PIK3CA and PTEN Genes Expressions in Breast Cancer.
Article in Asian Pacific journal of cancer prevention : APJCP, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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.
Who cites it
6 citing papers in PubMed, 1 synthesis or guideline pooled it, 16 citations in OpenAlex.

Abstract
Background: The phosphatidylinositol-3 kinase (PI3K) intracellular signaling pathway plays an important role in breast cancer. The current study aimed to evaluate the expressions of two main regulators of PI3K pathway; phosphatidylinositol-3- kinase catalytic subunit alpha as activator (PIK3CA), and phosphatase and tensin-homolog as inhibitor (PTEN), in breast carcinoma tissue, and compare with their expressions in adjacent normal breast tissue. Methods: A total of fifty female patients with breast carcinoma from surgical oncology unit of Alexandria-Main University Hospital were included in this study. The Quantitative Real Time PCR was used to quantify expressions of PIK3CA and PTEN. Results: PIK3CA mRNA expression was significantly increased in breast cancer tissues compared to normal breast tissues (P<0.001, Z=5.700), also PTEN mRNA expression was significantly higher in breast carcinoma tissue compared to normal breast tissue (P<0.001, Z=5.362). Conclusion: Increased the expressions of PIK3CA and PTEN mRNA in breast cancer tissue compared to normal breast tissue.
