Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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 study investigates a compact acoustic metasurface of periodic parallel Helmholtz resonators with a resonator defect located in the middle of the structure for gas-sensing applications. Introducing defects into the common resonators' array creates localized resonant modes that affect the gas properties, improving sensitivity. The resonance frequency shift occurs due to the filling gas samples inside the defective structure. Using the finite element method, numerical simulations show that the defective Helmholtz resonator modifies the pressure distribution and reduces the band gap. The study shows that high sensitivity can be achieved by optimizing the number of periodic cells associated with defect modes. Hence, Helmholtz resonator arrays are good candidates for hazardous gas detection. The structure is analysed considering different parameters. The results indicate improved sensitivity with an increasing number of Helmholtz resonators, highlighting the potential use of these systems in environmental monitoring and safety.
