The review
Who took part
The 19 trials had about 4,200 adults in all, and 16 of them were pooled. Typical age was about 43, about seven in ten were women, and the illnesses included diabetes, HIV and high blood pressure.
What they did
Health workers, most of them trained in this style of talk, met patients face to face or by phone. How often and how long they met varied, and in most trials the other group had usual care.
What happened
The gain was very small, from 16 trials after one trial that differed a lot from the rest was left out. With all 17 trials the gain was a little bigger. Face-to-face delivery and talk-only programmes seemed better, but the summary and results give different numbers.
