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 metabolism of posaconazole is mediated mainly by uridine 5'-diphospho-glucuronosyltransferase (UGT) enzymes, especially UGT1A4. The aim of this study was to investigate the effects of genetic polymorphisms on the posaconazole plasma concentration (PPC). This prospective study was conducted from September 2014 to August 2016. We enrolled patients with acute myeloid leukemia or myelodysplastic syndrome treated with posaconazole oral suspension (200 mg) three times daily for fungal prophylaxis. The patients were examined for the multidrug resistance gene 1 3435C>T and 2677G>T/A variations and the UGT1A4*3 allele by direct sequencing of DNA from peripheral whole-blood samples. We defined poor absorbers to be those with PPCs of <200 ng/ml and the optimal PPC to be ≥700 ng/ml on day 8. The associations between genetic polymorphisms and the PPC were evaluated using multivariate logistic regression analysis including clinical variables. During the study period, 132 patients were enrolled. Six patients (4.5%) were defined as poor absorbers, and 49 patients (37.1%) did not reach the optimal PPC on day 8. In multivariate analysis, the independent risk factors for a poor absorber were at least one UGT1A4*3 allele (adjusted odds ratio [aOR], 18.81; 95% confidence interval [CI], 1.09 to 324.44;
