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/purpose: Peroxisome proliferator-activated receptor γ (PPARγ) is a major transcription factor of energy metabolism-associated genes, and three PPARγ isoforms have been identified in periodontal tissues and cells. When energy metabolism homeostasis is affected by PPARγ downregulation in periodontal ligament fibroblasts (PDLFs), osteo/cementogenic abilities are markedly lost. Herein, we investigated whether PPARγ agonists promote periodontal tissue regeneration, and which PPARγ isoforms and metabolic pathways are indispensable for osteo/cementogenic abilities. Materials and methods: A PPARγ agonist was locally administered to regenerate murine periodontal tissue. The distinct functions of the PPARγ isoforms in PDLFs were assessed using an overexpression strategy. Candidate metabolic processes were searched using gene ontology analysis of PPARγ-knockdown PDLFs. Results: PPARγ agonists accelerated periodontal tissue regeneration. Full-length PPARγ overexpression specifically enhanced the osteo/cementogenic differentiation of PPARγ agonist-induced PDLFs. The isoprenoid metabolic process was the top-ranked downregulated metabolism-associated pathway following PPARγ knockdown; FPP and GGPP enhanced and suppressed PDLFs' differentiation, respectively. Gene expression analysis of human clinical periodontal tissues revealed that Conclusion: Preferable PPARγ agonistic actions depend on the full-length PPARγ isoform. FPP increased PDLFs' osteo/cementogenic abilities. Therefore, administering FPP and precisely controlling FDPS, GGPS1, and FDFT1 activities could be a novel strategy for accelerating periodontal tissue regeneration.
