Clinical Observation of Gene Polymorphism of Olanzapine or Aprepitant in Prevention of CINV.
Article in Pharmacogenomics and personalized medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
objectiveThe present study aims to investigate the correlation between the gene polymorphisms of the multidrug resistance protein 1 (ABCB1), the intron region of transcriptional factor (GTF2E1) and catechol-
methodsAntiemetic treatment with 5 mg of olanzapine or aprepitant triplet therapy was conducted in 210 patients with malignancies receiving cisplatin multi-day chemotherapy. The general data on the patients were collected with the evaluation of the rate of complete protection (TP), complete remission (CR), complete control (TC), and time to first vomiting, the functional living index-emesis (FLIE) scale, and side effects in the acute and delayed phases. The DNA mass spectrometry detected the gene polymorphisms of ABCB1, GTF2E1, COMT, and DRD2, and the correlation with TP was analyzed.
results1) There were no statistically significant differences in the TP, CR, TC, time of first vomiting, and FLIE index at different phases between the 5mg of olanzapine group and the aprepitant group (P > 0.05). 2) The main side effect in the olanzapine group was drowsiness (P = 0.00), and in the aprepitant group was constipation (P = 0.02). 3) The distributions of each genotype were in the Hardy-Weinberg (H-W) equilibrium. Univariate analysis showed that in the olanzapine group, delayed-phase TP was correlated with the ABCB1 rs1045642 non-TT (P = 0.01) genotype.
conclusionThe present study revealed that females and the rs1045642TT genotype were independent risk factors for delayed-phase CINV in the northern Chinese population, which provided a scientific basis for subsequent CINV-related analysis of high-risk factors in Chinese patients.
