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
We investigated DNA methylation and polymorphism in the methylated DNA using AFLP based methylation-sensitive amplification polymorphism (MS-AFLP) markers in ecotypes of Jatropha curcas L. growing in similar and different geo-ecological conditions. Three ecotypes growing in different geo-ecological conditions with environmental heterogeneity (Group-1) and five ecotypes growing in similar environmental conditions (Group-2) were assessed. In ecotypes growing in group-1, 44.32 % DNA was methylated and of which 93.59 % DNA was polymorphic. While in group-2, 32.27 % DNA was methylated, of which 51.64 % DNA was polymorphic. In site 1 and site 2 of group-1, overall methylation was 18.94 and 22.44 % respectively with difference of 3.5 %, while overall polymorphism was 41.14 and 39.23 % with a difference of 1.91 %. In site 1 and site 2 of group-2, overall methylation was 24.68 and 24.18 % respectively with difference of 0.5 %, while overall polymorphism was 12.19 and 12.65 % with a difference of 0.46 %. The difference of methylation percentage and percentage of methylation polymorphism throughout the genome of J. curcas at site 1 and 2 of group-1 is higher than that of J. curcas at site 1 and 2 of group-2. These results correlated the physico-chemical properties of soil at these sites. The variations of physico-chemical properties of soil at Chorwadla (site 1 in group-1 and site 2 in group-2) compared to the soil at Brahmapur (site 2 in group-1) is higher than that of soil at Neswad (site 1 in group-2). The study suggests that these homologous nucleotide sequences probably play important role in ecotype adaptation to environmental heterogeneity by creating epiallelic variations hence in evolution of ecotypes/clines or forms of species showing phenotypic/genotypic differences in different geographical areas.
