New research looking at the success of clinical trials of stem cell therapy shows that, when trials appear to be more successful, more discrepancies in trial data are also evident.
Discrepancies were defined as two (or more) reported facts that could not both be accurate because they were logically or mathematically incompatible. For example, one trial reported that it involved 70 patients, who were divided into two groups of 35 and 80.
The researchers found eight trials that each contained over 20 discrepancies.
The meta-analysis of 49 randomized controlled trials of bone marrow stem cell therapy for heart disease in the British Medical Journal identified and listed over 600 discrepancies within the trial reports.
