the 5-year survival rate is a good prognostic indicator for patients with gastric cancer that is usually estimated based on kaplan-meier. in situations where censored observations are too many, this method produces biased estimations. this study aimed to compare estimations of kaplan-meier and weighted kaplan-meier as an alternative method to deal with the problem of heavy-censoring. data from ...

The Kaplan–Meier estimator is a nonparametric estimator which may be used to estimate the survival distribution function from censored data. The estimator may be obtained as the limiting case of the classical actuarial (life table) estimator, and it seems to have been first proposed by Böhmer [2]. It was, however, lost sight of by later researchers and not investigated further until the importa...

Meier-Gorlin syndrome (MGS) is a rare autosomal recessive primordial dwarfism disorder, characterized by microtia, patellar applasia/hypoplasia, and a proportionate short stature. Associated clinical features encompass feeding problems, congenital pulmonary emphysema, mammary hypoplasia in females and urogenital anomalies, such as cryptorchidism and hypoplastic labia minora and majora.
