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

objectiveDiabetics are at increased risk after stent implantation and potentially sensitive to the type of stent and dual anti-platelet therapy (DAPT). The randomized, double-blind LEADERS FREE trial compared 2432 patients at high bleeding risk (HBR) receiving either a polymer-free BA9-coated stent (DCS) or a bare metal stent (BMS) with 1 month of DAPT, and showed superior safety and efficacy of the DCS at 2 years. We report outcomes at 2 years of the pre-specified diabetic subgroup. METHODS AND

resultsThe diabetic sub-group comprised 805 (33.1%) patients; 262 (10.8%) were insulin-dependent (IDDM). Compared to non-diabetics, diabetics were younger and had more risk factors and multi-vessel disease. They suffered higher rates of death (15.6 vs. 12.2%, p = 0.01), cardiac death (8.3 vs. 5.9%, p = 0.02), myocardial infarction (MI) (11.1 vs. 7.8%, p = 0.009) and definite/probable stent thrombosis (3.1 vs. 1.7%, p = 0.01), but rates of clinically-indicated TLR (9.1 vs. 9.5%, p = 0.93) and BARC 3-5 bleeding (10.2 vs. 8.4%, p = 0.20) were comparable. Compared to diabetic patients treated with a BMS, diabetic DCS recipients required less clinically driven TLR (6.3 vs. 12.2%, p = 0.006). The primary safety endpoint (cardiac death, MI, definite/probable stent thrombosis) occurred numerically less frequently in the DCS group (14.9 vs. 19.7%, p = 0.10), and was significantly lower in IDDM patients (13.8 vs. 25.4%, p = 0.03). BARC 3-5 was similar for patients treated with DCS (9.9%) and BMS (10.5%, p = 0.84).

conclusionsIn diabetic HBR patients, DCS significantly reduced re-intervention rates over BMS, and showed a strong trend towards a safety benefit at 2 years. CLINICAL
