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
Intravascular stenting in congenital heart disease (CHD) is a treatment modality that must account for patient somatic growth and future re-intervention. Stent expansion and intentional fracture can be performed safely and effectively. Limited understanding and data exist for drug-eluting coronary stents (DES). This study describes a serial dilation technique and characterizes dilation and fracture patterns of contemporary DES platforms. Using a standardized protocol designed to minimize foreshortening, five contemporary (DES) platforms were dilated with high pressure (HPB) and ultra-high-pressure balloons (UHPB) until fracture or non-fracture. Stent fracture type and characteristics of each stent tested were described. A total of 61 stents were tested: Resolute Onyx small (3.5-4.0 mm, n = 9, 15%), Resolute Onyx large (4.5-5.0 mm, n = 11, 18%), Synergy XD (3.5-4.0 mm, n = 13, 21%), Synergy Megatron (3.5-5.0 mm, n = 15, 25%), and Xience Skypoint (3.5-5.0 mm, n = 13, 21%). The majority of stents (57/61, 93%) were serially dilated to complete fracture, and a minority (4/61, 7%) of stents failed to fracture and foreshortened to a napkin ring configuration. Initial stent fracture occurred at a median balloon pressure of 15 atm (range 5-30 atm). Dilation of DES platforms using a standardized serial dilation protocol results in a high rate of intentional fracture with minimal foreshortening in ex vivo bench testing. These results may aid congenital interventional cardiologists using DES for CHD in the selection of stents and optimal techniques for intentional fracture in vivo.
