Common variants of catechol-O-methyltransferase influence patient-controlled analgesia usage and postoperative pain in patients undergoing total hysterectomy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Catechol-O-methyltransferase (COMT) gene polymorphisms and haplotypes have been associated with both experimental and clinical pain phenotypes. In this prospective study, we investigated the association of three common polymorphisms with experimentally induced pressure pain, postoperative pain and amount of self-administered morphine in 973 patients who underwent scheduled total hysterectomy. DNA extracted from peripheral blood was genotyped for three COMT polymorphisms by Taqman assay or a PCR-based method. In the overall sample, rs4633 and rs4680 were significantly associated with morphine use, whereas rs4818 was associated with time-averaged pain scores. Statistically significant associations were found between COMT rs4633 and rs4680 genotypes and the amount of morphine self-administered through a patient-controlled analgesia pump. For rs4818, the only statistically significant association was with time-averaged pain scores. Haplotype analysis showed statistically significant association of the low pain sensitivity haplotype with time-averaged pain scores; and average pain sensitivity haplotype with total morphine and weight-adjusted morphine.
