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
The cytochrome P450 (CYP) 1A2 gene is involved in the metabolism of several carcinogens and clinically important drugs, generating a high potential for pharmacokinetic interactions. Since no data are available for Tibetan aborigines, the present study aimed to investigate the distribution of variant CYP1A2 alleles in a population living in Tibetan region of China. Genotyping analyses of CYP1A2 were conducted in 96 unrelated, healthy volunteers of Tibetan ancestry using direct sequencing assays. A total of 14 different CYP1A2 polymorphisms, including two novel variants (1690G>A and 2896C>T) in the intron region and a novel non‑synonymous one (795G>C, Gln265His) were detected. CYP1A2*1A (6.77%), CYP1A2*1B (58.33%) and CYP1A2*1F (14.58%) were the most frequent defective alleles identified in the sample. The frequencies of the prevalent genotypes CYP1A2*1A/*1B, *1B/*1B, *1B/*1F were 13.54%, 16.67% and 29.17%, respectively. In addition, the novel non‑synonymous variant 795G>C (Gln265His) was predicted to be benign by PolyPhen‑2 and SIFT tools. The present study provides useful information on the pattern of CYP1A2 polymorphisms in Chinese Tibetan population. The current results may have potential benefits for the development of personalized medicine in the Tibetan population.
