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

We present a MEMS intravascular implant designed for wireless cardiac pacing. This micropacer implant is meticulously engineered to refine the fabrication process, provide adequate cardiac stimulation, and maintain a compact form factor. An innovative roll-to-capsule technique allows a one-piece micropacer, which includes a parylene circuit board for discrete components, stimulating ring electrodes, and an encapsulation layer. Our design employs a low-frequency inductive power transfer using primary and secondary coils in a back-to-back configuration, ensuring consistent power delivery for pacing even if the coils become minutely misaligned. The finalized device measures 1.8 mm in diameter and 12 mm in length, allowing for catheter-delivered insertion into the cardiac vein. Benchtop tests confirmed the device's capability to deliver a 3.5V DC output voltage with a coil separation of one inch.
