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
backgroundFurcation defects are considered among the most challenging periodontal lesions to regenerate given the complexity of the periodontal apparatus, inaccessibility and the limited blood supply to the area. The aim of the current study was to create and characterize a novel ternary hydrogel composed of hyaluronic acid (HA), chitosan (CS) and polyvinyl alcohol (PVA) and to evaluate its potentials in periodontal regeneration of furcation defects in dogs. MATERIALS AND
methodsA composite hydrogel scaffold composed of hyaluronic acid, chitosan and polyvinyl alcohol was successfully prepared and characterized in terms of SEM, swelling and mechanical behaviors, FTIR analysis as well as biocompatibility assay and direct cell-scaffold interactions. In an in vivo study, thirty-two critical size class II furcation defects were created in eight mongrel dogs and randomly allocated to group I, hydrogel group and group II, negative control group. Histological analysis and histomorphometric evaluation of percentage of newly formed bone area were used to evaluate the regenerative potential of the novel hydrogel after one and three months, postoperatively.
resultsThe prepared hydrogel was cytocompatible, had proper degradation rate, water uptake and mechanical strength as well as ease of handling clinically. Histologic results of the hydrogel group revealed superior bone, periodontal ligament and cementum formation compared to the negative control group at both time points. The hydrogel group showed a statistically significant increase in the percentage of newly formed bone surface area compared to the negative control group.
conclusionsThe novel ternary hydrogel prepared using hyaluronic acid, chitosan and polyvinyl alcohol showed adequate cytocompatibility and mechanical properties. The in vivo results support that the novel scaffold might be effective for periodontal regeneration in furcation defects in dogs.
