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
backgroundBRCA1/2 genes play a critical role in genome stability and DNA repair. In animal models, loss of cardiomyocyte-specific BRCA1/2 is associated with DNA damage, apoptosis, cardiac dysfunction, and mortality following anthracycline exposure. However, whether these preclinical findings translate to humans remains unclear.
objectiveAssess the impact of germline BRCA1/2 (gBRCA1/2) status on anthracyclines-induced cardiotoxicity (AIC) in patients with early breast cancer and no prior anti-HER2 therapy.
methodsThis single-center retrospective/prospective cohort study focused on early breast cancer patients, treated with anthracycline-based chemotherapy in the neo/adjuvant setting, no prior anti-HER2 therapy, and known gBRCA1/2 status, normal baseline left ventricular ejection fraction (LVEF), and no previous cardiovascular disease. Follow-up assessments involved myocardial dysfunction blood biomarkers (MDBB), transthoracic echocardiography (TTE), and quality of life (QoL) questionnaires. The primary objective was LVEF changes comparing BRCA1/2 mutation carriers (gBRCA1/2m) vs non-carriers (gBRCA1/2wt). Secondary objectives included differences in MDBB and QoL.
resultsA total of 137 patients were included (103 gBRCA1/2wt and 34 gBRCA1/2m). Baseline characteristics were similar between groups. Compared to baseline, LVEF% reduction was -4.7[-12.0, 0.0] vs -9.5[-18.0, -5.0] in gBRCA1/2wt vs gBRCA1/2m, (P = .027). After adjusting for confounders, the difference in reduction in LVEF remained statistically significant at -4.5 [95%CI, -8.6, -0.4; P = .032]. No differences between MDBB (C-reactive protein, hsTnI, NT-proBNP, D-Dimer, ST-2, or Galectine-3) or QoL (MLHFQ and EQ5-D index) were detected.
conclusionsgBRCA1/2m patients could represent a higher-risk population for AIC. gBRCA1/2 status should be one of the factors to consider in deciding on adjuvant anthracycline necessity. This population could benefit from a cardio-oncology closer follow-up and cardioprotective strategies.
