Loss of power from an optimistic alternative hypothesis.

Statistics in medicine

Blumenson LE.
PMID: 3368672
Stat Med. 1988 Apr;7(4):457-66. doi: 10.1002/sim.4780070402.

In the planning of a clinical trial to compare the proportion of responses to two treatments one determines the sample size to yield the desired power of achieving a significant difference at a pre-selected type I error under the...

Assessing diagnostic reliability and estimating incidence rates associated with a strictly progressive disease: dental caries.

Statistics in medicine

Espeland MA, Murphy WC, Leverett DH.
PMID: 3358020
Stat Med. 1988 Mar;7(3):403-16. doi: 10.1002/sim.4780070306.

This paper presents a general approach for simultaneously assessing, from serial data, diagnostic consistency, interrater reliability and incidence of a strictly progressive disease. Observed data are viewed as incomplete: diagnostic errors are not distinguished from true diagnoses. We introduce...

The summarizing of clinical experiments by significance levels.

Statistics in medicine

Anscombe FJ.
PMID: 2218173
Stat Med. 1990 Jun;9(6):703-8. doi: 10.1002/sim.4780090617.

For a controlled clinical experiment in which two alternative treatments are compared, the statistical report often culminates in a significance test of the null hypothesis of no difference between the treatments, and significance at the 5 per cent level...

A bibliography and comments on the use of statistical models in epidemiology in the 1980s.

Statistics in medicine

Gail MH.
PMID: 1805315
Stat Med. 1991 Dec;10(12):1819-85. doi: 10.1002/sim.4780101204.

This paper reviews developments in statistical modelling in epidemiology in the 1980's, with emphasis on cohort and case-control studies. The central roles of the logistic and proportional hazard models are highlighted, and it is shown how these models lead...

Statistics in medical journals: developments in the 1980s.

Statistics in medicine

Altman DG.
PMID: 1805317
Stat Med. 1991 Dec;10(12):1897-913. doi: 10.1002/sim.4780101206.

This paper reviews changes in the use of statistics in medical journals during the 1980s. Aspects considered are research design, statistical analysis, the presentation of results, medical journal policy (including statistical refereeing), and the misuse of statistics. Despite some...

Evaluation of statistics teaching given to medical undergraduates.

Statistics in medicine

Newcombe RG.
PMID: 2244077
Stat Med. 1990 Sep;9(9):1045-55; discussion 1057-62. doi: 10.1002/sim.4780090909.

Medical undergraduates in all United Kingdom medical schools receive statistics teaching, but attempts to establish the efficacy of this teaching have been scanty. Establishment of clear educational objectives is a prerequisite to meaningful evaluation. Most medical schools have attempted...

Measuring interrater reliability among multiple raters: an example of methods for nominal data.

Statistics in medicine

Posner KL, Sampson PD, Caplan RA, Ward RJ, Cheney FW.
PMID: 2244082
Stat Med. 1990 Sep;9(9):1103-15. doi: 10.1002/sim.4780090917.

This paper reviews and critiques various approaches to the measurement of reliability among multiple raters in the case of nominal data. We consider measurement of the overall reliability of a group of raters (using kappa-like statistics) as well as...

How many raters? Toward the most reliable diagnostic consensus.

Statistics in medicine

Kraemer HC.
PMID: 1609173
Stat Med. 1992 Feb 15;11(3):317-31. doi: 10.1002/sim.4780110305.

When faced with a decision whether or not to treat a patient, to enter or to withdraw a patient from a clinical trial, or any other such binary decision, based on diagnosis with unsatisfactory reliability, can a consensus diagnosis...

Discriminant analysis based on multivariate response curves: a descriptive approach to dynamic allocation.

Statistics in medicine

Albert A.
PMID: 6648124
Stat Med. 1983 Jan-Mar;2(1):95-106. doi: 10.1002/sim.4780020111.

We examine the problem of discriminating between two groups in the context of multivariate response curves observed over a specified time interval. We propose a descriptive solution for the case where one can determine the response curves by linear...
