OBJECTIVES We studied the outcomes of pediatric patients diagnosed with dilated cardiomyopathy (DCM) and their relation to epidemiologic and echocardiographic variables at the time of presentation. BACKGROUND The outcome of pediatric DCM patients ranges from recovery to a 50% to 60% chance of death within five years of diagnosis. The impact of heart transplantation and other emerging therapie...
The hazard function provides the instantaneous probability of death (or other key end point) at various times after diagnosis. Unlike the survival curve, the hazard function illustrates graphically or through calculations when deaths are common or uncommon. In this study, hazard functions were derived for prostate cancer by using survival data on large numbers of patients with prostate cancer w...

OBJECTIVE Diabetes is a common cause of shortened life expectancy. We aimed to assess the association between diabetes and cause-specific death. RESEARCH DESIGN AND METHODS We used the pooled analysis of individual data from 12 Spanish population cohorts with 10-year follow-up. Participants had no previous history of cardiovascular diseases and were 35-79 years old. Diabetes status was self-r...
In the frame of the Cox proportional hazard (PH) model, a novel two-step procedure for estimating age-period-cohort (APC) effects on the hazard function of death from cancer was developed. In the first step, the procedure estimates the influence of joint APC effects on the hazard function, using Cox PH regression procedures from a standard software package. In the second step, the coefficients ...
background & aim: we aimed to describe a standard survival analysis, so that we can analyze some factors related to the time of occurrence of different types of reflux (unilateral-left, unilateralright, and bilateral) in children with antenatal hydronephrosis (anh) and to provide an approach taking competing risks into account. methods & materials: we used data of 193 children that was collecte...
background: hypertension is one of the most important determinants of death due to vascular damage and is fast emerging as a high burden disease in india. however, its documentation is poor in the country. this study aims to estimate the rate and the causal pattern of mortality in a cohort of people with high blood pressure as compared to normotensives. methods: the study setting is varkkala, a...
AIMS To investigate whether strong cardiac sympathetic activity contributes primarily to sudden death or to worsening heart failure, and to determine the relationship of the size of cardiac noradrenaline stores to the mode of death. METHODS AND RESULTS The study population comprised 116 patients with congestive heart failure (ejection fraction 19+/-7%) and a mean follow-up of 18+/-19 months. ...
