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
This study reports the first example of crosslinking of carboxymethyl cellulose (CMC) and aliphatic diamines (CMCA) using a condensation agent, (4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methyl-morpholinium chloride (DMTMM)), to prepare highly functional films for food packaging application. The novelty of this work lies in the combination of diamine crosslinking and DMTMM activation to produce films with enhanced barrier and mechanical properties. Products were analysed by mono-/bi-dimensional NMR to prove the amide linkage and by the modification degree (MoD) for diamine quantification. The physical-chemical characteristics of the CMCA films were further determined by DSC, TGA, SEM, and ATR-FTIR, and the moisture content (MC%), moisture uptake (MU%), water vapour permeability (WVP), oil absorption ratio (OAR), and tensile strength (TS) evidenced the key role of DMTMM in the formation of strong covalent bonds between the carboxylate groups of CMC and the diamine, influencing the properties of CMCA films. When a COONa/ethylenediamine/DMTMM molar ratio of 6/1/2 was employed, the best WVP (2.63 ± 0.24 × 10
