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.

Abstract

backgroundChronic total coronary occlusions (CTOs) represent a subgroup of coronary lesions with a low procedural success and high recurrence rate. However, there is evidence for a prognostic benefit of revascularizing a CTO.

objectiveThis study assessed the prevalence of CTOs among patients with stable angina pectoris and its impact on therapeutic strategies.

methodsBetween 2001 and 2003, a survey was conducted in 64 sites to analyze the outcome of the first diagnostic angiography in patients presenting with stable angina pectoris (STAR registry). The clinical characteristics, initial angiographic findings, therapeutic strategy and outcome within the first year were analyzed.

resultsA total of 2,002 patients were entered into the registry. One-third had at least one CTO. At 1 year, the mortality in patients with a CTO was significantly higher than in those without a CTO (5.5 vs. 3.1%; P = 0.009). This excess mortality was related to a higher prevalence of confounding factors in patients with a CTO such as diabetes and more severe LV dysfunction. Patients with a CTO were more likely to undergo surgery or being treated medically, whereas patients without a CTO were more likely to undergo PCI. If a CTO was treated by PCI the periprocedural and long-term outcome was similar to those with PCI for a non-occlusive lesion. However, periprocedural MACE was higher for patients treated for a non-occlusive lesion without first treating the CTO.

conclusionsThe prevalence of CTOs in patients with stable angina pectoris is high, and it influences the clinical outcome within the first year. The therapeutic strategy is influenced towards a rather conservative approach and lower rates of interventional therapy.
