title: From evidence to conclusions in psychiatric research.
abstract: OBJECTIVE
  To identify problems in the derivation of conclusions from evidence in psychiatry research.
  
  
  METHODS
  The scientific model of falsificationism is described as determining the logical requirements for proving conclusions from research evidence. Common types of problematic conclusions are identified, and examples from the current research literature are given.
  
  
  RESULTS
  Poorly formed conclusions are based on inadequate hypotheses, ambiguously phrased, blind to negative findings, fallacious in logic, or neglectful of alternative explanations.
  
  
  CONCLUSIONS
  The risks of accepting poorly formed conclusions are premature closure of scientific investigations, poor basis for decisions in psychiatric practice, and provision of misinformation to patients. It is recommended that practitioners be attentive to this aspect of critically appraising research.
