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 a novel rectangular aperture nano-antenna (RANA) design based on a hybrid plasmonic waveguide (HPW) configuration. The performance of the HPW is evaluated through theoretical analysis and compared with results from the Finite Integration Technique (FIT). The overall performance of the RANA is investigated at an operational frequency of 450 THz using both FIT and the Finite Element Method (FEM). The nano-antenna exhibits a directional radiation pattern, which is leveraged for refractive index biosensing. The biosensor's performance is characterized using a dry protein model with a refractive index ranging from 1.7 to 1.9. The sensing mechanism relies on monitoring shifts in the beam direction and variations in the power flow peak in response to changes in the refractive index of the dry protein as a material under test (MUT). The proposed biosensor achieves a sensitivity of 34.5 degrees per refractive index unit (RIU). The biosensor maintains strong performance over a 2 percent bandwidth centered at operational frequency, enhancing its detection robustness.
