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
Objectives: Apatinib has been reported to be a promising treatment for sorafenib-resistant hepatocellular carcinoma (HCC) patients. However, the underlying mechanism remains ambiguous. The study aimed to explore the efficacy of apatinib in sorafenib-resistant HCC and the underlying mechanism both Methods: After observing epithelial-mesenchymal transformation (EMT) changes in HepG2 and HepG2/Sorafenib cells, we treated them with varying concentrations of apatinib to assess its impact on sorafenib-resistant HCC. Subsequently, specific inhibitors of c-Jun N-terminal kinase (JNK, SP600125) and extracellular signal-regulated kinase (ERK, PD98059) were introduced to investigate whether apatinib influenced sorafenib-resistant HCC via modulation of the epidermal growth factor receptor (EGFR)/JNK/ERK signaling pathway Results: The HepG2/Sorafenib cells exhibited greater resistance to sorafenib compared to HepG2 cells, and sorafenib-resistant HCC was characterized by EMT changes. Apatinib demonstrated concentration-dependent inhibition of biological behaviors in HepG2/Sorafenib cells, with minimal impact on HepG2 cells. Additionally, apatinib had a pronounced effect on the expression of EMT-related proteins in sorafenib-resistant cells similar to that in sorafenib-sensitive cells. Furthermore, there was a dose-dependent reduction in the expression of proteins associated with the EGFR/JNK/ERK pathway in apatinib-treated groups. Notably, SP600125 and PD98059 contributed to the inhibition of EMT and EGFR/JNK/ERK pathway-related proteins by apatinib in sorafenib-resistant HCC. Conclusion: Apatinib potentially hindered the progression of sorafenib-resistant HCC by suppressing both EMT and the EGFR/JNK/ERK pathway.
