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
A novel bimetallic Fe-Mn-impregnated activated carbon (Fe: Mn: AC) composite was synthesized via the one-step dry pyrolysis method and is applied to tetracycline (TC) removal from aqueous solution. Characterization results revealed a mesoporous structure with various functional groups on the Fe: Mn: AC adsorbent. The impacts of solution pH, adsorption time (kinetics), and initial TC concentration on equilibrium in batch adsorption were studied. The highest TC removal efficiency using Fe: Mn: AC occurred at a pH of 6. The kinetic analysis using various models revealed that the data best fit the Elovich model, highlighting the significance of external diffusion (film diffusion) during the adsorption process. The equilibrium data aligned well with the Langmuir isotherm, which predicted a maximum adsorption capacity of 463.040 mg/g for TC adsorption at 25 °C. The primary mechanisms of adsorption included Hydrogen bonding, surface complexation with metal functional groups (M-π), Lewis acid-base interactions, π-π interactions, and pore filling. Continuous mode experiments in five cycles confirm the high adsorption capacity of the Fe: Mn: AC adsorbent for effectively removing pharmaceutical contaminants from aqueous media (27.5% reduction in adsorption ability).
