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 cancer is one of the most lethal malignancies, primarily due to late-stage diagnosis and limited therapeutic options. Cancer stem cells (CSCs) contribute to tumor heterogeneity, therapy resistance, and recurrence through activation of developmental pathways such as Hedgehog, Wnt, Notch, JAK-STAT, and Hippo. Identifying CSCs is therefore essential for understanding pancreatic ductal adenocarcinoma (PDAC) pathogenesis and advancing targeted therapies. This study compares the expression of key CSC-associated markers (CD44, CD117, OCT3/4, and c-Myc) in PDAC, fetal, and adult pancreas to elucidate CSC dynamics. Immunohistochemistry for CSC markers (CD44, CD117, OCT3/4, and c-Myc) was performed on PDAC tissues and control pancreatic samples (fetal pancreas 28-36 weeks and adult pancreas) to evaluate marker expression. Proliferative potential was assessed using CK7 and Ki-67 expression patterns. CD44 showed strong membranous and cytoplasmic expression in PDAC, moderate in fetal pancreas (epithelial/ductal regions), and minimal expression in adult tissue. CD117 was mainly restricted to stromal cells in PDAC, also present in fetal tissue but low in adults. c-Myc and Ki-67 were moderately expressed in PDAC, significantly higher than the control samples. CK7 demonstrated strong cytoplasmic staining in PDAC, moderate expression in adults, and weak expression in fetal samples. CD44 and c-Myc re-expression in PDAC supports their role as CSC-associated markers and potential drivers of tumor progression. CD117's stromal localization suggests tumor-stroma interactions. These findings highlight developmental reactivation of CSC markers in PDAC, with implications for early detection and targeted therapy.
