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

As an alternative to environmentally unfriendly disposal of spent activated carbon (SAC) from point-of-use water treatment systems, this study harnessed SAC as a co-substrate in anaerobic digestion for biogas production. The study investigated how SAC pre-treatment methods, namely, washing, particle size (milled vs. granular), and dosing levels (2.5%, 5%, and 7.5%), influenced biogas yield, methane content, and retention time using cow dung as the primary substrate. SAC from chlorinated water purification (KC) and the other from borehole water treatment (KZ) were investigated in this study. KZ had a higher %TOC (5.4955%) compared to < LOD for KC, indicating it retained more usable carbon for microbial activity. However, KC had a higher surface area (110.58 m
