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

introductionIntracoronary pressure measurements have improved assessment of angiographic intermediate coronary stenoses. Methodically, pressure equalization and actual measurements are frequently performed at different height levels, depending on the particular coronary territory analyzed. Considering a hypothetical influence of hydrostatic pressure and the supine position of the patient, differences in the results of intracoronary measurements between anterior and posterior vessels seem likely. The purpose of this study was to compare the results of intracoronary pressure measurements between anterior and posterior coronary territories.

methodsIntracoronary pressure measurements of 214 coronary stenoses in 158 patients were analyzed. Fractional flow reserve (FFR) was measured in all stenosis and instantaneous wave-free ratio (iFR) in 197 stenoses in 144 patients.

resultsBoth FFR (0.79 vs. 0.87, p < 0.001) and iFR values (0.86 vs. 0.94, p < 0.001) were significantly higher in posterior compared to anterior coronary vessels. Patients with only anterior or posterior lesions did not differ regarding clinical or lesion characteristics, in particular coronary stenosis severity (62.5 vs. 61.6 %, p = 0.27).

conclusionsResults of intracoronary measurements were systematically higher in the posterior coronary vessels when compared with anterior vessels. This phenomenon was independent of coronary stenosis severity or any clinical characteristics in our study population.
