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
ConspectusThe separation and purification of liquid hydrocarbons are vital for producing various petrochemical feedstocks. However, the structural and chemical similarities among these hydrocarbons make conventional separation methods such as distillation and extraction both challenging and energy intensive. Adsorptive separation using porous solid adsorbents presents a promising and energy-efficient alternative. Among these, flexible metal-organic frameworks (FMOFs) as a subgroup of MOFs have emerged as an unparalleled class of porous materials for highly selective adsorption-based separation and purification of liquid hydrocarbons. Having intrinsically dynamic structures, FMOFs exhibit very different adsorption behaviors compared to rigid MOFs (RMOFs), those that do not involve structure transformations upon activation, and molecular adsorption.In recent years, we have focused on developing high-performance FMOFs with different dimensionalities, spanning from one-dimensional (1D) chains to two-dimensional (2D) layers and to three-dimensional (3D) networks. Their structural flexibility arises from either local rotation and vibration of organic linkers or global structural changes, enabling stimuli-responsive molecular adsorption. By leveraging their distinct temperature- and adsorbate-dependent adsorption behaviors, we have achieved highly efficient separation of numerous important liquid hydrocarbons through molecular sieving, the mechanism that offers the highest selectivity. The unique dynamic structures and adsorption properties allow FMOFs to have high adsorption capacity, exceptional selectivity, and fast kinetics simultaneously, overcoming the trade-offs typically encountered by conventional adsorbents including RMOFs.In this
