Circulating Plasma Circular RNAs hsa_circ_0001785 and hsa_circ_0079876 as Promising Noninvasive Diagnostic Biomarkers for Breast Cancer: A Case-Control Study.
Article in The breast journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
aimsBreast cancer (BC) is a major health concern for women, with early diagnosis essential for better health outcomes such as survival. While mammography is the gold standard screening tool, it is not without drawbacks. Circular RNAs (circRNAs), a class of noncoding RNAs, characterized by covalently closed loops missing 5' and 3' ends, offer stability in body fluids like plasma and are emerging as promising diagnostic biomarkers. Thus, the aim of this study was to investigate the plasma levels of hsa_circ_0001785 and hsa_circ_0079876 in BC patients compared to healthy controls to evaluate their potential for noninvasive BC detection.
methodsA total of 129 women participated in this study (81 BC patients who underwent surgery and 48 healthy controls based on mammography). The plasma levels of hsa_circ_0001785 and hsa_circ_0079876 were measured using quantitative reverse transcription polymerase chain reaction (qRT-PCR) following RNA extraction from plasma samples. The diagnostic value was assessed using the receiver operating characteristic (ROC) curve.
resultsA significant increase in the expression of both circRNAs was observed in BC patients compared with healthy controls (p value < 0.001). ROC curve analysis demonstrated that an area under the curve (AUC) for hsa_circ_0001785, hsa_circ_0079876, and their combination were 0.76 (sensitivity = 74%, specificity = 79%), 0.98 (sensitivity = 93%, specificity = 92%), and 0.98 (sensitivity = 93%, specificity = 92%), respectively.
conclusionPlasma levels of hsa_circ_0001785 and hsa_circ_0079876 are significantly elevated in BC patients, with hsa_circ_0079876 showing superior sensitivity and specificity compared to hsa_circ_0001785. These findings highlight hsa_circ_0079876 as a particularly promising diagnostic potential in a case-control setting for noninvasive BC detection.
