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
Paeoniflorin (PF) is one of the principal components of peony, a plant widely used in traditional Chinese medicine for its anti-inflammatory and immunomodulatory effects. Human β-defensin-2 (hBD-2) is an antimicrobial peptide that acts as the first line of defense against bacterial, viral, and fungal infections. This study aims to determine whether or not PF can regulate the expression of hBD-2 and its possible molecular mechanism in human bronchial epithelial cells (HBECs). Real-time quantitative reverse transcription PCR showed that PF can enhance the mRNA expression level of hBD-2 in a concentration- and time-dependent manner in HBECs. Further studies demonstrated that the mRNA and protein expression levels of hBD-2 were attenuated by the p38 mitogen-activated protein kinase (p38 MAPK) inhibitor SB203580, the extracellular signal-regulated kinase (ERK) inhibitor PD98059, and the nuclear factor kappa B (NF-κB) inhibitor (pyrrolidine dithiocarbamate (PDTC)). The phosphorylation of p38 MAPK, ERK, and c-Jun N-terminal kinase was detected by Western blot analysis, and the NF-κB translocation of 16HBECs after PF treatment was analyzed by immunofluorescence. These results support that PF upregulates hBD-2 expression in HBECs through the p38 MAPK, ERK, and NF-κB signaling pathways. These findings provide a new pharmacological mechanism of PF for the treatment of microbial infections by strengthening epithelial antimicrobial barriers.
