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

Conventional biogas stoves used for injera baking face major drawbacks, including uneven heat distribution, high fuel use, and inconsistent product quality that undermines cultural authenticity. This study designed and experimentally tested a novel biogas stove with a circular concentric burner paired with a thin clay-composite baking pan (Ø44 cm × 15 mm). Thermal tests showed the optimized pan reached its working temperature of 230 °C in just 20 min-cutting heating time by half compared to conventional pans, which required 40 min to reach 234 °C. A standardized batch process was established: each injera baked in 3 min, followed by a 2-minute idle recovery, ensuring stable temperature control within ± 5 °C. Using this cycle, a 5-injera batch was completed in 43 min, versus 63 min with conventional systems. Quality assessments confirmed authentic injera with consistent porosity (15-17 pores/in
