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
In the present study, we have obtained one dwarf mutant (bnaC.dwf) from the Brassica napus inbred line T6 through chemical mutagen ethyl methanesulfonate (EMS). We have determined the phenotypic effects and genetic characteristics of dwarf mutant (bnaC.dwf). The dwarf mutant was insensitive to exogenous GA(3) for plant height, suggesting that it is significantly playing a crucial role in the gibberellins response pathway. Genetic analysis revealed that one recessive gene is responsible for controlling the phenotypic expression of dwarf mutant. Amplified Fragment Length Polymorphism (AFLP) technique was applied for selecting markers linked to the BnaC.DWF gene which assisted in screening of dwarf and normal individuals in the BC(4) population. We have screened 1,024 primer combinations and then identified nine AFLP markers linked to the BnaC.DWF gene. Identification and linkage of the markers were carried out by analysing 2,000 individuals from a larger population of the BC(4). Two markers EA10MC09 and EA12MC02 were located on the flanking region of the BnaC.DWF gene at a distance of 0.2 and 0.05 cM, respectively. Four AFLP markers EA09MG05, EA02MC07, EA01MC01 and EC04MC07 were successfully converted into Sequence Characterised Amplified Region markers namely SCA9G5, SCA2C7, SCA1C1 and SCC4C7. We further integrated BnaC.DWF linked Simple Sequence Repeat markers into two populations (Piquemal et al. Theor Appl Genet 111:1514-1523, 2005; Cheng et al. Theor Appl Genet 118:1121-1131, 2009). BnaC.DWF was mapped to the linkage region N18. The molecular markers developed from these investigations will greatly accelerate the selection process for developing dwarf varieties in B. napus by Marker Assisted Selection and genetic engineering.
