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 aim of this study was to develop and characterize some freeze-dried wafers based on collagen and two mucoadhesive polymers, namely, hydroxypropyl methylcellulose (HPMC) and Carbomer 940 (CBM). The wafers were obtained by lyophilization of the corresponding hydrogels, which were evaluated by circular dichroism in order to investigate mucoadhesive polymers' influence on collagen's secondary structure. The obtained freeze-dried wafers were characterized by FT-IR spectroscopy, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), contact angle measurements, and water uptake capacity. Furthermore, biocompatibility assessment was performed by evaluating the impact of freeze-dried wafer extracts on cell viability, morphology, and migration capacity. Circular dichroism showed more significant changes in the secondary structure of collagen associated with the addition of Carbomer 940. The FT-IR spectra displayed specific peaks for collagen and the two mucoadhesive polymers. SEM images illustrated a microporous structure for both collagen and Carbomer 940, while HPMC displayed a more sheet-like structure. The addition of HPMC increased the thermal stability of collagen, while Carbomer 940 had a negative impact on the samples' thermal stability. Contact angle measurements and water uptake capacity showed good hydrophilicity of the wafers. Except for CBM 100%, all samples supported the viability of human fibroblasts and did not have any inhibitory effect on cell migration capacity, demonstrating good biocompatibility, which is an essential attribute in developing drug delivery supports intended for mucosal applications.
