The role of PPAR in fungal keratitis.
Review in Frontiers in immunology, 2024. 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
The treatment of fungal keratitis(FK) remains challenging due to delayed fungal detection and the limited effectiveness of antifungal drugs. Fungal infection can activate both innate and adaptive immune responses in the cornea. Fungi stimulate the production of oxidative stress-related biomarkers and mediate the infiltration of neutrophils, macrophages, and T cells. These cells can induce infiltration of cytokines, chemokines, and matrix metalloproteinases (MMPs), leading to corneal tissue damage and even corneal perforation. The signaling pathway regulates the expression of inflammatory cytokines in fungal keratitis. Immune inflammatory damage is the main mechanism of FK, and oxidative stress damage is also involved in this infection process. Peroxisome proliferator-activated receptor (PPAR) is a member of the nuclear hormone receptor superfamily, with different subtypes of PPAR a, PPAR β/δ, and PPARγ. PPARs play important roles in the antioxidant response, anti-inflammatory, lipid metabolism, neuroprotection, and immune regulation processes. PPAR γ can promote macrophage polarization and reduce oxidative stress damage by regulating ROS production. PPAR has made some progress in the treatment of eye diseases: PPARa agonists can inhibit diabetes keratopathy and corneal neuropathy. PPARa agonists inhibit early immature angiogenesis in corneal alkali burns and have potential therapeutic effects on inflammatory corneal angiogenesis. PPARs can control the progression of dry eye disease and improve the condition of meibomian gland dysfunction. Based on this, we explored the potential roles of PPARs in the treatment of FK.
