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
introductionOne of the key stages of wound healing is the phase of inflammation, which is a transitional process between hemostasis and wound healing. Each stage of the inflammatory-reparative process is characterized by its own value of the acidity of the wound bed. For example, in the acute stage of inflammation, the acidity of the medium in the wound bed decreases to pH 5.5-6. The chronic stage of the inflammatory process, on the contrary, is accompanied by an increase in pH to 8. To date, the effect of biomaterials containing components of the intercellular matrix of the human dermis on fibroblasts under acidosis and alkalosis has not been fully investigated.
aimThe aim of this study was to characterize the effect of bioplastic material based on collagen, hyaluronic acid, and elastin on the viability and proliferative activity of human fibroblasts in conditions simulating the acidity of acute and chronic wounds. MATERIALS AND
methodsBioplastic material was made according to the method described in RF patent no. 2722744. Adhesive properties and proliferative activity of human fibroblasts were assessed visually using fluorescent microscopy. The number of apoptotic and necrotic cells was assessed by flow cytometry (BD FACSCanto II) using the commercial FITC Annexin V Apoptosis Detection Kit I (BD Pharmingen). The strength, Young's modulus, and elasticity of the gels were determined on a TA.XT-plus texture analyzer (Stable Micro Systems, Great Britain).
resultsUsing the methods of luminescent microscopy and flow cytometry, we found that the cell viability (namely, adhesive properties and proliferative activity) decreases after incubation on condition mimic of physiological acidosis. We found that bioplastic material contributes to the preservation of adhesive properties, viability, and proliferative activity of fibroblasts in physiological acidosis conditions. The results obtained indicate that bioplastic material based on soluble dermis components can be used as a biologically active component of wound dressings to increase the effectiveness of reparative regeneration, especially in cases of excessive acute inflammation.
