In this paper a new long-term survival distribution named long term weighted Lindley distribution is proposed. This new model allows us to fit data where a part of the population is not susceptible to the event of interest. This model can be used in clinical studies where a portion of the population can be cured during a treatment. An account of mathematical properties of the new distribution i...

The objectives of this study were to extend survival analysis into adulthood for patients with myelomeningocele (MM) and to compare survival curves for patients born with varying defect severity before and after 1975. We have reviewed existing data for 904 patients with MM seen in a large multidisciplinary children's clinic over 43 years. Before 1975, a major contributor to decreased survival i...

We have conducted an empirical investigation into the long term survival rates of some small but representative samples of the 30,000 largest UK limited companies. These companies were either a control or known to have used, or been interested in the use of, spreadsheets, spreadsheet based monte carlo simulation software, other spreadsheet and decision analysis software and/or related managemen...

AIM Short-term survival after emergency surgery for perforated diverticulitis is poor. Less is known about long-term survival. The aims of this study were to evaluate long-term survival after discharge from hospital and to identify factors associated with prognosis. METHOD All patients who underwent emergency surgery for perforated diverticulitis in five hospitals in Rotterdam, the Netherland...

OBJECTIVE To evaluate the long-term survival and factors that influence survival among a cohort of elderly trauma patients compared with an uninjured cohort. DESIGN A retrospective cohort analysis. DATA SOURCES Health Care Finance Administration, Baltimore, Md, Medicare data. SUBJECTS A cohort of elderly patients (n = 9424) hospitalized for injury in 1987 was identified using Medicare hos...

BACKGROUND Some studies have shown an improvement in the prognosis of patients with essential malignant hypertension (MHT), but data about long-term outcome and prognostic factors of these patients are scarce. METHODS We performed a single-centre retrospective analysis of 197 patients with MHT, diagnosed in the period 1974-2007. RESULTS Incidence of MHT remained stable along the different p...
