The trial found a lower incidence of colon cancer with bezafibrate (0.53 % vs 1.13 %), but the two-sided P value was 0.07 and the hazard ratio’s 95 % CI (0.20–1.10) crossed 1.0. The authors therefore stated that their data only “support the hypothesis regarding a possible preventive effect,” making the evidence suggestive rather than conclusive [Tenenbaum et al., 2008, PMID 18565233].
