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
backgroundExisting studies suggest that nuclear paraspeckle assembly transcript 1 (NEAT1) is involved in the biological behavior of endothelial cells by regulating angiogenesis. Treatment of infantile hemangioma (IH) with propranolol (Pro) has been shown to block nuclear factor-κB (NF-κB)-mediated angiogenesis. However, the underlying mechanisms remain unclear.
methodsRNA sequencing (RNA-Seq) was used to compare potential genes in hemangioma-derived endothelial cells (HemECs) treated with Pro to those in the control group. NEAT1 was selected. NEAT1 expression was examined via RT-qPCR. The role of NEAT1 in HemECs was analyzed using wound healing and tube formation assays. The interaction between miR-194-5p and NEAT1 or tumor necrosis factor receptor-associated factor 6 (TRAF6) was verified by dual-luciferase assay.
resultsNEAT1 was elevated in proliferative tissues of IH patients. Moreover, NEAT1 knockdown suppressed the proliferation and migration of HemECs, mirroring the effects of Pro administration. Mechanistically, NEAT1 competitively binds to miR-194-5p and positively regulates the NF-κB pathway by increasing TRAF6 expression in vitro. In vivo, tumors gradually shrank following propranolol treatment, accompanied by an increase in miR-194-5p and a decrease in NEAT1, TRAF6/NF-κB pathway-related proteins, most notably in Pro plus dexamethasone.
conclusionNEAT1 regulates the TRAF6/NF-κB pathway in the pathogenesis of IH by inhibiting miR-194-5p, providing new insights for IH treatment. IMPACT: LncRNA NEAT1 knockdown suppressed the proliferation and migration of HemECs. LncRNA NEAT1 regulates the TRAF6/ NF-κB pathways by acting as a ceRNA of miR-194-5p in vitro. LncRNA NEAT1 participates in the pathogenesis of IH and may serve as a new target for propranolol treatment.
