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
backgroundAtherosclerosis of the aorta and coronary arteries is still one of the major causes of death. We recently reported obesity paradox between body mass index and atherosclerosis of the aortas (AA) in morbidly obese decedent patients. The cause of this obesity paradox is unknown. The aim of the present study was to carry out genomic microarray analysis to determine gene expression profiles in the aortas of morbidly obese decedents with either mild or severe atherosclerosis of the aorta.
methodsMicroarray studies using Affymetrix GeneChips Clariom D Human array chips were performed on the aortas obtained from 6 morbidly obese decedents, 3 of whom had minimal AA and 3 who had severe disease.
resultsGroup 1 (severe AA) and group 2 (mild AA) included 3 patients each. The patients were matched by age and body mass index. There were significant (P<0.005) differences in the expressions of 1067 genes between groups 1 and 2, including 602 upregulated and 465 downregulated genes.
conclusionsOur data show significantly different gene signatures between morbidly obese decedents who have mild or severe AA, suggesting that genetic factors may be important contributors to the obesity paradox as it relates to aortic atherosclerosis. Further studies are warranted to define differences in protein expression in the aortas of these 2 groups to further elucidate the cause of this obesity paradox.
