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
In Japan, the current indication for intravascular lithotripsy (IVL) in percutaneous coronary intervention (PCI) is based on the intravascular ultrasound (IVUS) or optical coherence tomography (OCT) calcium score of ≥ 3. We aimed to investigate a new IVUS-based criterion equivalent to OCT calcium scores. We retrospectively analyzed 110 cases with moderate or severe calcification on angiography, along with analyzable pre-PCI OCT or optical frequency domain imaging and simultaneous pre-/post-PCI IVUS. For the transition from the OCT calcium score to the IVUS-based approach, we used the cutoff value of receiver operating characteristic analyses. OCT-derived maximum calcium angle > 180° was replaced by the IVUS-derived maximum calcium angle > 225°, and the OCT-derived calcium length > 5.0 mm was replaced by the IVUS-derived calcium angle > 180° in > 3 mm length. The IVUS-derived maximum calcium angle > 225° was equivalent to the OCT calcium score ≥ 3 (positive predictive value of 0.972), and meeting both IVUS surrogate markers was equivalent to that of 4 (positive predictive value of 0.982). Patients with the IVUS-derived maximum calcium angle > 225° or meeting both IVUS surrogate markers had a higher incidence of stent underexpansion at the maximum calcification site (10.9% versus 0%, p = 0.044; or 12.8% versus 1.8%, p = 0.046, respectively). An IVUS-derived maximum calcium angle > 225° or meeting both the IVUS-derived maximum calcium angle > 225° and the IVUS-derived calcium angle > 180° in > 3 mm length could provide a useful alternative to OCT calcium score of ≥ 3 or 4 and could predict stent underexpansion at the maximum calcification site.
