A rhombus-keyhole shaped circularly polarized dual-band implantable antenna with low SAR compliance.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
A compact dual-resonance implantable antenna with circular polarization (CP) has been proposed in this paper for bio telemetry applications. The antenna, with dimensions of 9 × 9 × 1.27 mm3, is designed using a reversed L-shaped patch, dual key-hole shaped structures and a central rhombus-shaped element. A shoring pin is employed to achieve dual-band resonance, while structural modification enables circular polarization. The proposed antenna resonates at 1.4 GHz (WMTS band) and 2.45 GHz (ISM band). The antenna is fabricated and measured using minced pork meat and saline solution. The measurement results show good agreement with the simulation results. Further, the SAR analysis and link budget analysis, prove that the antenna is suitable for real-time applications.
