BACKGROUND AND PURPOSE NIH Stroke Scale certification is required for participation in modern stroke clinical trials and as part of good clinical care in stroke centers. The existing training and certification videotapes, however, are more than 10 years old and do not contain an adequate balance of patient findings. METHODS After producing a new NIHSS training and demonstration DVD, we select...

This paper studies correction for chance in coefficients that are linear functions of the observed proportion of agreement. The paper unifies and extends various results on correction for chance in the literature. A specific class of coefficients is used to illustrate the results derived in this paper. Coefficients in this class, e.g. the simple matching coefficient and the Dice/Sørenson coeffi...

An affective text may be judged to belong to multiple affect categories as it may evoke different affects with varying degree of intensity. For affect classification of text, it is often required to annotate text corpus with affect categories. This task is often performed by a number of human judges. This paper presents a new agreement measure inspired by Kappa coefficient to compute inter-anno...

OBJECTIVES The QuantiFERON-TB Gold in-tube test (QFT-GIT) and the tuberculin skin test (TST) are used to diagnose latent tuberculosis infection (LTBI). However, conclusive evidence regarding the agreement of these two tests among high risk contacts is lacking. This systematic review and meta-analysis aimed to estimate the agreement between the TST and the QFT-GIT using kappa statistics. METHO...

PURPOSE To assess the performance of a refined Web-based tool for documenting retinal hemorrhage characteristics in suspected abusive head trauma. METHODS Using a comprehensive tabular secure platform, with access to digital images in color, black and white, and 4-zone system schematic overlay, four pediatric ophthalmologists performed pilot testing with 80 images for tool refinement. In a se...

We demonstrate that a nonthermal distribution of particles described by a kappa distribution can be accurately approximated by a weighted sum of Maxwell–Boltzmann distributions. We apply this method to modeling collision processes in kappa-distribution plasmas, with a particular focus on atomic processes important for solar physics. The relevant collision process rate coefficients are generated...

AIM The aim of the study was to investigate whether impairments associated with cerebral palsy were stable between childhood and adolescence. METHOD The Study of Participation of Children with Cerebral Palsy Living in Europe (SPARCLE) longitudinal study was conducted in nine European regions. In total, 818 children aged 8 to 12 years were randomly selected from population-based registers; 594...

OBJECTIVE To test the reliability and validity of the DIGS in Spanish population. METHODS Inter-rater and test-retest reliability of the Spanish version of DIGS was tested in 95 inpatients and outpatients. The resultant diagnoses were compared with diagnoses obtained by the LEAD (Longitudinal Expert All Data) procedure as "gold standard". The kappa statistic was used to measure concordance be...

OBJECTIVE To measure agreement between nine structured approaches for diagnosing childhood tuberculosis; to quantify differences in the number of tuberculosis cases diagnosed with the different approaches, and to determine the distribution of cases in different categories of diagnostic certainty. METHODS We investigated 1445 children aged < 2 years during a vaccine trial (2001-2006) in a rura...

OBJECTIVE to analyse the Redness, Oedema, Ecchymosis, Discharge, Approximation (REEDA) scale reliability when evaluating perineal healing after a normal delivery with a right mediolateral episiotomy. METHOD observational study based on data from a clinical trial conducted with 54 randomly selected women, who had their perineal healing assessed at four time points, from 6 hours to 10 days afte...
