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 present study aimed to produce and characterize corn starch/carboxymethyl cellulose (TPC/CMC) films cross-linked with different concentrations of citric acid (CA). The films were obtained by solvent evaporation (casting solution) with 5, 10, 15, and 20% citric acid relative to the CMC mass (TPC/CMC-CA-0 to 20). They were qualitatively evaluated for visual aspects, swelling, moisture content, and solubility, and characterized by Fourier transform infrared spectroscopy (FTIR), thickness, and scanning electron microscopy (SEM). The results allowed us to evaluate the cross-linking effect promoted by citric acid. Visually, all films showed excellent optical transparency. FTIR spectroscopy demonstrated the formation of ester groups, indicative of cross-linking of the TPC-CMC films. SEM images revealed a homogeneous surface morphology without porosity in the films with CA. The addition of CA to the TPC-CMC films reduced water swelling, moisture absorption, and permeation. Additionally, the insertion of citric acid promoted an improvement in the tensile strength of TPC-CMC from 6.07 to 8.39 MPa for TPC-CMC/CA-15. This same trend was obtained with an increase of around 115% for the modulus in the TPC-CMC/CA-15 film compared to the film without CA. These results were due to cross-linking promoted by CA which produces a more cohesive material and thus increases the modulus and tensile strength. Thus, our results demonstrate that the cross-linking promoted by CA in TPC-CMC films has a profound influence on their water susceptibility and tensile properties.
