Campaigners for greater transparency in medical science have reiterated calls for more to be done to avoid "medical research waste" after an investigation found that results from more than a fifth of clinical trials across five Nordic countries have never been made public.
A study found that results from 475 clinical trials in Denmark, Iceland, Finland, Norway, and Sweden — involving almost 84,000 participants — were never made public in any form.
Nonpublication of clinical trial results wastes public money, harms patients, and undermines public health, the researchers said.
