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
Protein adsorption on solid surfaces provides either beneficial or adverse outcomes, depending on the application. Therefore, the desire to predict, control, and regulate protein adsorption on different surfaces is a major concern in the field of biomaterials. The most widely used surface modification approach to prevent or limit protein adsorption is based on the use of poly (ethylene oxide) (PEO). On the other hand, the amount of protein adsorbed on poly(2-(dimethylamine)ethyl methacrylate) (PDMAEMA) coatings can be regulated by the pH and ionic strength of the medium. In this work, ultra-thin PEO/PDMAEMA coatings were designed from solutions with different ratios of PEO to PDMAEMA, and different molar masses of PEO, to reversibly adsorb and desorb human serum albumin (HSA), human fibrinogen (Fb), lysozyme (Lys), and avidine (Av), four very different proteins in terms of size, shape, and isoelectric points. X-ray photoelectron spectroscopy (XPS), quartz crystal microbalance (QCM), and atomic force microscopy (AFM) were used to characterize the mixed polymer coatings, revealing the presence of both polymers in the layers, in variable proportions according to the chosen parameters.
