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
Coronary flow capacity (CFC) integrates quantitative assessment of hyperemic myocardial blood flow and coronary flow reserve. We aimed to evaluate the effect of elective percutaneous coronary revascularization (PCI) on CFC using serial stress transthoracic Doppler echocardiography (STDE). Overall, 148 stable patients underwent STDE of the left anterior descending arteries (LAD), before and after elective PCI. Coronary flow velocity reserve (CFVR) was measured using basal and hyperemic diastolic peak velocity (hDPV). Vessels were classified into four CFC categories: severely, moderately, or mildly reduced CFC, and normal flow. Changes in hDPV and CFC status post-PCI, as well as predictors of hDPV increase, were assessed. Despite improvements in fractional flow reserve (FFR) in all cases, 31 cases (20.9%) showed a decrease in hDPV following PCI. Vessels with ischemic CFC, defined as moderately or severely reduced CFC, decreased from 46.6% (69/148) to 19.6% (29/148) post-PCI. Conversely, CFC worsened in 15.5% of patients. Multivariable analysis showed lower pre-PCI hDPV and ischemic CFC were independently predictive of higher-level (> 50%) hDPV increase after PCI. Approximately 20% of FFR-guided LAD PCI resulted in decreased hDPV. CFC deterioration was not uncommon despite FFR improvement. Preprocedural non-invasive STDE may help identify lesions that benefit from revascularization.
