1 · What the graph read from it

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.

2 · The registry

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

Lysyl oxidase (LOX) family genes, particularly lysyl oxidase-like protein 2 (LOXL2), have been implicated in carcinogenesis, metastasis, and the epithelial-to-mesenchymal transition (EMT) in various cancers. This study aimed to explore the clinical implications of LOXL2 expression in pancreatic cancer (PC) in the context of EMT status. LOX family mRNA expression was measured in PC cell lines, and LOXL2 protein levels were examined in surgical specimens resected from 170 patients with PC. Higher LOXL2 expression was observed in cell lines from mesenchymal type PC than in those from epithelial type PC. A significant correlation between LOXL2 expression and the EMT status defined based on the expression of E-cadherin and vimentin was observed in surgical specimens (P < 0.01). The disease-free survival and overall survival rates among patients with low LOXL2 expression were significantly better than those among patients with high LOXL2 expression (P < 0.001). According to the multivariate analysis, high LOXL2 expression (P = 0.03) was a significant independent prognostic factor for patients with PC. Additionally, LOX inhibition significantly decreased PC cell proliferation, migration, and invasion in vitro. In conclusion, LOXL2 expression is potentially associated with PC progression, and LOXL2 expression represents a biomarker for predicting the prognosis of patients with PC who have undergone complete resection.
