Probability, proof, and clinical significance

چکیده
A study reports that treatment A “provided signifi cantly better pain relief” than treatment B. How do you know if the effect is real or due to chance? Assuming that the difference between treatment groups on the outcome is statistically signifi cant, does this mean that your patients will have a clinically signifi cant improvement? This article explores these questions as well as provides some additional points to consider when critically appraising and conducting research.

متن کاملProbability Generating Functions for Sattolo’s Algorithm
In 1986 S. Sattolo introduced a simple algorithm for uniform random generation of cyclic permutations on a fixed number of symbols. Recently, H. Prodinger analysed two important random variables associated with the algorithm, and found their mean and variance. H. Mahmoud extended Prodinger’s analysis by finding limit laws for the same two random variables.The present article, starting from the ...
متن کاملThe Basic Theorem and its Consequences
Let T be a compact Hausdorff topological space and let M denote an n–dimensional subspace of the space C(T ), the space of real–valued continuous functions on T and let the space be equipped with the uniform norm. Zukhovitskii [7] attributes the Basic Theorem to E.Ya.Remez and gives a proof by duality. He also gives a proof due to Shnirel’man, which uses Helly’s Theorem, now the paper obtains a...
متن کاملOn a Family of 2-Variable Orthogonal Krawtchouk Polynomials
We give a hypergeometric proof involving a family of 2-variable Krawtchouk polynomials that were obtained earlier by Hoare and Rahman [SIGMA 4 (2008), 089, 18 pages] as a limit of the 9− j symbols of quantum angular momentum theory, and shown to be eigenfunctions of the transition probability kernel corresponding to a “poker dice” type probability model. The proof in this paper derives and make...
متن کاملEffectiveness of Acceptance and Commitment Therapy (ACT) in Relapse Prevention in Methamphetamine Addict Patients
Background: Drug abuse has become one of the major problems in society and has become more prevalent among young people. The aim of this study was to evaluate the effectiveness of acceptance and commitment therapy (ACT) in relapse prevention in methamphetamine-dependent patients. Materials and Methods: In this study, a single-case experimental design with a linear asynchronous base line was us...
