p.189-191
Limited effects

PART I 1963-2005: 10 randomised trials of mammographic screening

p.192
3 trials only, totalling 130 000 women, offer strong evidence. None showed a statistically significant reduction in overall mortality or breast cancer deaths

PART II Meta-analyses of mammography screening trials: inconsistent results

p.192-193
There is no strong evidence from meta-analysis supporting the use of mammographic screening to reduce overall mortality. There is weak evidence that mammographic screening reduces breath cancer deaths in women aged 40 to 74

Screening mammography

p.192-193
Not very favourable risk-benefit balance

PART III Mammographic screening and age

p.193
Age based analysis provides no convincing data favouring screening

PART IV Also in the balance: aggressive treatments, adverse effects

p.193
Problematic historical comparisons, adverse effects of mammography, and false negatives should be kept in mind. Available practice guidelines sometimes disagree

PART V Conclusions: not very favourable risk-benefit balance

p.193
The risk-benefit balance seems unfavourable in women (general population) less than 49; inadequately established between 50 and 69; not established after 69

Patients at high cardiovascular risk: excess mortality of about 1.6% on aspirin + clopidogrel

p.194
A disturbing trial

Acute myocardial infarction: aspirin + clopidogrel reduce mortality by about 0.5%

p.194
Short-term benefits

Headache and acupuncture

p.195
Chinese acupuncture no better than sham acupuncture, but both methods seem better than doing nothing

Reprehensible

A publicly accessible trial registry could help

French authorities
