A low-cost electric micromanipulator and its application to single-cell electroporation.

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
Micromanipulation techniques are essential in studies of cell function, both for single cells and for cell collectives. Various types of micromanipulators are now commercially available. Hydraulic micromanipulators have the advantage of analogue operation, allowing the user to move the glass microneedle in direct response to their own hand movements. However, they require regular maintenance to maintain their performance. On the other hand, some electric micromanipulators can operate in minute steps of several hundred nanometers, but they are expensive. This paper describes our assembly of a low-cost electric micromanipulator. The device consists of three commercially available stages, three linear DC motors to drive them, and a lab-made control circuit. Using this device, we were able to direct a glass microneedle to cut an MDCK cell sheet. We also manipulated an aspiration pipette to aspirate a portion of a
