Article in Annals of translational medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Background: Composite scaffolds that maximize the advantages of different polymers are widely utilized in guided tissue regeneration (GTR). Some studies found that novel composite scaffolds composed of electrospun polycaprolactone/fluorapatite (ePCL/FA) actively promoted the osteogenic mineralization of various cell types Methods: In this study, ePCL/FA composite scaffolds were characterized and their effects on bone tissue engineering and repair of calvarial defects in rats were examined. Sixteen male Sprague-Dawley (SD) rats were randomly categorized into four groups: normal group (integral cranial structure without defect), control group (cranial defect), ePCL group (cranial defect repaired by electrospun polycaprolactone scaffolds), and ePCL/FA group (cranial defect repaired by fluorapatite-modified electrospun polycaprolactone scaffolds). At 1 week, 2 months, and 4 months, micro-computed tomography (micro-CT) analysis was performed to compare the bone mineral density (BMD), bone volume (BV), tissue volume (TV), and bone volume percentage (BV/TV). The effects of bone tissue engineering and repair were observed by histological examination (hematoxylin and eosin, Van Gieson, and Masson respectively) at 4 months. Results: In water contact angle measurement, the average contact angle for the ePCL/FA group was significantly lower than that for the ePCL group, indicating that the FA crystal improved the hydrophilicity of the copolymer. Micro-CT analysis revealed that the cranial defect had no significant change at 1 week; however, the BMD, BV, and BV/TV of the ePCL/FA group were significantly higher than those of the control group at 2 and 4 months. Histological examination showed that the cranial defects were almost completely repaired by the ePCL/FA composite scaffolds at 4 months compared to the control and ePCL groups. Conclusions: The introduction of a biocompatible FA crystal improved the physical and biological properties of the ePCL/FA composite scaffolds; thus, these scaffolds demonstrate outstanding osteogenic potential for bone and orthopedic regenerative applications.
