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

Oil palm trunks (OPT) represent an underutilized agricultural byproduct that poses significant environmental challenges. The effectiveness of OPT as feedstock for biochar production will be depends on carbonization conditions, yet the relationship between process parameters and biochar properties remains insufficiently explored. This study investigates the potential of converting OPT into micropores bioadsorbent through controlled carbonization. Biochar was produced at temperatures of 300, 400, and 500 °C, with residence times of 2, 3, and 4 h, and subsequently characterized for its physicochemical properties and adsorption capacity. The results indicate that biochar produced at 300 °C for 2 h exhibited the highest surface area (10.24 m
