What we have

CONFOUNDING FACTORS

The Evidence

• Level one Single study

• Quality of evidence– Consort– Grade

Systematic Review

Meta-analysis

Why the unease ?

• Why is it some have no doubts

• Why is it some have massive doubts?

Medically unexplained symptoms

The reason we are uncomfortable

Miracle cure for back pain: Agony ended by everyday antibioticsCHEAP antibiotics could end the agony of back pain for millions of Britons for ever.

DAILY EXPRESS

Press reports before peer acceptance

• MMR studies

• Steroids in cord injury

• Hence our doubts

Magical thinking in improvement

Need for a science-based approach• Rigorous theory and methods

• Fully specify interventions and mechanisms

• How much evidence is needed

Problem: childbed fever

Vienna Maternity Institution: rates of puerperal fever 1841-1849

Intervention was right; theory was wrong

• The logic of hand-washing with chlorine was right (the technical intervention worked)

• But the big theory of resorption of cadaveric particles was wrong

• And the adaptive work was disaster

Why we should wait for further evidence

Conclusion

• MRI performed at 1-year follow-up in patients who had been diagnosed with sciatica and a herniated disc on MRI …… did not distinguish between those with a favorable outcome and those with an unfavorable outcome
