A list of some of the key concepts:
Recognising an unreliable basis for a claim
Treatments can harm.
Anecdotes are unreliable evidence.
Association is not the same as causation.
Common practice is not always evidence-based.
Newer is not necessarily better.
Expert opinion is not always right.
Beware of conflicting interests.
More is not necessarily better.
Earlier is not necessarily better.
Hope may lead to unrealistic expectations.
Explanations about how treatments work can be wrong.
Dramatic treatment effects are rare.
Understanding whether comparisons are fair and reliable
Comparisons are needed to identify treatment effects.
Comparison groups should be similar.
Peoples’ outcomes should be analysed in their original groups.
Comparison groups should be treated equally.
People should not know which treatment they get.
Peoples’ outcomes should be assessed similarly.
All should be followed up.
Consider all the relevant fair comparisons.
Reviews of fair comparisons should be systematic.
Peer review and publication does not guarantee reliable information.
All fair comparisons and outcomes should be reported.
Subgroup analyses may be misleading.
Relative measures of effects can be misleading.
Average measures of effects can be misleading.
Fair comparisons with few people or outcome events can be misleading.
Confidence intervals should be reported.
Do not confuse ‘statistical significance’ with‘importance’.
Do not confuse ‘no evidence of a difference’ with ‘evidence of no difference
