Peripheral blood soluble elastin and elastase as auxiliary diagnostic indicators for coronary artery ectasia
Article in Turkish journal of medical sciences, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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/aim: Damage to elastin fibres in coronary media might lead to coronary artery ectasia (CAE). This study evaluated whether CAE can be distinguished by detecting circulating soluble elastin (s-elastin), which is a degradation product of elastin fibres, and elastase, which is the main enzyme of elastin fibres. Materials and methods: Fifty-eight patients with CAE, 58 with coronary heart disease (CHD) and 61 with relatively normal coronary arteries, were included. Circulating s-elastin and elastase were measured, and receiver operating characteristic curves were used to demonstrate their respective optimal cut-off values for predicting CAE. Results: The concentrations of s-elastin and elastase were higher in the CAE group than in the CHD and relatively-normal-coronary groups. Their cut-off values for screening of CAE were 13.148 ng/mL and 25.549 ng/mL, respectively; for sensitivity of CAE were 0.690 and 0.773, respectively; and for specificity of CAE were 0.862 and 0.571, respectively. A combination of s-elastin and elastase in series (one of the two higher than its cut-off value) had a better sensitivity for screening for CAE, whereas their combination in parallel (both higher than their cut-off values) had a better specificity. Conclusion: Circulating s-elastin and elastase are promising biomarkers for assisting in CAE diagnosis.
