BACKGROUND In developing countries about 3.5% of children aged 0-5 years are victims of severe acute malnutrition (SAM). Once the morbidity has developed the cure process takes variable period depending on various factors. Knowledge of time-to-cure from SAM will enable health care providers to plan resources and monitor the progress of cases with SAM. The current analysis presents modeling time...

We propose a semiparametric method for the analysis of masked-cause failure data that are also subject to a cure. We present estimators for the failure time distribution, the cure rate, and the covariate effect on each of these, assuming a proportional hazards cure model for the time to event of interest and we use the expectation-maximization algorithm to conduct the likelihood maximization. T...

OBJECTIVE To determine whether detection of invasive cervical cancer by screening results in better prognosis or merely increases the lead time until death. DESIGN Nationwide population based cohort study. SETTING Sweden. PARTICIPANTS All 1230 women with cervical cancer diagnosed during 1999-2001 in Sweden prospectively followed up for an average of 8.5 years. MAIN OUTCOME MEASURES Cure...

elastomer compound based on nr/br was prepared using different kinds of nano-zno and zno. the effect of zinc oxide as an activator of sulfur cure on the mechanical and morphological properties of the compound was studied. the result of the mechanical properties showed that the tensile strength, elongation-at-break, resilience, and abrasion resistance of the compound prepared by zno (4 phr) are ...
