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

In this study, biochars were produced from banana leaves (BB) and coffee husk (BC) for phenol adsorption. The biochars were characterized using Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, textural analysis, point of zero charge measurement, and determination of surface acidic and basic groups. For both biochars, a higher pyrolysis temperature led to losses of oxygenated groups as well as increases of graphitic structures and greater basic character. For biochars produced at 400 °C, phenol adsorption kinetics was best described by the pseudo-second-order model. Chemisorption involving π-π interactions was identified as the main adsorption mechanism. For biochars produced at 500 °C, a smaller pore size resulted in limited adsorption by intraparticle diffusion. The Freundlich model provided the best fit to the isotherm data due to the high surface heterogeneity. Moreover, the results also suggested the formation of multilayers or pore filling as adsorption mechanisms for the obtained biochars. The maximum adsorption capacity values (
