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
This study presents the development of a composite electrode material for lithium-sulphur (Li-S) batteries, combining MOF-74 with carbon black and sulphur. The MOF-74 structures, incorporating Ni(II), Mg(II), and Fe(II) metal ions, were synthesized via a solvothermal method and used to encapsulate sulphur. The microporous nature of MOF-74 facilitates the physical confinement and storage of sulphur, potentially enhancing the performance of Li-S batteries. The investigation focuses on how different central metal ions in MOF-74 influence the performance of sulphur-based electrodes. Among the metal ions studied, Fe(II) and Mg(II) were selected for their low toxicity, cost-effectiveness, and availability, while Ni(II) was included for its high catalytic properties. The materials were thoroughly characterized using infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy, powder X-ray diffraction, elemental analysis and X-ray photoelectron spectroscopy. The thermal stability and textural properties of the materials were assessed, showing that MOF-74(Mg) exhibited the highest stability, followed by MOF-74(Ni) and MOF-74(Fe). Nitrogen adsorption/desorption measurements indicated that the specific surface area and pore volume varied with activation temperature, impacting the material's performance. Among the tested materials, MOF-74(Ni) exhibited the strongest interaction with sulfur, as confirmed by XPS analysis. Electrochemical tests revealed that the S/MOF-74(Ni) electrode demonstrated superior stability and capacity retention with a minimal capacity fading rate of 0.001% per cycle over 200 cycles, achieving a reversible capacity of 465 mAh g
