The content of the OxRisk website (including the risk calculators) is accurate according to the opinions of the authors of the calculators. The information and directions may or may not apply to specific individuals considered for assessment. The calculators provide a ‘best guess’ of likely outcomes based on current knowledge, but cannot provide an accurate prediction for each individual. Determination of appropriate application and scoring of the OxRisk calculators to specific cases and in specific jurisdictions requires the judgement of a clinician or criminal justice professional. OxRisk calculators are intended to be an adjunct to clinical decision-making.
