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

backgroundSuccessful chronic total occlusion (CTO) revascularization has been associated with prognostic benefits. Whether the extent of coronary artery disease interferes with these benefits has not been investigated yet.

aimsWe sought to compare the survival after percutaneous coronary intervention (PCI) for CTO between patients with multi- (MVD) and single-vessel disease (SVD).

methodsA total of 2002 consecutive patients undergoing CTO PCI between 01/2005 and 12/2013 were identified and stratified according to the presence/absence of MVD. The primary endpoint was all-cause mortality. Median follow-up was 2.6 (interquartile range 1.1-3.1) years.

resultsA total of 1634 (81.6%) patients had MVD. Procedural success rates were 81.5 and 89.7% in the MVD and SVD groups (p < 0.001). All-cause mortality during entire follow-up was higher in MVD as compared to SVD patients (13.5 versus 5.7%, p < 0.001), and differences were attenuated after multivariable adjustment for baseline characteristics [adjusted hazard ratio (HR) 1.51, 95% CI 0.98-2.33, p = 0.06]. The effect of successful CTO PCI on all-cause mortality was consistent among patients with MVD [11.0 versus 24.5%; adjusted HR 0.60, 95% CI 0.45-0.80, p < 0.001] and SVD [5.2 versus 10.5%; adjusted HR 0.74, 95% CI 0.24-2.26, p = 0.59, P

conclusionsSuccessful recanalization of a CTO is a strong independent predictor for reduced long-term mortality. Due a higher baseline risk, the absolute benefit in patients with MVD is substantially larger than in patients with SVD.
