Reporting of sample size calculations for randomized trials in dermatology: comparison of publications with registries.

Sample size calculations play an important role in the design and interpretation of clinical trials but have historically been poorly reported in publications (1,2). We systematically reviewed the rep...

Value of sample size for computation of the Bayesian information criterion (BIC) in multilevel modeling.

The Bayesian information criterion (BIC) can be useful for model selection within multilevel-modeling studies. However, the formula for the BIC requires a value for sample size, which is unclear in mu...

Bayesian sample size determination for longitudinal studies with continuous response based on different scientific questions of interest.

Longitudinal study designs are commonly applied in much scientific research, especially in the medical, social, and economic sciences. Longitudinal studies allow researchers to measure changes in each...

Sample size calculations for detecting disease-modifying osteoarthritis drug effects on the incidence of end-stage knee osteoarthritis in clinical trials: Data from the Osteoarthritis Initiative.

We previously published data representing calculations for sample sizes assuming that the reduction of the incidence of knee joint replacement (KJR) would be an endpoint to prove efficacy of a disease...

Sample size calculations need to be adequate and parsimonious.

Sample Size Definition in Cochrane Hepato-Biliary Trials

Sample size definition provides important information, allowing the groundwork for transparent reporting. The sample predefinition allows the trial to be large enough to be able to addres...

Validation of a Smart Phone App to Non-invasively Measure the Size of Children

Smart phones are omnipresent. Apps exist to calculate size of medical equipment and doses of medication if a valid weight or age is entered. During emergency situations, these values are o...

VNS During Rehabilitation for Improved Upper Limb Motor Function After Stroke

The primary study objectives are to assess the safety and feasibility of the therapy, including the surgical intervention and stimulation, as well as to provide information on the appropri...

Diagnosing Natriuretic Peptide Deficiency

In this pilot study, the investigators will determine the response of the natriuretic peptide (NP) hormone system after a dose of intravenous dexamethasone (a steroid medication). The goal...

Impact of Enhanced External Counterpulsation (EECP) on VO2 MAX

The purpose of this study is to assess the effects of 35 EECP sessions on cardiopulmonary training performance in healthy volunteers. Data from this study will be used to generate sample ...

Medical and Biotech [MESH] Definitions

The number of units (persons, animals, patients, specified circumstances, etc.) in a population to be studied. The sample size should be big enough to have a high likelihood of detecting a true difference between two groups. (From Wassertheil-Smoller, Biostatistics and Epidemiology, 1990, p95)

Studies in which the presence or absence of disease or other health-related variables are determined in each member of the study population or in a representative sample at one particular time. This contrasts with LONGITUDINAL STUDIES which are followed over a period of time.

Math calculations done for preparing appropriate doses of medicines, taking into account conversions of WEIGHTS AND MEASURES. Mistakes are one of the sources of MEDICATION ERRORS.

Studies in which a number of subjects are selected from all subjects in a defined population. Conclusions based on sample results may be attributed only to the population sampled.

Studies that are usually controlled to assess the effectiveness and dosage (if appropriate) of diagnostic, therapeutic, or prophylactic drugs, devices, or techniques. These studies are performed on several hundred volunteers, including a limited number of patients with the target disease or disorder, and last about two years. This concept includes phase II studies conducted in both the U.S. and in other countries.
