OBJECTIVE: To examine genetic influences for quantitative refraction. Spherical equivalent and its related binary traits of myopia and hyperopia are highly correlated within families. Many linkage regions have been reported for myopia, high myopia, ...

Anterior ocular biometry using 3-dimensional optical coherence tomography.
29 Apr 2009 PURPOSE: To evaluate anterior ocular biometry by comparing the measurements of central corneal thickness (CCT) and anterior chamber depth (ACD) with 3-dimensional corneal and anterior segment optical coherence tomography (CAS-OCT) and other methods. ...

What is the value of a p value?
29 Apr 2009 Successful publication of a research study usually requires a small p value, typically p < 0.05. Many clinicians believe that a p value represents the probability that the null hypothesis is true, so that a small p value means the null hypothesis ...

Inaccuracy of intraocular lens power prediction for cataract surgery in angle-closure glaucoma.
28 Apr 2009 
PURPOSE: To assess the accuracy of intraocular lens (IOL) power predictions for cataract surgery in eyes with primary angle-closure glaucoma (ACG). Because of shifting of the capsular bag apparatus and shortening of the axial length, preoperative ...

28 Apr 2009 This paper presents Bayesian multivariate disease mapping and ecological regression models that take into account errors in covariates. Bayesian hierarchical formulations of multivariate disease models and covariate measurement models, with related ...

Propensity scores and M-structures.
28 Apr 2009 In a recent issue of Statistics in Medicine, Ian Shrier [Statist. Med. 2008; 27(14):2740-2741] posed a question regarding the use of propensity scores [Biometrika 1983; 70(1):41-55]. He considered an 'M-structure' illustrated by the directed acyclic ...

Risk-adjusted monitoring of survival times.
28 Apr 2009 We consider the monitoring of surgical outcomes, where each patient has a different risk of post-operative mortality due to risk factors that exist prior to the surgery. We propose a risk-adjusted (RA) survival time CUSUM chart (RAST CUSUM) for ...

Optimal choice of the number of treatments to be included in a clinical trial.
28 Apr 2009 It is common for a number of potentially effective treatments to be available for clinical evaluation. Limitations on resources mean that this inevitably leads to a decision as to how many, and which, treatments should be considered for inclusion in ...

Bayesian decision sequential analysis with survival endpoint in phase II clinical trials.
28 Apr 2009 Chen and Chaloner (Statist. Med. 2006; 25:2956-2966. DOI: 10.1002/sim.2429) present a Bayesian stopping rule for a single-arm clinical trial with a binary endpoint. In some cases, earlier stopping may be possible by basing the stopping rule on the ...
