INTRODUCTION Quantitative electrocardiographic (ECG) waveform analysis provides a noninvasive reflection of the metabolic milieu of the myocardium during resuscitation and is a potentially useful tool to optimize the defibrillation strategy. However, whether combining multiple ECG features can improve the capability of defibrillation outcome prediction in comparison to single feature analysis i...

We exhibit a general class of interactive decision situations in which all the agents benefit from more information. This class includes as a special case the classical comparison of statistical experiments à la Blackwell. More specifically, we consider pairs consisting of a game with incomplete information G and an information structure S such that the extended game CðG;SÞ has a unique Pareto ...

BACKGROUND Among patients with adhesive small bowel obstruction (ASBO) initially managed with a conservative strategy, predicting risk of operation is difficult. METHODS We investigated ASBO patients at 2 different periods to derive and validate a clinical prediction model for risk of operation. RESULTS One hundred fifty-four patients were enrolled into the derivation cohort and 96 into the...

In the article by de Man-van Ginkel et al, “In-Hospital Risk Prediction for Post-stroke Depression: Development and Validation of the Post-stroke Depression Prediction Scale,” which published online on August 26, 2013, and appeared in the September 2013 issue of the journal (Stroke. 2013;44:2441–2445. DOI: 10.1161/STROKEAHA.111.000304), a correction is needed. On page 2444, in Table 6, the four...

As I read the study by Bakhtiari et al. (1), I noticed that they miscalculated the positive predictive value. They indicated that the positive predictive value of the PCR assay was 100%. But when I placed the values on the table and calculated the positive predictive value of the PCR assay, I found it 83.3%.

  Abstract   Background: Squamous cell carcinoma (SCC) constitutes the main oral malignancy .   Parallel to better understanding of molecular and genetic patterns of tumor behavior, more precise correlation of tumor markers such as Epidermal Growth Factor (EGF) and Laminin-5 are sought to estimate macroscopic and microscopic tumor status .   Methods: We conducted a cross-sectional study collect...

The predictive value of a combination of clinical and radiological features with interferon-γ release assay (IGRA) for diagnosis of active tuberculosis (TB) disease among TB-exposed children is unknown.150 symptomatic HIV-negative children (aged 3 months to 14 years), prospectively recruited through active contact tracing, were included. Backward stepwise logistic regression and bootstrapping t...

BACKGROUND Assessments of risk for pressure ulcers in critical care patients may not include important predictors. OBJECTIVE To construct risk-prediction models of hospital-acquired pressure ulcers in intensive care patients and compare the models' predictive validities with validity of the Braden Scale. METHODS Data were collected retrospectively on patients admitted to intensive care from...

BACKGROUND The optimal method for early prediction of human West Nile virus (WNV) infection risk remains controversial. We analyzed the predictive utility of risk factor data for human WNV over a six-year period in Connecticut. RESULTS AND DISCUSSION Using only environmental variables or animal sentinel data was less predictive than a model that considered all variables. In the final parsimon...
