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

Quantitative coronary analysis (QCA) of bifurcation lesions in the Nordic Bifurcation studies was performed using software dedicated to bifurcating vessels. By now, pre-PCI, post-PCI and 8-month follow-up angiograms of 957 patients have been analyzed in the first three Nordic Bifurcation studies. Large scale clinical studies with specific areas of interest require QCA software with high intra- and inter observer reproducibility, an efficient workflow, flexible features of analysis, a detailed output, and facilities for data export. Recently, a dedicated second generation 2D QCA bifurcation software became commercially available. We used this new software in the third Nordic Bifurcation study for efficient and tailored analysis. Despite widespread automation of the analysis process and experienced observers, an elaborate standard operating procedure is still essential for standardized high quality QCA analysis of bifurcation lesions.
