1 · What the graph read from it

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.

2 · The registry

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

Phenolic pollution poses a significant environmental issue due to its toxicity and persistence in aquatic ecosystems. This study investigates an innovative approach utilizing immobilized Salinivibrio kushneri within alginate and water hyacinth-derived biochar microspheres for the removal of phenol from aqueous solutions. Bacterial strains with high phenol-degrading capacity were isolated, and the best-performing strain was identified by 16 S rDNA sequencing (GenBank accession no. PQ836117). Two biosorbents were evaluated: Bacteria-Alginate Microspheres (BAMs) and Bacteria-Loaded Biochar-Alginate Microspheres (BLBAMs). The BLBAMs outperformed BAMs, achieving phenol removal rates over 87%. This maximum efficiency was achieved under optimal conditions of pH 7, 30 h contact time, and a phenol concentration of 51.76 mg/L. Kinetic and isotherm modeling indicated that the adsorption process was driven by chemisorption and followed the Langmuir model, with a monolayer adsorption capacity of 53.19 mg/g. The pseudo-second-order model (R
