In recent weeks the reputation of the World Health Organisation (WHO) has suffered a number of blows, as critics have accused it of bowing to political pressures rather than publishing unpalatable research findings.One instance emerged last week. A controversial new study which looked for links between lung cancer and passive smoking found that non-smokers married to or growing up with smokers were not at significantly more risk from lung cancer than anyone else. The research, commissioned by the WHO and co-ordinated by Rodolfo Saracci of the WHOs International Agency for Research on Cancer, involved a long study. Since it was one of the biggest single pieces of research conducted into the issue, its results were eagerly awaited by the medical world and lobby groups. But instead of being released with a fanfare, they were summarised in three short paragraphs and buried in a bulky WHO internal document.(adapted from "The Economist", mar 98)Which of the statements below is confirmed by the text?
