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: Fractional flow reserve (FFR) has become the gold standard for diagnosing ischemia in angiographically intermediate epicardial coronary artery stenosis. This study investigated the clinical outcomes and predictors of revascularization deferral based on FFR. Methods: In this retrospective cohort study, we assessed 474 lesions (440 patients) where revascularization was deferred based on the FFR value. Minimum lumen diameter and %-diameter stenosis were measured. Calcification was graded as none, mild, moderate, or heavy. The synergy between percutaneous coronary intervention with taxus and cardiac surgery (SYNTAX) score I was also determined. The primary outcome was ischemia-driven target lesion revascularization (TLR) in deferred lesions within 3 years. Patients were also assigned into two groups based on FFR value. Results: The average age of the patients was 69.7±10.4 years. The average FFR value was 0.86±0.05. Stable angina pectoris was noted in 298 (67.7%) cases, and in-stent restenosis (ISR) was present in 28 (5.9%). The average SYNTAX score was 7.2±4.2. The 3-year ischemia-driven TLR was 18 lesions (3.8%). Cox proportional hazard model revealed that the SYNTAX score and ISR were independent predictors for TLR in deferred lesions [hazard ratio (HR) =1.10, 95% confidential interval (CI): 1.01-1.19, P=0.03; HR =6.33; 95% CI: 2.25-17.8, P<0.01, respectively]. The deferral group, with a low FFR value, tended to have higher TLR rates than other groups. Conclusions: Lesions with lower FFR values were associated with a higher incidence of ischemia-driven TLR than those with higher FFR values. SYNTAX score and ISR were predictors for ischemia-driven TLR at 3 years in the deferred lesions.
