Publication Type Meeting Abstract
Abstract/Notes Excerpt: Pain is a subjective experience. For this reason, all currently used pain scoring systems must be regarded as giving only an indication of the pain perceived by an individual. Furthermore, statistical analysis relies on introducing an artificial numerical equivalents (or categorical labels) which can then be subjected to mathematical analysis. This is flawed as it does not truly reflect the subjective experience of pain. Does doubling the pain score mean the pain suffered has twice the intensity?

Objective measurements, such as the level of functioning of a patient, can be analysed and give reproducible data and are therefore superior in terms of absolute analysis.

The double-blind randomised controlled trial is the gold standard for obtaining data for statistical analysis. A ‘P’ value of below 0.05 is taken to be the threshold for indicating significant validity for a finding. However, there is, by definition, a 1:20 probability that this finding can happen by chance even though there is no difference between the groups in reality. Furthermore, 0.05 is only valid if two groups are being compared. If larger numbers of groups are included in the analysis the P value must be further reduced (e.g. to 0.016 for three groups.
