Publication Bias - Remedies

Remedies

Ioannidis' remedies include:

  1. Better powered studies
    • Low-bias meta-analysis
    • Large studies where they can be expected to give very definitive results or test major, general concepts
  2. Enhanced research standards including
    • Pre-registration of protocols (as for randomized trials)
    • Registration or networking of data collections within fields (as in fields where researchers are expected to generate hypotheses after collecting data)
    • Adopting from randomized controlled trials the principles of developing and adhering to a protocol.
  3. Considering, before running an experiment, what they believe the chances are that they are testing a true or non-true relationship.
    • Properly assessing the false positive report probability based on the statistical power of the test
    • Reconfirming (whenever ethically acceptable) established findings of "classic" studies, using large studies designed with minimal bias

Famous quotes containing the word remedies:

    The said doctor can easily practise upon a page, and, if he does well, he can use his remedies on my son.
    Catherine De’ Medici (1519–1589)

    But sure there is need of other remedies than dreaming, a weak contention of art against nature.
    Michel de Montaigne (1533–1592)

    Our remedies oft in ourselves do lie,
    Which we ascribe to heaven. The fated sky
    Gives us free scope, only doth backward pull
    Our slow designs when we ourselves are dull.
    William Shakespeare (1564–1616)
