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
Single cell oils (SCO) are oils derived from microorganisms which have potential to hyperaccumulate intracellular lipids (called oleaginous) under some essential nutrient (nitrogen, phosphorous or sometimes sulphur) starvation and an excess of carbon. The present work investigates the influence of these key parameters (for triggering oleaginicity), i.e. carbon (C) and nitrogen (N) on oleaginous behaviour of an oleaginous isolate, with the objective of improving the lipid content and obtaining oils of applicative interest. Eleven yeasts were isolated from rotten fruits and a unique yeast from rotten apple was screened on the basis of its ~ 20% (of dry mass) lipid content (LC), trademark of oleaginicity under nitrogen-stressed culture conditions. Subsequent investigation on influence of C, N and w/w ratio of carbon source concentration (Cs) to nitrogen source concentration (Ns) was conducted on this isolate. The isolate was identified as a Deuteromycete-Geotrichum candidum. 4.8 g/l was found to be minimum N concentration and glucose as suitable C source for optimum balance between biomass and lipid content. The highest LC of 73.6% (172.5% higher compared to 27% LC at Cs/Ns 80/4.8) was obtained at Cs/Ns 150/4.8 with a lipid coefficient of 8.7 (g lipid/100 g substrate). While remarkably higher production economy (lipid coefficient of 28.45) was noted at Cs/Ns 100/4.8 with significant LC of 54.4% (~ 100% higher than at Cs/Ns 80/4.8). The derived oils were predominantly rich in medium-chain fatty acids (MCFA)-caprylic acid, rare in plant oils. G. candidum is a previously referred oleaginous species; however, for the first time this study illustrates its detailed oleaginous behaviour and lipid compositional characteristics with varying nutritional parameters. The work is a progressive contribution towards current and upcoming researches in field of SCOs. Compositional characteristics of derived oils, make it an important candidate for potential medical and nutritional applications in future.
