clearance in hospitalized children, partly mediated by renal function and inflammation and may contribute to subtherapeutic early drug exposure. Abstract Introduction Augmented renal clearance (ARC) can lead to subtherapeutic vancomycin exposure in children.

Partial identification with categorical data and nonignorable missing outcomes

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Nonignorable missing outcomes are common in real‐world datasets and often require strong parametric assumptions to achieve identification. These assumptions can be implausible or untestable, and so we may wish to forgo them in favour of partially identified models that narrow the set of a priori possible values to an identification region.

Acyclic partitioning of large directed acyclic graphs [PDF]

open access: yes, 2018
We investigate the problem of partitioning the vertices of a directed acyclic graph into a given number of parts. The objective function is to minimize the number or the total weight of the edges having end points in different parts, which is also ...

Minimal sufficient causation and directed acyclic graphs

open access: yes, 2019
Notions of minimal sufficient causation are incorporated within the directed acyclic graph causal framework. Doing so allows for the graphical representation of sufficient causes and minimal sufficient causes on causal directed acyclic graphs while ...
