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: Ropivacaine is widely used for clinical anesthesia and postoperative analgesia. However, the neurotoxicity induced by ropivacaine in a concentration- and duration-dependent manner, and it is difficult to prevent neurotoxicity. Osthole inhibits phosphodiesterase-4 activity by binding to its catalytic site to prevent cAMP hydrolysis. The aim of this present study is to explore the precise molecular mechanism of osthole-mediated inhibition of neurotoxicity induced by ropivacaine. Methods: SH-SY5Y cell viability and apoptosis were measured in different concentration and duration. Protein concentration was determined in each signaling pathway. The molecular mechanism of osthole-mediated inhibition of ropivacaine-caused neurotoxicity was evaluated. Results: The study demonstrated that osthole inhibits SH-SY5Y cells neurotoxicity in a duration- and concentration-dependent manner. Moreover, ropivacaine significantly increased the expression of caspase-3 by promoting the phosphorylation of p38. Osthole-induced upregulation of cAMP activated cAMP-dependent signaling pathway, sequentially leading to elevated cyclic nucleotide response element-binding protein levels, which inhibits P38-dependent signaling and decreases apoptosis of SH-SY5Y. Conclusions: This study display the evidence confirmed the molecular mechanism by which osthole amplification of cAMP-dependent signaling pathway, and overexpression of cyclic nucleotide response element-binding protein inhibits P38-dependent signaling and decreases ropivacaine-induced SH-SY5Y apoptosis.
