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.

Abstract
The phosphatidylinositol 3-kinase (PI3 K)/Akt signaling pathway is one of the most commonly mutated pathways in breast cancer. To date, there has been no study on polymorphism of phosphatidylinositol-3,4-bisphosphonate 3-kinase, catalytic subunit alpha (PIK3CA) gene microsatellites and their link with breast cancer risk. In the present study, we investigate the guanine-thymine (GT) dinucleotide repeat polymorphism in intron 1 of PIK3CA gene in a cohort of 200 breast cancer patients and 200 healthy individuals and its link to the risk of developing breast cancer. The results of this study demonstrate that PIK3CA gene allele distribution in Isfahan population varies between 13 and 20 repeats. GT14 and GT16 were the most common allele present in patients, and GT17 was the most common allele in controls. Women with one or two alleles shorter than 17 GT repeat have a significantly higher risk of developing breast cancer [Odds ratio (OR) 3.6, p = 0.00001 and OR 3.98, p = 0.000001, respectively], in contrast, women with one or two alleles longer than 16 are at lower risk of breast cancer. This result suggests a potential role for this microsatellite as a predictive marker of breast cancer risk in Iranian women.
