Norwegian research should be held to very similar standards to the UK though whereas that doesn't necessarily hold true for research conducted in a lot of countries.
My point was that the same kind of thing and worse is happening all the time when it comes to health research and all over the globe. I just know more about UK research being based here so useful to compare.
It's really not uncommon that researchers get around a lack of ethics approvals by exploiting a loop hole.
They call the research a service evaluation or an audit (like these researchers) and then claim not to need ethics approval.
Or they don't get approval from one ethics committee so they go to a second one.
Research fraud is a massive issue.
"Mol, like Roberts, has conducted systematic reviews only to realise that most of the trials included either were zombie trials that were fatally flawed or were untrustworthy. What, he asked, is the scale of the problem? Although retractions are increasing, only about 0.04% of biomedical studies have been retracted, suggesting the problem is small. But the anaesthetist John Carlisle analysed 526 trials submitted to Anaesthesia and found that 73 (14%) had false data, and 43 (8%) he categorised as zombie. When he was able to examine individual patient data in 153 studies, 67 (44%) had untrustworthy data and 40 (26%) were zombie trials. Many of the trials came from the same countries (Egypt, China, India, Iran, Japan, South Korea, and Turkey), and when John Ioannidis, a professor at Stanford University, examined individual patient data from trials submitted from those countries to Anaesthesia during a year he found that many were false: 100% (7/7) in Egypt; 75% (3/ 4) in Iran; 54% (7/13) in India; 46% (22/48) in China; 40% (2/5) in Turkey; 25% (5/20) in South Korea; and 18% (2/11) in Japan. Most of the trials were zombies. Ioannidis concluded that there are hundreds of thousands of zombie trials published from those countries alone."
