A Miniaturized UHF-Band Rectenna for Power Transmission to Deep-Body Implantable Devices.
Article in IEEE journal of translational engineering in health and medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
This paper presents the design, simulation, and fabrication of a 50 Ohm miniaturized rectenna for wireless energy harvesting for leadless pacemakers. The paper evaluates the performance of each section separately and also while cascaded. The system is designed to work at ultra-low RF input power. When the rectenna is placed 5 cm away from the body surface in simulations, the amount of received power is approximately -20 dBm. The proposed antenna is a miniature spiral PIFA with circular polarization at 673 MHz. The measured results, in and outside sheep's fat tissue, show that about 15 MHz bandwidth can be realized with [Formula: see text] below -10 dB and an axial ratio below 3 dB. Two types of rectifiers are fabricated and compared to choose the best one for such a system. Then, unlike most other researches which selected the doubler rectifier structure, this paper uses a single-diode rectifier structure at this power level. The rectenna can be encapsulated in a cylinder with a radius of 5 mm and a height of 3.2 mm. The efficiency of the rectenna reaches 40% at -20 dBm input power.
