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.
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
backgroundTreating heavily calcified lesions is a challenge and is associated with high re-stenosis and target lesion revascularization (TLR). Before stent implantation, lesions must be adequately prepared using rotational atherectomy (RA), which has shown favorable results. The study aims to report our hospital's clinical outcomes when using rotational atherectomy on complex and heavily calcified coronary lesions with a single-burr strategy.
methodsWe retrospectively analyzed 58 patients who underwent percutaneous coronary interventions with RA at our center between December 2006 and April 2017. Data on immediate post-procedural events and major adverse cardiovascular events were collected during follow-up, including cardiovascular death, myocardial infarction, TLR, target vessel revascularization (TVR) and stroke.
resultsOf the 58 patients and 90 lesions treated over 10 years, 88 lesions (97.8%) used only one burr. The intervention procedure success rate was 100%. During a mean follow-up of 41.2 months, 6 patients experienced acute coronary syndrome, 12 required TLR, 2 needed TVR, and 6 died due to a cardiovascular event. We divided lesions into 5 categories. The prevalence of lesions and the burr size most commonly used were: category 1 (ostial lesion, 8.9%, 1.75 mm), category 2 (focal lesion, 20%, 1.75 mm), category 3 (intermediate lesion, 13.3%, 1.5 mm), category 4a (long, looser lesion, 26.7%, 1.5 mm), and category 4b (long, rigid lesion, 31.1%, 1.25 mm).
conclusionsRather than a routine step-by-step strategy for RA, this study shows convincing evidence supporting the use of this device to treat complex calcified coronary lesions using a single-burr strategy.
