We present mexhaz, an R package for fitting flexible hazard-based regression models with the possibility to add time-dependent effects of covariates and account a twolevel hierarchical structure in data through inclusion normally distributed random intercept (i.e., log-normally shared frailty). Moreover, mexhazbased can be fitted within excess hazard setting by allowing specification expected m...
We performed a multicentre retrospective cohort study including 606,649 acute inpatient episodes at 10 European hospitals in 2010 and 2011 to estimate the impact of antimicrobial resistance on hospital mortality, excess length of stay (LOS) and cost. Bloodstream infections (BSI) caused by third-generation cephalosporin-resistant Enterobacteriaceae (3GCRE), meticillin-susceptible (MSSA) and -res...
hyperandrogenism affects 2-6% of all women. hypertension is one of disturbances which is related to androgen excess. higher intakes of vitamin c and vitamin e have been associated with lower blood pressure. tho investigate the effect of these vitamin supplementation on blood pressure in hyperandrogenic women, a randomized, double-blind, placebo-controlled study was designed on 56 women 18-54 ye...
BACKGROUND Breast cancer survival is higher in less deprived women, even amongst women whose tumor was screen-detected, but reasons behind this have not been comprehensively investigated. METHODS The excess hazard of breast cancer death in 20,265 women diagnosed with breast cancer, followed up to 2012, was estimated for screen-detected and non-screen-detected women, comparing more deprived to...
Four approaches to estimating a regression model for relative survival using the method of maximum likelihood are described and compared. The underlying model is an additive hazards model where the total hazard is written as the sum of the known baseline hazard and the excess hazard associated with a diagnosis of cancer. The excess hazards are assumed to be constant within pre-specified bands o...
Many forest stands in this country as well as in numerous underdeveloped countries, are overstocked with small-diameter trees (Wolfe 2000, Wolfe and Moseley 2000). These trees pose both a health hazard and a fire hazard to the forests, and excess stems should be removed, but presently they have too little market value to justify their removal. Before these stems are utilized, value-added produc...
PURPOSE Modeling excess and relative mortality represents two ways of considering general population mortality rates (ie, background mortality) in cohort studies. Excess mortality is obtained by subtracting the expected mortality from the observed mortality (additive hazard model). Relative mortality is obtained by dividing the observed mortality by the expected mortality (multiplicative hazard...
Background: Ondo city in Ondo State Nigeria includes Ondo East and West could be described as a research city due to antecedent number of research institutes. Materials and Methods: Dose due to radioactivity content of soil samples from sixteen waste dump sites in Ondo, Southwestern Nigeria was determined using gamma-ray spectrometer in order to evaluate the radiation hazard health profile and ...
