1 · What the graph read from it

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.

2 · The registry

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

Diabetic periodontitis (DPD) is a severe inflammatory complication characterized by accelerated destruction of periodontal tissues and dysregulated immune responses. Gingival fibroblast (GF)-macrophage interactions drive DPD progression, but the mechanisms linking hyperglycemia, mitochondrial dysfunction, and immune activation remain unclear. Single-cell sequencing analysis of diabetic gingival tissues revealed significant apoptotic activation of GFs, closely linked to mitochondrial dysregulation. Inflammation and metabolic stress disrupt mitochondrial quality-control pathways and promote the overproduction of reactive oxygen species, inducing defective mitophagy. Crucially, apoptotic GFs secrete thrombospondin-1 (THBS-1), which binds to the CD36 receptor on the surface of macrophages, triggering NF-κB-mediated M1 polarization and pro-inflammatory cytokine production. Molecular modelling demonstrated a high-affinity interaction between THBS-1 and CD36. Gene silencing of THBS-1 in GFs or CD36 in macrophages effectively inhibited these changes, confirming the specificity of this cellular crosstalk mechanism. These findings together indicate mediation of hyperglycemia-induced mitochondrial dysfunction through the promotion of GF apoptosis and subsequent THBS-1/CD36/NF-κB-signaling-dependent macrophage activation. Thus, enhanced mitophagy and modulation of the THBS-1/CD36 axis are promising therapeutic strategies to break the self-perpetuating cycle of inflammation and tissue destruction in DPD.
