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.

2 · The registry

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

Pressure fluctuations, which invariably occur in microfluidic systems, usually result in the unstable fluid delivery in microfluidic channels. In this work, a novel microfluidic gas damper is proposed and applied for providing stable fluid-driving pressures. Then, a pressure-driven flow setup is constructed to investigate the gas damping characteristics of our damper. Since the pressure-driven flow setup functions as a resistor-capacitor low-pass filter, the damper significantly decreases the amplitude of the input pressures via self-regulating its pneumatic resistance. In addition, the gas volume and pressure frequency are found to have direct effects on the pressure fluctuations. The practical application of the gas damper is examined through a portable pressure-driven system, which consists of an air blower, a gas damper, and a centrifuge tube. By periodically pressing the air blower, precise flow rates with low throughput (∼9.64
