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

α-L-fucosidase 1 (FUCA1) is a lysosomal enzyme that catalyzes the hydrolytic cleavage of the terminal fucose residue in breast cancer cells. FUCA1 mRNA levels were detected by real-time PCR, and there was a greater than 139-fold increase in FUCA1 mRNA expression in breast tumor samples compared with normal breast tissue samples (*P = 0.005, n = 236). Higher FUCA1 mRNA expression was preferentially detected in early-stage tumors (stage 0 to 2) compared with advanced-stage tumors (stage 3 to 4) (stage 0-1 versus stage 3, *P = 0.015; stage 0-1 versus stage 4, *P = 0.024). FUCA1 protein levels were higher in advanced-stage tumors concomitant with decreased fucosylated Lewis-x antigen expression, as evidenced using the immunohistochemical staining H-score method (*P < 0.001). Statistical analysis revealed that lower FUCA1 levels significantly predicted an inferior overall survival rate among triple-negative breast cancer (TNBC) patients compared with non-TNBC patients (*P = 0.009). Two stable FUCA1 siRNA knock-down MDA-MB-231 cell lines were established, and the results suggest that transient FUCA inhibition creates a selective pressure that triggers the metastasis of primary tumor cells, as detected by wound healing and invasion assays (*P < 0.01). The results suggest that FUCA1 may be a potential prognostic molecular target for clinical use, especially in TNBC patients.
