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

Soil degradation is a major constraint to agricultural productivity in Ethiopia, particularly in highland regions where erosion, acidity, and nutrient depletion are widespread. Although biochar has shown promise in restoring soil health, its effectiveness depends heavily on feedstock type and production conditions. Rumex abyssinicus, a culturally significant and abundant Ethiopian plant, has been studied for activated carbon but not for biochar synthesis or soil rehabilitation using stem biomass. This study addresses that gap by optimizing biochar production from Rumex. abyssinicus stems using response surface methodology (RSM), and evaluating its impact on degraded soil. Pyrolysis parameters: temperature, time, heating rate, and particle size, were optimized to maximize yield, achieving 31.98% under ideal conditions. The resulting biochar exhibited high fixed carbon (78.8%), large surface area (455.1 m
