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

Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignancies, and early diagnosis and assessment may enhance the quality of life and survival of patients. The prognostic value of key family 2 cystatins subunit in PDAC patients remains unknown. The potential molecular roles of family 2 cystatins and related pathways were investigated using bioinformatics analysis. The relationship of family 2 cystatin expression levels and clinical outcomes of 112 patients with early‑stage PDAC were evaluated via univariate and combined survival analysis. A prognostic nomogram model was also constructed and gene set enrichment analysis was performed to investigate potential pathways in PDAC. The pathways, interaction networks, and Gene Ontology term analysis of the cystatin gene family were analyzed in the present study. Cystatin F (CST7) was identified as the key subunit of family 2 cystatins in survival analysis. PDAC patients who harbored a higher expression level of CST7 had a lower risk in overall survival (adjusted HROS=0.44, 95% CI=0.25‑0.77, P=0.004) and a longer survival time in various subgroups. The prognostic nomogram indicated that the CST7 expression model effectively predicted the outcomes of patients with early‑stage PDAC (predictive ability >0.75). In the gene set enrichment analysis, it was revealed that CST7 expression may be involved in immune regulation and be associated with cell adhesion. CST7 could be a useful biomarker for the prognostic prediction of early‑stage PDAC after pancreaticoduodenectomy.
