Random-effects meta-analyses are very commonly used in medical statistics. Recent methodological developments include multivariate (multiple outcomes) and network (multiple treatments) meta-analysis. Here, we provide a new model and corresponding estimation procedure for multivariate network meta-analysis, so that multiple outcomes and treatments can be included in a single analysis. Our new mu...

The spectrum of possible parameters of symmetric configurations is investigated. We propose some new constructions, mainly based on Finite Geometry and on extension methods. New parameters are provided, both for general symmetric configurations and for cyclic symmetric configurations. For several values of k, new upper bounds on the minimum integer E such that for each v≥ E there exists a (cycl...

We discuss the issue of conditioning on events with probability zero within an imprecise-probabilistic setting, where it may happen that the conditioning event has lower probability zero, but positive upper probability. In this situation, two different conditioning rules are commonly used: regular extension and natural extension. We explain the difference between them and discuss various techni...

this study examines iranian agricultural researchers’ attitudes regarding collaboration with extension workers and the variables associated with the researchers’ attitudes. data were obtained using a questionnaire developed by agricultural research centers of charmahal and bakhtiari, isfahan, safiabad and khuzestan in 1998. the findings re-vealed that the researchers’ attitudes towards collabor...

BACKGROUND The purpose of this study was to evaluate the potential relationship between Hashimoto's thyroiditis and BRAF(V600E) mutation status in patients with papillary thyroid carcinoma (PTC). METHODS A total of 619 patients with PTC who underwent total thyroidectomy with lymph node dissection were enrolled in this study. Univariable and multivariate analyses were used. RESULTS Hashimoto...

The Americanjoumal a/Occupational Therapy T he proXimal interphalangeal (PIP) joint is particularly susceptible to acute ligamentous injury, and such an injury can result in swelling without ligament laXity, collateral ligament laXity and disruption, or a partial or complete avulsion of the volar plate with or without bony involvement. Many articles have been written about methods for treatment...

The study determined the willingness and capacity of poultry farmers to pay for extension services in Nasarawa State, Nigeria. At this research used a sample size of 120 poultry farmers. Simple descriptive statistics, Kuppuswamy scale and Logit regression model were used data analysis. The results showed that majority of the poultry farmers (87.5%) indicated their willingness to pay for extensi...

More than 20% of U.S. paramedics are exposed to blood each year. Little is known about the circumstances that lead to these exposures. The objective of this study was to describe blood exposure events among U.S. paramedics. A mail survey was conducted in 2002-2003 among a nationally representative sample of licensed paramedics. Eighty percent of needle/lancet sticks involved non-safety devices....
