Factors Determining the Antimicrobial Effectiveness of Chitosan: A Critical Analysis of the Impact of Molecular Weight and Degree of Deacetylation.

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
Despite chitosan's proven biocidal potential, there is a lack of consensus regarding the influence of its key physicochemical parameters, degree of deacetylation (DD) and molecular weight (MW), on its antimicrobial efficacy. The aim of this study was to quantitatively synthesize available literature data and provide an exploratory statistical analysis of the trends regarding the influence of chitosan DD and MW on the minimum inhibitory concentration (MIC). A PRISMA-guided literature review (2016-2026) across four major databases extracted 127 independent in vitro experiments, Gram-positive/negative bacteria and fungi. Physicochemical correlations were analyzed using multiple linear regression. Insoluble polymer fractions (here set as DD < 60%) critically interfere with MIC determination due to restricted diffusion and were strictly excluded from analyses. For the optimized group of soluble chitosans (
