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
unlabelledObesity in childhood increases the risk for early adult cardiovascular disease. However, the underlying mechanism is not fully known. The aims of this study were to measure levels of prothrombotic factors and examine their possible association with obesity and insulin resistance in obese children and adolescents. A total of 313 obese children and adolescents were recruited. In a cross-sectional design, we measured anthropometric parameters, plasminogen activator inhibitor-1-antigen (PAI-1-Ag), von Willebrand factor-antigen (vWF-Ag), fibrinogen (FB), lipids, fasting glucose, and insulin (FI) levels. Insulin resistance was estimated using the homeostasis model assessment for insulin resistance (HOMA-IR) index. Boys presented significantly higher PAI-1-Ag levels than girls (82.6 vs. 71.3 ng/ml, p = 0.01). Higher levels of PAI-1-Ag (96.8 vs. 69 ng/ml, p < 0.001), vWF-Ag (123.5 vs. 107.6%, p = 0.004) but not FB (353.1 vs. 337.6 mg/dl, p = 0.137) were found in insulin-resistant (IR) participants after adjusted for age, gender, and pubertal stage. IR patients were at 2.98 (CI: 1.084-8.193) and 4.86 (CI: 1.119-15.606) times greater risk for high PAI-1-Ag and vWF-Ag levels, respectively. All three prothrombotic factors were positively correlated with body mass index (BMI) and FI levels (p < 0.05), but only PAI-1-Ag and vWF-Ag were significantly correlated with HOMA-IR index (p ≤ 0.001). After adjustment for confounding factors, both BMI and HOMA-IR indices remained significantly associated with PAI-1-Ag (r₂ = 0.225, p < 0.001) and vWF-Ag levels (r₂ =0.077, p = 0.003).
conclusionThis study shows that obesity in youngsters, when accompanied with insulin resistance, is associated with at least threefold increased risk for elevated levels of prothrombotic factors, contributing to the early development of atherothrombosis. This impaired prothrombotic state may partially explain the increased risk for developing cardiovascular disease later in adulthood.
