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
abstractAnthracycline-mediated cardiotoxicity is a common concern after lymphoma therapy, particularly in patients with high cardiovascular risk (CVR). In noncancer populations, coronary artery calcium scoring (CACS) effectively identifies individuals who may benefit from aggressive CVR modification to lower the risk of cardiovascular events. Emerging evidence suggests that CACS can also predict cancer therapy-related cardiotoxicity, potentially identifying candidates for cardioprotective strategies. Our study aimed to evaluate whether CACS obtained from pretreatment positron emission tomography (PET)/computed tomography (CT) scans could stratify cardiac event risk in patients with lymphoma receiving anthracycline-based chemotherapy. We enrolled 358 consecutive patients with lymphoma treated between 2012 and 2022, calculating the CACS from their pretreatment PET/CT. We reviewed medical records to identify pre-existing cardiac conditions, CVR, and posttreatment cardiac events, including coronary events, heart failure (HF), and arrhythmias. Logistic and Cox regression models were used to assess associations between CVR, CACS categories (CACS = 0, CACS 1-400, CACS >400), and new cardiac events. At a median follow-up of 27 months (95% confidence interval [CI], 22.3-31.7) in patients without cardiac history, 10% experienced posttreatment cardiac events (HF, 14; arrhythmias, 9; coronary event, 1; combination, 8). Patients with a CACS >0 had more events (21 total, 20% vs 11 total, 5.4% for CACS = 0; P < .001). Elevated CACS was independently associated with HF (CACS 1-400: odds ratio [OR], 3.73; 95% CI, 1.21-11.43; P = .022; CACS >400: OR, 5.43; 95% CI, 1.47-20.03; P = .011) and any cardiac event (CACS 1-400: OR, 2.48; 95% CI, 1.02-6.04; P = .045; CACS >400: OR, 3.28; 95% CI, 0.91-10.68; P = .029). CACS may effectively stratify patients with lymphoma at risk of cardiac complications, thereby identifying a group poised to benefit from targeted preventive strategies.
