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
Precise stent positioning during percutaneous coronary intervention (PCI) for coronary ostial lesions is technically important but often challenging. During ostial stenting, the guiding catheter (GC) frequently requires slight disengagement from the coronary ostium, which may result in catheter instability caused by cardiac motion and respiratory fluctuation. Such instability can interfere with reliable intravascular ultrasound (IVUS)-guided landmark recognition and controlled stent deployment. Although accurate stent placement at the coronary ostium is clinically important, few practical strategies specifically address GC instability during IVUS-guided ostial PCI. We describe a modified jailed balloon anchor technique (JBAT) used to stabilize the GC during IVUS-guided ostial stenting. In this technique, a small balloon positioned in a side branch is gently inflated at low pressure to function as an anchor, thereby mechanically coupling the GC and coronary artery and reducing relative displacement during cardiac motion. This maneuver facilitated stable IVUS landmark recognition and controlled stent positioning in a case with substantial catheter movement.
