An All-in-One Microfluidic Device for Blood Plasma Separation and Fluorescence Detection of Cocaine in Whole Blood.

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
Blood drug testing can provide real-time data to assess the recent consumption of illicit drugs. Microfluidic devices have great promise in rapid finger-prick blood tests at point-of-care settings. However, the fabrication of an integrated microfluidic device for whole blood testing remains a challenge because the separation performance is sensitive to modification in downstream product microchambers. In this work, a hydrodynamic force-based blood plasma separation unit has been developed to regulate the blood plasma separation efficiency and yield after it is integrated with the waste outlet, the connection, and detection zones in a microfluidic device. After the plasma is separated from blood by this microfluidic separation unit, it is driven to an aptamer-based detection zone downstream. As a result, this integrated fluorescence microfluidic device can directly detect the cocaine metabolite, benzoylecgonine (BEC), in a drop of whole blood sample with readout by a hand-held fluorescence reader, achieving a limit of detection (LOD) of 0.62 μg/mL. This integrated all-in-one microfluidic device can serve as a general detection platform for the measurement of various analytes in finger-prick whole blood samples.
