DOI: 10.1002/cnm.3271
Abstract: Computational fluid dynamics models are increasingly proposed for assisting the diagnosis and management of vascular diseases. Ideally, patient-specific flow mea- surements are used to impose flow boundary conditions. When patient-specific flow measurements are unavailable, mean… read more here.

DOI: 10.1093/aje/kwad104
Abstract: The case-crossover study has been proposed as a suitable design when a brief exposure causes a transient change in risk of an acute-onset disease. In pharmacoepidemiology, the condition of "brief exposure" is rarely satisfied because… read more here.

DOI: 10.1111/add.14602
Abstract: BACKGROUND AND AIMS Vaporized nicotine products (VNPs) can vary in important characteristics including size, shape, flavor and nicotine yield. We examined whether complex interactions among these characteristics could affect smokers' VNP perceptions and usage patterns.… read more here.

DOI: 10.1371/journal.pone.0276154
Abstract: Several studies comparing resistance training (RT) frequencies may have been affected by the large between-subject variability. This study aimed to compare the changes in lower limbs maximal dynamic strength (1RM) and quadriceps femoris cross-sectional area… read more here.

DOI: 10.1371/journal.pone.0283382
Abstract: The aim of a clinical trial is to compare placebo to one or more treatments. The within-subject design is known to be more efficient than the between-subject design. However, in some trials that implement a… read more here.

DOI: 10.1373/clinchem.2018.290841
Abstract: BACKGROUND Within-subject biological variation data (CVI) are used to establish quality requirements for assays and allow calculation of the reference change value (RCV) for quantitative clinical laboratory tests. The CVI is generally determined using a… read more here.
