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
Objectives: To study the risk of acute myocardial infarction (AMI) in patients with SSc in a population-based cohort. Methods: Using nationwide Swedish registers, we identified patients with incident SSc 2004-19 and age- and sex-matched comparators from the general population (1:10). Our primary outcome was incident AMI or death from incident AMI. We started follow-up from SSc diagnosis until the primary outcome, death from other cause than AMI, emigration or study end (31 December 2019). We estimated crude AMI incidence rate. We used flexible parametric models to explore the relative risk of AMI over time since diagnosis. We also used age as time scale to explore how AMI risk changes over increasing age. We also studied the outcomes of AMI in SSc compared with the matched comparators. Results: We identified 1579 patients and 16 064 comparators. The incidence rate of AMI was 75.2 (95% CI 58.8-94.6) per 10 000 person-years in patients with SSc and 37.5 (95% CI 34.0-41.3) in the comparators, median follow-up was 5.2 and 6.3 years, respectively. The adjusted hazard ratio (HR) was highest during the first year after SSc diagnosis (HR 3.1, 95% CI 2.0-4.6). In patients with SSc, the risk of AMI increased more rapidly with increasing age compared with the comparators. AMI in SSc was associated with higher risk of mortality (HR 2.7, 95% CI 1.6-4.4) but not 30-day readmission (HR 1.3, 95% CI 0.7-2.0) compared with the comparators. Conclusion: In line with previous studies, SSc is associated with a 2-fold increase in AMI incidence compared with the general population.
