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
purposeThis study was designed to evaluate the in vitro and in vivo biocompatibility and osteointegration of plasma-sprayed hydroxyapatite (HA)-coated polyethylene terephthalate (PET) ligaments encapsulated with a simvastatin (SV)-chitosan (CS) composite.
methodsThis study compared the in vitro and in vivo bone responses to three different PET ligaments: SV/CS/PET-HA, CS/PET-HA and PET-HA. A field emission scanning electron microscope was used to characterize the morphology, and the in vitro SV release profile was analyzed. MC3T3 cells were cocultured with SV/CS/PET-HA, CS/PET-HA and PET-HA to test their biocompatibility using CCK-8 tests. Osteogenic differentiation was investigated by the expression of marker genes using qPCR. Osteointegration was performed by implanting the PET ligaments into the proximal tibia bone tunnels of male Sprague-Dawley rats for 3 weeks and 6 weeks. The bone-implant interface was evaluated by micro-computed tomography (micro-CT) and histological analysis.
resultsThe characteristic nanoporous structures mainly formed on the surface of the plasma-sprayed HA particles in the SV/CS/PET-HA and CS/PET-HA groups. The SV release test showed that the sustained release of simvastatin lasted for 25 days in the SV/CS/PET-HA group. The in vitro studies demonstrated that the SV/CS/PET-HA ligaments induced osteogenic differentiation in the MC3T3 cells, with higher mRNA expression levels of collagen-1, bone morphogenetic protein-2, osteocalcin and alkaline phosphatase than those in the CS/PET-HA and PET-HA ligament groups. The in vivo tests showed that both micro-CT analysis (bone mineral density and bone volume per total volume) and histological analysis (bone implant contact and interface area) revealed significantly higher peri-implant bone formation and less interface area in the SV/CS/PET-HA group than in the other groups.
conclusionThe SV-CS composite nanoporous structure was associated with the improved biocompatibility and osteogenic differentiation in vitro and enhanced osteointegration process in vivo of plasma-sprayed HA-coated PET ligaments.
