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
We develop a statistical-mechanical model to calculate the structural properties of liquid water. The model is based on the generation of snowflake-like structures that serve as an approximation for the structure of liquid water. It is a two-dimensional model in which each water molecule has three interaction sites that can form three types of interactions, namely, hydrogen bonding, van der Waals contact, and no interaction. The structural model is based on the analytical water model─UD model used for the prediction of thermodynamic and dynamic properties; however, the UD model is not able to predict structural properties. Here, the UD model was adapted to match the properties of the rose water model used in the simulations. The thermodynamic and dynamic properties calculated with the adapted UD model and the simulations of the rose model are in good agreement. The new snowflake model was used to calculate the structural properties of water. With this model, we calculated the radial and angular distribution functions of the water molecules and compared them with the functions from the simulations of the rose water model. The snowflake model was very successful in reproducing the functions calculated from the simulations. In addition, the spatial distribution functions were calculated with the snowflake model. Altogether, the UD model and the snowflake model allow us to calculate the thermodynamic, dynamic, and structural properties of liquid water with comparable accuracy to the simulations, but only for a fraction of the calculation time.
