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
Drug-induced gingival enlargement (DIGE) is a side effect of ciclosporin, calcium channel blockers, and phenytoin. DIGE is a serious disease that leads to masticatory and esthetic disorders, severe caries, and periodontitis but currently has no standard treatment. We recently reported that nuclear receptor 4A1 (NR4A1) is a potential therapeutic target for DIGE. This study aimed to evaluate the therapeutic effects of n-butylidenephthalide (BP), which increases the expression of NR4A1, on DIGE. In this study, NR4A1 mRNA expression was analyzed in the patients with periodontal disease (PD) and DIGE. We evaluated the effect of BP on NR4A1 expression in gingival fibroblasts and in a DIGE mouse model. RNA sequencing (RNA-seq) was conducted to identify the mechanisms by which BP increases NR4A1 expression. The results showed that NR4A1 mRNA expression in the patients with DIGE was significantly lower than the patients with PD. BP suppressed the upregulation of COL1A1 expression, which was upregulated by TGF-β. BP also ameliorated gingival overgrowth in DIGE mice and reduced Col1a1 and Pai1 expression. BP also decreased Il1β mRNA expression in gingival tissue in DIGE. RNA-seq results showed an increase in the expression of several genes related to mitogen-activated protein kinase including DUSP genes in gingival fibroblasts stimulated by BP. Treatment with ERK and JNK inhibitors suppressed the BP-induced increase in NR4A1 expression. In addition, BP promoted the phosphorylation of ERK in gingival fibroblasts. In conclusion, BP increases NR4A1 expression in gingival fibroblasts through ERK and JNK signaling, demonstrating its potential as a preventive and therapeutic agent against DIGE.
