10 People invited to participate in weight watchers Take up the invitation 1 Attend all classes 2 Weight loss 5.4 kg 3 At 2 years people maintain their goal weight 4 At 5 years 4 (9 women and 1 man) maintain their goal weight 6 Do not attend the first class 2 Do not attend all of the classes At 1 year lose an average of 2.5 kg Don’t take up an invitation 1.Jolly et al (BMJ): the response rate to the invitation was 11.5% 2.Ahern et al (BMC Public Health): 54% of courses were completed 3.Ahern at al (BMC Public Health): median weight change was 5.4kg in those that completed the course 4.Lowe MR (BJN) The percentage of participants who remained below their goal wait at 2 and 5 years was 20.5% and 16.2% respectively Weight Watchers Most intervention don’t apply to the people we see in practice?

11 Insufficient evidence exist around most current interventions to determine if they are effective There were 14 studies (16 comparisons) with extractable data, of which 10 examined TCAs, 2 examined SSRIs and 2 included both classes, all compared with placebo. The nos. of participants in the intervention groups was 1364 and in the placebo groups 919. Nearly all studies were of short duration, typically 6-8 weeks. There was no dose information on SSRIs, and the authors were unable to comment on the appropriate duration of treatment for either TCAs or SSRIs.

13 For every 1000 patients treated 65 more will be alive at 1 month if treatment is administered in the first hour – the ‘golden hour’ – after symptom onset, compared with not giving thrombolysis 37 lives are saved for every 1000 patients treated in the 1–2 hour interval after symptom onset 26 lives are saved for every 1000 patients treated in the 2–3 hour interval after symptom onset 29 lives are saved for every 1000 patients treated in the 3–6 hour interval after symptom onset 20 lives are saved for every 1000 patients treated in the 7–12 hour interval after symptom onset.

14 There is a constant need to re-evaluate interventions “ Aspirin for everyone older than 50?”
