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 current study aimed to explore the effect and underlying mechanism of the purinergic receptor P2Y2 in regulating the loss of intestinal neurons and the intestinal neural crest in Hirschsprung's disease (HSCR). Western blotting was used to assess the expression levels of P2Y2 in colon tissues. An in vivo HSCR mouse model was established following treatment with benzalkonium chloride (BAC). We overexpressed or silenced P2Y2 in SH-SY5Y cells, and cell proliferation, migration, and invasion were subsequently investigated by CCK-8, wound healing, and transwell assays, respectively. Additionally, we implemented a xenograft model to assess the impact of P2Y2 on tumor growth as well as the expression of extracellular signal-regulated kinase (ERK). The results showed that the expression of P2Y2 protein in the colon tissues of patients with HSCR was lower than that in the normal colon tissues. P2Y2 expression is downregulated in the colon tissues of mice with HSCR. Additionally, P2Y2 silencing inhibited SH-SY5Y cell proliferation, invasion, and migration. Furthermore, adenosine 5'-triphosphate (ATP, a strong agonist of P2Y2)-induced P2Y2 overexpression enhanced the proliferation, invasion, and migration of SH-SY5Y cells. Immunofluorescence staining and western blot analysis revealed that P2Y2 silencing downregulated phosphorylated (p)-ERK in SH-SY5Y cells. In addition, treatment with PD98059, a p-ERK inhibitor, reversed the effects of ATP on SH-SY5Y cell proliferation, invasion, and migration. Finally, we demonstrated that P2Y2 silencing suppressed tumor growth and decreased p-ERK expression. Overall, the results of the present study suggest that P2Y2 plays an important role in HSCR pathogenesis. P2Y2 silencing inhibited the proliferation, invasion, and migration of nerve cells by suppressing the ERK signaling pathway. P2Y2 silencing could be considered an innovative and possible target for treating HSCR.
