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

purposeDespite increased interest in treating superficial femoral and popliteal arteries with endovascular technology, there is little data regarding comparative results of different treatment modalities in the popliteal artery. It was hypothesized that to improve clinical outcomes in this segment, drug-coating balloon (DCB) angioplasty would not be inferior to stent implantation.

methodsThe records of consecutive Chinese patients with popliteal lesions who were treated with DCB or stenting between June 2016 and February 2017 were retrospectively reviewed. The preoperative demographic, lesion characteristics and postoperative outcomes were compared and statistically analyzed. All patients were divided into different subgroups according to the degree of calcium or degree of ischemia.

resultsOne hundred two consecutive patients with popliteal lesions were treated with DCB or stenting and 95 (93.1%) completed a follow-up. Critical limb ischemia was present in 70.5% and occlusions were present in 61.1% of patients. DCB angioplasty was performed on 43 patients and angioplasty with primary stenting was performed on 52 patients. There was no difference in twelve-month primary patency (79.1% vs 82.7%; P = 0.687), secondary patency (95.3% vs 94.2%; P = 0.808) and amputation-free survival (93.0% vs 94.2%; P = 0.825) between the DCB group and stent groups. In patients with severe calcium, the twelve-month primary patency (61.1% vs. 79.2%; P = 0.239) and amputation-free survival (83.3% vs 87.5%; P = 0.739) did not differ between the DCB and stent groups.

conclusionsThis study demonstrates that DCB treatment in Chinese patients with popliteal atherosclerotic occlusive lesions can be associated with similar twelve-month patency and amputation-free survival compared to stenting, even in patients with severe calcification. LEVEL OF EVIDENCE: Level 3a, Non-randomized follow-up study.
