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: Coronary computed tomography angiography and coronary artery calcium score (CACS) are rapidly being adopted for the noninvasive assessment of coronary artery disease (CAD). One of the primary limitations of calcium imaging is the inability to assess obstructive lesions in the presence of a high calcium burden. Currently, there is no guidance on what level of coronary artery calcium indicates a high risk of obstructive CAD. We aimed to determine sex-specific CACS thresholds suggestive of obstructive CAD by comparing coronary angiography with adjunctive tools to available CACS information. Methods: From August 2018 to August 2023, we retrospectively analyzed 1799 consecutive patients' clinical characteristics, angiographic information, and available intracoronary physiological/anatomical testing at a single institution. We evaluated the sex-specific distribution of CACS and its specificity for identifying obstructive CAD at a threshold of 90%. Results: Baseline characteristics were similar between the obstructive (n = 1223) and nonobstructive (n = 576) CAD groups. A CACS of ≥1000 in women (HR, 2.81; 95% CI, 1.77-4.47; Conclusions: A CACS of ≥1000 in women and ≥1400 in men identifies obstructive CAD at 90% specificity. These thresholds should be prospectively validated and may potentially be used to guide the selection of patients who would benefit from intensification of medical therapy or invasive evaluation in the appropriate clinical context.
