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
backgroundIntravascular ultrasound (IVUS)-guided optimization of suboptimal fractional flow reserve (FFR) following percutaneous coronary intervention (PCI) results in a significant increase in both post-PCI FFR and minimal lumen and stent areas (MLA and MSA, respectively). However, the impact of clinical presentation with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) versus chronic coronary syndrome (CCS) on the efficacy of PCI optimization remains unknown.
methodsThis was a prespecified subgroup analysis of the FFR REACT trial comparing IVUS-guided PCI optimization versus no further treatment in 291 patients with a post-PCI FFR < 0.90. Post-PCI physiology and pre optimization IVUS findings were compared between patients presenting with NSTE-ACS versus CCS, as well as optimization strategy, final FFR and IVUS findings.
resultsOut of 291 patients, 130 (44.7%) presented with NSTE-ACS. Median post-PCI FFR was similar in patients with NSTE-ACS and CCS (0.85 for both, p = 0.55). Pre optimization IVUS findings did not differ significantly between both groups and subsequent optimization strategy was comparable (p = 0.71). In both NSTE-ACS and CCS, optimization resulted in a significant increase (p < 0.01 for all) of similar magnitude in median FFR (0.02 vs. 0.03, p = 0.80), MLA (0.37 vs. 0.50 mm
conclusionsIn patients undergoing FFR-directed IVUS-guided optimization, post-PCI FFR, pre optimization IVUS findings and optimization strategy did not differ significantly between patients presenting with either NSTE-ACS or CCS, with comparable improvements in FFR, MLA and MSA.
