Association between COMT polymorphism, labor anxiety, and analgesia in pregnant women.

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
backgroundCOMT gene polymorphism is associated with mental disorders and sensitivity to pain. In this study, we investigated the association between the COMT gene polymorphism and labor anxiety and analgesia in pregnant women. SUBJECTS AND
methodsA total of 425 pregnant women undergoing labor analgesia were selected from May 2016 to February 2018. The COMT gene polymorphism was detected through the PCR with restriction fragment length polymorphism technique before childbirth. According to a COMT genotype, the enrolled pregnant women were subdivided into the Val/Val (allele GG) group, the Met/Met (allele AA) group, and the Val/Met (allele GA) group. Then, the intervertebral space of all pregnant women was injected with 3 mL of 2% lidocaine +6 mL of 0.08% ropivacaine and 6 µg of fentanyl. Labor analgesia was administered as follows: 80 mg of 0.08% ropivacaine +100 µg of fentanyl + normal saline to 100 mL. The general characteristics of the women were examined and recorded. In addition, the State Anxiety Inventory (SAI), VAS, Ramsay sedation score, and epinephrine and norepinephrine levels were compared and analyzed.
resultsA total of 391 pregnant women were enrolled in this study; among these pregnant women, there were 180 pregnant women in the GG group, 132 in the GA group, and 99 in the AA group. The minor allele frequency of COMT polymorphism among these pregnant women was 32.8%. Compared with the GG group, the SAI and VAS scores were higher, the Ramsay sedation score was lower, and the epinephrine and norepinephrine levels were higher in AA and GA groups (
conclusionThe COMT gene polymorphism was associated with labor anxiety and analgesia among pregnant women, and the Val158Met mutation in the
