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
Constant pressure pumps are an invaluable yet underutilized resource for microfluidic flow systems. In particular, constant pressure pumps are able to stabilize the fluid pressure in systems where the viscosity may change due to chemical reactions or the flow rate may vary due to deformations of the channels. The constant pressure pump presented here is designed on the premise of creating and maintaining a pressure differential between the laboratory and a pressure reservoir. This pressure reservoir is then used to drive the input fluid at the specified gauge pressure. The pump design presented here is perfect for primarily undergraduate institutions and other laboratories with modest research budgets as it can be built for under US$100 and construction is within the scope of an advanced undergraduate. The pump consists of an Arduino-compatible microcontroller, Adafruit electronic components, low-voltage air pump, Nalgene water bottle, and various fluid components. A complete parts list is included in the appendix. Comparable commercial pumps have a retail price in excess of US$5000. Multiple pump designs were constructed and tested with the ability to hold a constant pressure of up to 14 psig (97 kPa-gauge) with a maximum flow rate of 65 [Formula: see text]L/s for water.
