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
Street art murals are increasingly recognized as valuable contemporary artworks, often attaining significant artistic, historical, and social importance. As these murals become integral parts of cultural heritage, finding efficient strategies for their conservation is crucial. However, their typical large surface areas, heterogeneous materials, and high variability in exposure to environmental and pollution factors pose significant challenges in establishing appropriate analytical strategies to obtain the necessary information. This study proposes a multiscale and multitechnique noninvasive approach to investigate and monitor street art murals in situ. By combining portable point techniques-such as external reflection Fourier transform infrared spectroscopy, Raman spectroscopy, visible, near infrared, and short-wave infrared reflectance spectroscopy, and X-ray fluorescence spectroscopy-with visible and near infrared hyperspectral imaging, the mural's composition across a square meter surface could be analyzed. Additionally, multispectral imaging mounted on a drone provided a global reconstruction and characterization of the overall mural. This method was complemented by microdestructive laboratory analyses of selected samples, using pyrolysis gas chromatography-mass spectrometry and liquid chromatography coupled with diode array detector and tandem mass spectrometry, to further investigate selected samples and support noninvasive results. The approach was applied to the iconic mural "Musica Popolare" (2017) by Orticanoodles in Milan, Italy, revealing detailed information about its pigments, binders, fillers, and degradation. The findings demonstrate the potential of this integrated methodology for the effective material identification, conservation assessment, and short-and long-term monitoring of urban heritage.
