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
Objective: To investigate the feasibility of quantitative fluorescence angiography with intra-arterial dye injection (Q-iaFA) for intraoperative guidance during revascularization procedures in patients with chronic limb-threatening ischemia (CLTI). Methods: In this observational cohort study, 14 patients with CLTI undergoing endovascular intervention were included. Q-iaFA was performed directly before and after revascularization. The parameters time to peak (TTP) and normalized peak slope (PS Results: Q-iaFA was successful without complications in all patients. Revascularization impact was classified as strong in 8 (57%), moderate in 5 (36%), and as absent in 1 (7%) patients. In the strong impact group, a significant decrease in TTP and increase in PS Conclusions: Q-iaFA is a feasible technique to evaluate peripheral tissue perfusion during vascular interventions. The extracted perfusion parameters are directly affected by revascularization of arterial lesions in patients with CLTI. This finding suggests that Q-iaFA may be useful to guide intraoperative decision making. Work is required to refine quantification strategies and relate Q-iaFA parameters to clinical outcomes.
