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
The choice of inoculum for successful isolation and establishment of axenic lichen mycobiont culture is a key step towards eliminating endolichenic and lichenicolous fungi and other microbial contamination. The nutritional requirements of each lichen species are unique. This work reports on the isolation, phenotypic plasticity, growth and secondary metabolites from mycobiont culture of the pantropical lichen Platygramme caesiopruinosa. Media composition [Malt yeast extract (MY), Modified Murashige and Skoog (MMS) and Lilly and Barnett (LB) media] was optimized to determine nutritional requirements for optimal growth of this species as assessed by dry biomass and the occurrence of secondary metabolite. Furthermore, the role of different carbon sources in affecting growth, growth stages, phenotypic plasticity, biomass and spectrum of secondary metabolites produced of this mycobiont was examined. The molecular identity of the mycobiont culture was confirmed by amplifying mitochondrial small subunit (mtSSU) sequences. Cultures showed optimum biomass production in MY medium with 10% sucrose. The secondary metabolite profiles for each culture treatment were characterized using High-performance Thin-Layer Chromatography (HPTLC) and Gas Chromatography with Mass Spectrometric (GC-MS) analysis. The HPTLC spectral comparison, phenolic and iodine confirmatory analysis revealed the absence of phenolic metabolites and the presence of non-phenolic metabolites in mycobiont extracts, while GC-MS analysis revealed the biosynthesis of side chain fatty acids, hydrocarbons and sugar alcohol in mycobiont cultures treated with 10% supplemented sucrose as a carbon source.
