Moderators of the Effects of Exercise and Manual Therapy for People With Knee and Hip Osteoarthritis: A Secondary Analysis of a Randomized Clinical Trial

open access: yesArthritis Care &Research, EarlyView.
Objective This study aimed to investigate potential moderators influencing the effects of manual therapy and exercise therapy on pain and functional outcomes in individuals with knee and/or hip osteoarthritis, using data from the MOA trial. This is a secondary analysis of data from the MOA trial that compares the clinical effectiveness of manual ...

Sampling bias resulting from animal personality

Trends in Ecology & Evolution, 2009
Sampling is something most ecologists do, whether to estimate population size, determine trait distributions or collect samples for laboratory studies. Ecologists are well aware that most sampling techniques possess inherent sampling inefficiency and bias, and techniques have therefore been developed to minimise bias [1].

Extracellular microelectrode sampling bias

Experimental Neurology, 1970
Abstract The antidromic response latencies of 640 pyramidal tract neurons, isolated in pericruciate cortex of the cat, were measured after stimulation of the medullary pyramids. The expected time distribution of antidromic response latencies was then calculated from published values for axon diameters in silver-stained preparations; compensation for ...

Sampling bias in transgender studies

The Lancet Infectious Diseases, 2013
Thus, urban and clinic samples might not represent the sex lives of transgender women in less urban areas, of higher economic positions, or those who are not primarily sexually attracted to men. Although high HIV prevalences can serve as an advocacy instrument in drawing attention to the health of transgender women, labelling a group that experiences ...

Nozzle Sampling Bias

American Industrial Hygiene Association Journal, 1975
A mathematical model is proposed to describe the sampling bias in anisokinetic sampling of aerosols. The nozzle sampling bias is described as a function of the particle's free stream inertial parameter, P, and the particle's free stream Reynolds number, Re0, and the suction ratio, w0, of the sampling nozzle.

Sampling Bias in Respirometry

Physiological Zoology, 1992
Comparisons of the metabolic rates of species, populations, and treatment groups of animals are common. However, the data used in these comparisons may not be truly equivalent. We report the effects of varying (1) total time from which minimum metabolism is selected and (2) time over which metabolic rate is calculated (calculation interval) on ...

Sampling Bias in LinkedIn

Proceedings of the 25th International Conference Companion on World Wide Web - WWW '16 Companion, 2016
This paper describes a case study of sampling bias in LinkedIn, a major professional social network. The study collected a sample of 1,989 STEM students who graduated from a major public university between 2002 and 2014. Overall, 40\% of the graduates had a LinkedIn profile in summer of 2015.

Size Bias in Line Transect Sampling

Biometrics, 1987
Line transect sampling is used to estimate the number of individuals in a study area. It is usually assumed that the detections of individuals constitute independent events, and that the probability of detecting an item is a function of its perpendicular distance from the transect.
