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
purposePachygyria/agyria are congenital brain malformations characterized by presence of a few broad, flat gyri with thickened cortex, resulting from arrest of neuronal migration in early gestation. We are hereby describing diffusion tensor imaging findings in different histological layers of lissencephaly cortex in two children.
methodDTI in addition to conventional MR imaging was performed in two children on a 3 T MRI and post-processed with vendor supplied software to generate the fractional anisotropy, mean diffusivity and trace maps. Tractography was also performed to identify presence of tracts in the thickened cortex.
resultsDTI demonstrated the dysplastic multilayered cortex in cases of pachygyria/agyria; the thickened fourth layer and superficial layer demonstrated high anisotropy on diffusion tensor imaging.
conclusionDTI is a useful tool for identifying gross histological features of pachygyria-agyria complex. Superficial layer and thickened fourth layer demonstrate high anisotropy. Identification of anisotropy in the superficial layer has not been described in previous reports.
