1 · What the graph read from it

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.

2 · The registry

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

Hydrodynamic contrast recanalization (HDR)-a technique adapted from chronic total occlusion percutaneous coronary intervention in which small-volume microcatheter contrast injection creates a low-resistance pathway for wire crossing-can facilitate crossing of challenging culprit occlusions in acute myocardial infarction. We present 3 cases in which conventional wire escalation failed but HDR enabled successful first-attempt crossing, each representing a distinct occlusion acuity: acute thrombotic, subacute organized, and chronic total occlusion. Early use of HDR when crossing proves difficult may reduce crossing time, minimize dissection risk, and reduce thrombus embolization.
