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
Fatty acid desaturases are responsible for the insertion of double bonds into pre-formed fatty acid chains in reactions that require oxygen and reducing equivalents. In this study, genes for FAB2, FAD2-2, FAD6 and SLD1, were cloned from peanut (Arachis hypogaea L.). The ORFs of the four genes were 1,221, 1,152, 1,329 and 1,347 bp in length, encoding 406, 383, 442 and 448 amino acids, respectively. The predicted amino acid sequences of AhFAB2, AhFAD2-2, AhFAD6, AhSLD1 shared high sequence identity of 79, 76.2, 73.4 and 61% to the corresponding ones in Arabidopsis, respectively. Heterologous expression in yeast was used to confirm the regioselectivity and the function of AhFAD2-2 and AhFAD6. Linoleic acid (18:2), normally not present in wild-type yeast cells, was detected in transformants of these two genes. Quantitative real-time RT-PCR analysis indicated that the transcript abundances of AhFAB2 and AhFAD2-1 were higher in seed than that in other tissues examined. On the other hand, transcript of AhFAD2-2, AhFAD6 and AhSLD1 showed higher abundances in leaves. In addition, these five genes showed different expression patterns during seed development. These results indicated that the five genes may have different biochemical functions during vegetative growth and seed development.
