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
Introduction: Infrared radiation (IR) has a wide spectrum of both positive and harmful effects on the human body. Negative properties, manifested by increasing the level of reactive oxygen species (ROS), affect the skin ageing acceleration. Other adverse effect of infrared exposure is related to its ability to significantly penetrate deep into the skin, between its layers, up to blood vessels and other tissues and warm them up. Due to its harmful effects, protecting the skin against infrared radiation becomes an important issue. Aim: The aim of the research was verifying the usefulness of filters available on the market with protection against infrared radiation declared by the manufacturers, by examining their impact on the directional reflectance of the human skin. Methods: A group of 27 people was gathered, to obtain the results. Four products were applied on the participant's forearm skin, and then measurements of the directional reflectance of the skin were made at successive time points, using the 410-Solar reflectometer. The collected data was analyzed, and showed changes in reflectance under the influence of the applied protective products. Results: The products used in the study showed a statistically significant effect on the directional reflectance of the human skin in near infrared radiation range and little effectiveness for higher wavelengths. Discussion: The results indicate that the selected products show radiation protection against IR radiation only after several dozen minutes of application, which may suggest that they must penetrate deeper skin layers to be effective. Hemispheric directional reflectance turned out to be an effective method allows to assess the effectiveness of protective properties of cosmetics.
