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
purposeCarriers of BRCA1/2 mutations are at high lifetime risk of breast cancer (BC); however, the BC onset broadly vary in individual patients. Recently, polyglutamine (poly-Q) repeat length polymorphism of the amplified in breast cancer 1 (AIB1) gene was analyzed as a risk factor influencing BC onset in BRCA1/2 mutation carriers with contradictory results.
methodsWe genotyped AIB1 poly-Q repeat in 243 BRCA1/2 mutation carriers, 61 patients with familial BC (negatively tested for the presence of BRCA1/2 mutation), 221 patients with sporadic BC, and 176 non-cancer controls using denaturing high-performance liquid chromatography and statistically evaluated the effect of AIB1 poly-Q repeat length polymorphism on BC onset.
resultsHaving used previously published statistical analyses of AIB1 poly-Q repeat length (≥28 and ≥29 repeat cutpoints or analysis of AIB1 poly-Q repeat length as continuous variable), we did not find any association between AIB1 poly-Q repeat length and BC development in analyzed BC groups. However, the analysis of individual genotypes revealed that AIB1 genotype consisting of 28/28 glutamine repeats served as a protective factor in BRCA1 mutation carriers (HR = 0.64; 95% CI 0.41-0.99; P = 0.045) and as a risk factor in carriers of mutation in exon 11 of the BRCA2 gene (HR = 3.50; 95% CI 1.25-9.78; P = 0.017).
conclusionsOur results confirm that AIB1 poly-Q repeat length polymorphism does not influence the BC risk in general but suggest that the specific AIB1 genotypes should be considered in patients with BC carrying mutation in the BRCA1/2 genes.
