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
Background: A decrease in arterial elasticity may contribute to accelerated atherosclerosis, the sequelae of which are the most common causes of death in type 2 diabetes mellitus (T2DM) patients. The aim of this study was to assess ascending aorta (AA) and radial artery (RA) elasticity in T2DM patients via velocity vector imaging (VVI). Methods: We enrolled 50 patients with T2DM and 52 age- and sex-matched nondiabetic individuals as controls. All the participants underwent echocardiography and RA ultrasound examinations. AA elasticity parameters, i.e., ascending aortic mean longitudinal strain (ALS), ascending aortic global circumferential strain (ACS), ascending aortic fractional area change (FAC), and RA elasticity parameters, i.e., radial arterial mean longitudinal strain (RLS) and radial arterial global circumferential strain (RCS), were evaluated with VVI. The differences in arterial elasticity parameters between diabetic and non-diabetic patients were evaluated by a paired Results: We found that the T2DM group presented significantly lower ALS, ACS, FAC, RLS and RCS values than the control group did (all P<0.05). There were significant associations between all arterial elasticity parameters and glycosylated hemoglobin (HbA1c) and diabetes duration (ALS and HbA1c: r=-0.36, ALS and diabetes duration: r=-0.52, ACS and HbA1c: r=-0.32, ACS and diabetes duration: r=-0.38, FAC and HbA1c: r=-0.36, FAC and diabetes duration: r=-0.32, RLS and HbA1c: r=-0.39, RLS and diabetes duration: r=-0.46, RCS and HbA1c: r=-0.31, RCS and diabetes duration: r=-0.39, respectively; P<0.01). Additionally, the ALS was significantly negatively correlated with fasting plasma glucose (FPG) (r=-0.30, P<0.05). Conclusions: The elasticity of the AA and RA in T2DM patients was impaired. Decreased arterial elasticity was associated with poor blood glucose control and a longer duration of diabetes. Further studies are needed to assess the clinical value of VVI findings for predicting future cardiac events.
