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

This study aims to investigate the association between the expression of Oct-4 and the biological behavior or prognosis of cervical cancer. Serum-free suspension culture technology was used to select a suspension of microspheres that can stabilize clones. The tumorigenicity of the microsphere suspension was analyzed in NOD/SCID mice. Microarray analysis was used to detect the specific expression of genes in the microsphere suspension. The expression of Oct-4 was detected by immunohistochemistry, and the correlation between Oct-4 expression and clinical pathological prognostic indicators was analyzed in cervical cancer. The expression of the following genes was significantly different between the experimental and control groups: stem cell differentiation (CD44 and Oct-4), markers cell cycle regulators (APC), cell cycle regulators (MYC), and self-renewal markers (MYST2, NEUROG2, and SOX1). The expression of Oct-4 was significantly higher in cervical cancer tissues than in adjacent normal tissues and was significantly related to differentiation, clinical stage, and lymph node metastasis. The 5-year survival rate of patients with Oct-4-positive expression was lower than that of patients with Oct-4-negative expression (36.7 vs. 67.7 %, respectively; P=0.001). Cox regression analysis revealed that clinical stage, lymph node metastasis, and Oct-4 were independent prognostic factors in cervical cancer (P=0.031, 0.012, and 0.001, respectively). Our results showed that Oct-4 was highly expressed in cervical cancer stem cells; Oct-4 expression was associated with biological behavior and was an independent prognostic factor in cervical cancer. Therefore, it may represent a potential target for cervical cancer treatment.
