Poisson Sequential Sampling Modified Towards Maximal Safety in Adverse Event Monitoring
Autor: Klaus Abt
Publikováno v: Biometrical Journal. 40:21-41
For applying Poisson sequential sampling in safety monitoring concerning new medical conditions (as well as in general control of safety) the one-sample Poisson sequential probability ratio test (SPRT) is modified. The modification results in an adap

Recognizing Ullrich-Turner syndrome by discriminant analysis of craniofacial structure
Autor: Klaus Abt, Christiane Kaiser
Publikováno v: American Journal of Medical Genetics. 62:113-119
In the present paper, we propose an efficient strategy for identification of craniofacial anomalies in the Ullrich-Turner syndrome (UTS). Standardized portrait- and profile-photographs were taken of 21 UTS patients with X-monosomy and 21 normal femal

ASSESSMENT OF SMALL HEALTH RISKS BASED ON EXACT SAMPLE SIZES
Autor: Klaus Abt, Albert Gülich
Publikováno v: Statistics in Medicine. 15:183-195
Exact sample sizes and critical numbers of cases for the rejection of a known event probability (10(-2) to 10(-6)) in favour of an increased probability (1.5- to 50-fold) at levels -alpha;beta- = -0.05; 0.10- and -alpha;beta- = -0.10;0.05- are presen

Planning controlled clinical trials on the basis of descriptive data analysis
Autor: Klaus Abt
Publikováno v: Statistics in Medicine. 10:777-795
In controlled clinical trials the problem of multiplicity of desired inferential statements finds attention at an increasing rate. In this paper the previously proposed concept of Descriptive Data Analysis (DDA), situated between Confirmatory and Exp

The Multicenter Isradipine Diuretic Atherosclerosis Study (MIDAS)
Autor: Klaus Abt
Publikováno v: JAMA: The Journal of the American Medical Association. 277:297
To the Editor. —The article by Dr Borhani et al 1 contains judgments of adverse event frequencies that call for some comments regarding the multiplicity 2,3 aspects of testing events (listed in their Table 4). Although the authors mention possible

Designing the Sample Size for Non-parametric, Multivariate Tolerance Regions
Autor: Klaus Abt, H. Ackerwn
Publikováno v: Biometrical Journal. 26:723-734
In supplementation of the work by ABT (1977, 1982) and ACKERMANN (1980, 1983) extensive ta.bles and approximite formulae are provided for the determination of the sample size for constructing “inner” and “outer” limits of non-parametric multi

Significance Testing of Many Variables
Autor: Klaus Abt
Publikováno v: Neuropsychobiology. 9:47-51
More than one variable of interest in pharmaco-EEG studies is the rule rather than the exception. The many-variables situation may arise from several types of EEG variables and/or from repeated measurements of these variables through time. In many ca

The influence of anxiety and pain sensitivity on experimental pain in man
Autor: Beat von Graffenried, Rolf H. Adler, René Spiegel, Erich Nüesch, Klaus Abt
Publikováno v: Pain. 4:253-263
A study was made of a number of factors that might be responsible for the unreliable results obtained in experimentally induced pain in man. In a randomised, double-blind, cross-over study on 32 healthy, male volunteers, the ischaemic pain test [14]

On the identification of the significant independent variables in linear models
Autor: Klaus Abt
Publikováno v: Metrika. 12:1-15
Methods for the identification of the significant independent variables in multiple linear regression and in the multiple regression approach to non-orthogonal analysis of variance and covariance are discussed. “Forward Ranking” and “Backward R
