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

backgroundCoronary calcification is a major determinant of stent underexpansion and subsequent adverse events. This study aimed to evaluate the acute- and long-term outcomes of rotational atherectomy (RA) followed by cutting balloon (CB) versus plain balloon before drug-eluting stent implantation for calcified coronary lesions.

methodsFrom June April 2013 to March 2016, a total of 127 patients with moderately or severely calcified coronary lesions were treated with RA. Patients were divided into two groups according to the balloon type after RA: RA+CB group (n = 75) and RA+plain balloon group (n = 52). Minimal lumen diameter and acute lumen gain were analyzed by quantitative coronary angiography. In-hospital and long-term (>1 year) outcomes were recorded. Multivariate Cox regression analysis was performed to determine the independent predictors of in-stent restenosis.

resultsThe mean age of the patients was 65.5 years, and 76.4% were men. Total lesion length and minimal lumen diameter at baseline were similar in the two groups. After RA and balloon dilation, the lumen diameter was significantly larger in the RA+CB group than in the RA+plain balloon group (1.57 ± 0.46 mm vs. 1.10 ± 0.40 mm, t = 4.123, P < 0.001). The final lumen diameter was also larger in the RA+CB group compared to that in the RA group (2.81 ± 0.41 mm vs. 2.60 ± 0.25 mm, t = 2.111, P = 0.039). Moreover, patients receiving RA and CB tended to have larger final lumen gain (2.15 ± 0.48 mm vs. 1.95 ± 0.47 mm, t = 1.542, P = 0.132). Multivariate Cox regression analysis indicated that the strategy of RA+CB was a significant protective factor against long-term (>1 year) in-stent restenosis (hazard ratio: 0.136, 95% confidence interval: 0.020-0.936, P = 0.043).

conclusionsIn patients with moderately or severely calcified lesions, a strategy of RA followed by CB before stent implantation can increase lumen diameter and acute lumen gain. This strategy is safe with lower risk of long-term in-stent restenosis.
