abstract objective: to investigate the anesthesia-postoperative awakening time (at) of hepatitis- related cirrhosis patients and their relations to grading scores, portal venous pressure (pvp), prealbumin (pa), and age, to predict postoperative at and provide a basis for adjustment of anesthetic doses during operation. methods: atotal of 71 patients with hepatic cirrhosis and hypersplenism at a...

Four methods have been proposed that can be used to test for associations between the states of discrete characters in cross-species data and that do not suffer from non-independence due to overcounting of data points. The tests are those of Ridley (1983), Burt (1989), Grafen (1989), and a new test called the ICDE test. The aim of the paper is to measure the Type I error rates for these methods...

in this paper data were collected from 120 farmers in north khorassan province for the two periods (2005-2007) in order to survey the role of rain-fed lentil risk profile for designing an insurance model. to evaluate looses of each risk, risk frequency, risk impact criteria’s as well as risk matrix were used. results showed that low risk was the largest risk area. during study period, a decreas...

Three non-randomized response (NRR) models (namely, the non-randomized triangular, crosswise and hidden sensitivity models) have recently been developed for analyzing dichotomous sensitive questions. Unlike existing randomized response (RR) models, no randomizing device is required for NRR models. This helps to reduce the cost, increase the efficiency, ensure the reproducibility, widen the appl...

BACKGROUND Confounding of mediator-outcome associations resulting in collider biases causes systematic error when estimating direct and indirect effects. However, until recently little attention has been given to the impact of misclassification bias. OBJECTIVE To quantify the impact of non-differential and independent misclassification of a dichotomous exposure and a dichotomous mediator on t...
