Decreased heart rate recovery may predict a high SYNTAX score in patients with stable coronary artery disease.

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
An impaired heart rate recovery (HRR) has been associated with increased risk of cardiovascular events, cardiovascular, and all-cause mortality. However, the diagnostic ability of HRR for the presence and severity of coronary artery disease (CAD) has not been clearly elucidated. Our aim was to investigate the relationship between HRR and the SYNTAX (SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery) score in patients with stable CAD (SCAD). A total of 406 patients with an abnormal treadmill exercise test and ≥50% coronary stenosis on coronary angiography were included. The HRR was calculated by subtracting the HR in the first minute of the recovery period from the maximum HR during exercise. The SYNTAX score ≥23 was accepted as high. Correlation of HRR with SYNTAX score and independent predictors of high SYNTAX score were determined. A high SYNTAX score was present in 172 (42%) patients. Mean HRR was lower in patients with a high SYNTAX score (9.8 ± 4.5 vs. 21.3 ± 9, p < 0.001). The SYNTAX score was negatively correlated with HRR (r: -0.580, p < 0.001). In multivariate logistic regression analysis, peripheral arterial disease (OR: 13.3; 95% CI: 3.120-34.520; p < 0.001), decreased HRR (OR: 0.780; 95% CI: 0.674-0.902; p = 0.001), peak systolic blood pressure (OR: 1.054; 95% CI: 1.023-1.087; p = 0.001), and peak HR (OR: 0.950; 95% CI: 0.923-0.977; p < 0.001) were found to be independent predictors of a high SYNTAX score. Our results showed that HRR is significantly correlated with the SYNTAX score, and a decreased HRR is an independent predictor of a high SYNTAX score in patients with SCAD.
