Br J Sports Med 2011;45:478–491. doi:10.1136/bjsm.2010.080937 478 Accepted 2 March 2011 ABSTRACT Background Valid, reliable and responsive Patient-Reported Outcome (PRO) questionnaires for young to middle-aged, physically active individuals with hip and groin pain are lacking. Objective To develop and validate a new PRO in accordance with the COnsensus-based Standards for the selection of healt...

The probability of moose damage was studied in sapling stands and young thinning stands in southern Finland. Data from the eighth National Forest Inventory in 1986–92 were used for modelling. The frequency of damage was highest at the height of two to fi ve meters and at the age of ten to twenty years (at the time of measurement). Moose preferred aspen stands the most and least preferred Norway...

In this paper we characterize the identified set and construct asymptotically valid and non-conservative confidence sets for the quantile regression coeffi cient in a linear quantile regression model, where the dependent variable is subject to possibly dependent censoring. The underlying censoring mechanism is characterized by an Archimedean copula for the dependent variable and the censoring v...

Covariance analysis limits error, the degree of nuisance variation, and overparameterizing factors to accurately measure treatment effects. Data dealing with growth, carcass composition, and genetics often use covariates in data analysis. In contrast, nutritional studies typically do not. The objectives of this study were to 1) determine the effect of feeding diets containing dehulled, degermed...

This study aimed to determine the reliability and validity of items of the Japanese version of the CES-D (Center of Epidemiologic Studies Depression) scale when applied to independent community-dwelling Japanese elderly from the viewpoints of internal consistency and goodness-of-fi t for the model. Subjects were 1791 community-dwelling independent elderly people aged 60 and over. This study use...

comment on our study [1]. We regret that we did not provide the number of patients with normal lung (NL) and the equation for EVLW and lung weight. We are glad to provide these details now. Nine patients had NL and 21 had lungs heavier than NL (HL). We observed a close correlation between EVLW and postmortem lung weight in both groups (NL, r = 0.78, P < 0.05; HL, r = 0.83, P < 0.01). Th e linea...

An electrically conductive tubular element with a thin external electri-cally coating underthe action of an unsteady electromagnetic field the radio frequency range is considered. To analyze thermal re-gime, initial-boundary problem electrodynamics for two-layer non-ferromagnetic hollow cylinder under ex-ternal non-stationary formulated. The electromag-netic given by values axial component magn...

In 1930 Sergey L. Sobolev [6, 7] has proposed a construction of the solution of the Cauchy problem for the hyperbolic equation of the second order with variable coeffi cients in 3-d. Although Sobolev did not construct the fundamental solution, his construction was modified in 1986 by Romanov [4] to obtain that solution. However, these works impose a restrictive assumption of the regularity of g...

This paper examines the impact of time averaging and interval sampling data assuming that the data generating process for a given series follows a random walk with uncorrelated increments. We provide expressions for the corresponding variances, and covariances, for both the levels and differences of the aggregated series, demonstrating how the degree of temporal aggregation impacts these partic...

Background: Advances in BIA offer practical alternative approaches to assessing body composition in young adolescents and have not been studied for comparability. Methods: This study compared reliability and convergent validity of three fi eld tests (2-site skinfold, Omron and Tanita BIA devices) on young adolescents. Reliability was determined using intraclass correlation coeffi cients, conver...
