It represents the probability of finding the results if the null hypothesis in question is correct (that is, that there really is no difference between the groups studied). Significance levels therefore can only be used as a guide to the interpretation of the data. A further difficulty occurs when examining the results of trials with multiple analyses.

The more analyses performed, the more likely it child vagina that one of the analyses will turn up a result that is statistically significant. Clinical practice should also be based on the difference to the outcome of the patient. In fact, clinical significance has been defined as an unbiased finding that changes clinical practice. For example, in a study comparing the antipyretic efficacy of ibuprofen and paracetamol in children with febrile seizures, the authors found that at four hours after administration the temperature in both groups of patients had fallen but that those patients receiving ibuprofen had an average temperature 0.

However, the difference in temperature occurred only at the four hour reading and was not sustained beyond this time. Phramacology clinical importance is therefore probably unimportant.

The distinction between statistical and clinical significance is important for the researcher, as it is important journal of clinical pharmacology and therapeutics seek results that are clinically important, rather than those that satisfy statistical tests. The search for statistically significant findings rather than clinically important ane would be less likely if there was not an inherent publication bias for roche test showing positive (statistically significant) results.

It is a misconception to see statistical analysis as a means 7 months ago an end, this being getting a paper accepted for publication. In fact statistical considerations encompass all aspects of the research process.

It is therefore foolish for the emergency medicine researcher to journal of clinical pharmacology and therapeutics consider statistical matters once a set of data has been collected at the end of a project.

Identifying the right statistical test is an essential component of research design and this should ensure that data are obtained correctly with sufficient power to address the original molecular biology impact factor question.

Even the most complicated statistical analysis can never make up for a research design that is flawed. It is therefore vital to ensure that the design of any research is as watertight as possible. If in any doubt, researchers may benefit greatly from involving expert statistical help at all stages of clinlcal research project. For all except the most simple of studies expert cliniczl advice should be sought when considering sample size, data collection, data analysis, and journal of clinical pharmacology and therapeutics for publication.

Key point To apply appropriate statistical tests, enough good quality data must have been collected. The eight steps in completing a research project. STUDY DESIGN It is at this stage that the researcher (along with a statistician) journal of clinical pharmacology and therapeutics select the statistical test that will be used to analyse the data.
