Prognostic value of SYNTAX score, intravascular ultrasound and near-infrared spectroscopy in coronary disease: 12-year follow-up of ATHEROREMO.
Article in Clinical research in cardiology : official journal of the German Cardiac Society, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimsThis study aims to investigate the very long-term predictive value of the SYNTAX score and plaque characteristics derived by intravascular ultrasound (IVUS) as well as near-infrared spectroscopy (NIRS), for all-cause mortality in patients with low to intermediate complex coronary artery disease.
methodsWe evaluated 581 patients with chronic or acute coronary syndrome from the European Collaborative Project on Inflammation and Vascular Wall Remodeling in Atherosclerosis (ATHEROREMO) cohort. Flow-limiting lesions were treated with intracoronary stenting. IVUS-VH (n = 581) and NIRS (n = 195) images were obtained in a non-culprit segment ≥ 40 mm. Cox models were applied to relate pre-PCI SYNTAX score and plaque characteristics to very long-term all-cause mortality. Adjusted hazard ratios (aHR), corrected for cardiovascular comorbidities and risk factors, are reported per doubling of the corresponding variable.
resultsMean (standard deviation) age was 62 (11) years; 76% were men; median SYNTAX score was 9.0 (25th-75th percentile 4.0-15.0). Median follow-up was 12.8 (25th-75th percentile 10.1-13.4) years, and 177 cases of all-cause mortality occurred. SYNTAX score (aHR 1.25, 95% confidence interval [CI] 1.05-1.48; p = 0.012) and percentage dense calcified plaque (aHR 1.21 [1.02-1.42]; p = 0.026) were associated with increased mortality risk, while fibrous plaque (aHR 0.54 [0.34-0.87]; p = 0.011) was related to reduced risk. NIRS features were not associated with very long-term mortality.
conclusionAngiography-based SYNTAX score and IVUS-VH-defined fibrous and dense calcified plaque were related to 12-year mortality in patients with low-to-intermediate complex CAD.
