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
In the past decades, iron has been one of the intensively studied biodegradable metals due to its suitable mechanical properties, but it suffers from slow degradation in a physiological environment and low bioactivity. In this work, the beneficial properties of ceramic and polymer coatings were merged to enhance the corrosion properties and biological compatibility of Fe-based biomaterials. A new bilayer coating for Fe-based biomaterials that speeds up degradation while offering controlled, localized drug release to prevent infections was prepared. In addition, bioactive coatings with an incorporated antibiotic (gentamicin, Ge) were produced to introduce antibacterial properties into the prepared biomaterials and thus increase their bioactivity. The calcium phosphate (CaP) coating layer as well as a bioactive coating layer of CaP doped with gentamicin was electrochemically deposited onto an iron substrate. A layer of poly(ethylene glycol) was subsequently applied to the selection of prepared specimens to create a bilayer ceramic/polymer coating. Electrochemical and immersion corrosion tests revealed that the application of a bilayer coating allowed achieving the desired acceleration of degradation, while the application of only a ceramic coating led to a reduction in the corrosion rate. A slight increase in the corrosion rate was observed for samples with bioactive drug-containing coatings compared to samples with drug-free coatings. Higher viability of human fibroblastic cells cultured in the extracts of the tested samples was noted for samples with a bilayer coating compared to a ceramic coating. The addition of gentamicin in the bioactive coatings had no significant effect on the viability value. Antibacterial tests proved the antibacterial activity of samples with a gentamicin-loaded coating layer against
