Study charts links between mobile phones, tumors
"Myung and colleagues at Ewha Womans University and Seoul National University Hospital in Seoul and the University of California, Berkeley, examined 23 published studies of more than 37,000 people in what is called a meta-analysis. They found results often depended on who conducted the study and how well they controlled for bias and other errors. "We found a large discrepancy in the association between mobile phone use and tumor risk by research group, which is confounded with the methodological quality of the research," they wrote in the Journal of Clinical Oncology."
