In vivo behavior of a collagen-coated nano-hydroxyapatite enriched polycaprolactone membrane in rat mandibular defects.

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
backgroundThis research investigated the ability of fabricated collagen (COL) coated nano-hydroxyapatite (nHA) enriched polycaprolactone (PCL) membrane to facilitate new bone formation (NBF) and its biocompatibility.
methodsUnilateral mandibular angulus defects of 28 female 12-week-old long Evans rats were created with a trephine bur with 5 mm in diameter and divided into two groups. While the test group was treated with the membrane (M-1, M-2), the control was left as self-healing (C-1, C-2) and sacrificed at 2nd (M-1, C-1) and 8th week (M-2, C-2) postoperatively. The mandibular bone of the rats was evaluated histopathologically. Density of the regenerated bone was evaluated with PET/CT.
resultsHistopathologically, NBF which started from the periphery of the defect had rich cellular character in M-1. Significantly higher NBF was found in M-2 when compared to M-1 (P=0.003). Furthermore, significantly lesser degree of inflammation was found in M-2 when compared to M-1 (P<0.05).
conclusionThis study suggests that the novel COL-coated nHA-enriched PCL membrane can serve a promising design for tissue engineering as guided bone regeneration in alveolar defects.
