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
objectiveHypercholesterolemia (increased blood cholesterol level) is considered a major risk factor for developing atherosclerotic diseases. As such, alerting individuals on hypercholesterolemic conditions is a crucial component in averting onset of atherosclerosis and its outcome-cardiovascular diseases. While common diagnostic tools such as cholesterol and lipoproteins determination are widely employed for hypercholesterolemia screening, their effectiveness has been questioned since they do not shed light on critical physiological factors like lipid oxidation and inflammation levels, which constitute prominent determinants for development of atherosclerotic diseases. The objective of this study is to develop a simple assay for identifying hypercholesterolemia, and assessing the impact of therapeutic treatments.
methodsWe developed a diagnostic assay based upon color transformations of polydiacetylene, a unique conjugated polymer, upon interactions with blood plasma obtained from healthy individuals, hypercholesterolemic patients, hypercholesterolemic patients treated with statin, and hypercholesterolemic patients treated with statin together with pomegranate extracts. The color transformations of the polymer were monitored through desktop color scanning combined with colorimetric image analysis.
resultsWe show that the colorimetric assay was able to distinguish among plasma. Bio-analytical characterization reveals that the distinct colorimetric responses likely arise from interactions with plasma lipoproteins. Importantly, the colorimetric changes are not simply correlated with the relative abundance of cholesterol (or other lipids) in the plasma of hypercholesterolemic or healthy patients, but also reflect the presence of oxidized and inflamed species.
conclusionsThis paper introduces a simple color assay for detection of hypercholesterolemia and monitoring the effect of therapies directed at mitigating this physiological condition. The colorimetric system might constitute a novel platform for assessing patient vulnerability towards the development of atherosclerosis.
