1 · What the graph read from it

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.

2 · The registry

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

Exopolysaccharides (EPS) are polymers of high industrial value due to their wide range of uses, and their profitable and sustainable production is a constant challenge. The objective of this work was to conduct EPS production by Leuconostoc sp. LU1 using sweet potato (Ipomoea batatas) waste as a substrate, as well as its physicochemical and functional characterization. Leuconostoc sp. LU1, isolated from the gherkin fruit, was phenotypically characterized and phylogenetically analyzed. The effect of different pH levels, yeast extract, and sweet potato waste on biomass and EPS production was evaluated by simple factor analysis. The physicochemical characterization was performed using FTIR, TGA, NMR and HPLC techniques, while the functional properties determined were the water solubility index, water and oil retention capacity, and antioxidant capacity. Regarding the evaluated parameters, cultivation at pH 5, with 1.0 g L
