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.
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
backgroundIntensive agricultural practices are increasing the generation of by-products and wastes, which require appropriate management strategies to prevent environmental pollution and recover valuable resources. Waste-to-energy technologies, such as anaerobic digestion, are gaining attention for integrating local feedstocks to produce biofuels and biofertilisers, contributing to closed nutrient cycles. In the Mediterranean region, olive pomace is very abundant, but its intrinsic characteristics hinder the production of biogas via anaerobic digestion. Concurrently, the direct application of untreated pig manure on agricultural land continues to pose significant environmental risks.
resultsThis study assessed the biomethane potential of olive pomace and pig manure, along with microbial population dynamics during the transition from mono- to co-digestion. Mono-digestion of olive pomace led to complete process inhibition, while co-digestion with pig manure increased methane yield more than fivefold (from 53 to 283 mL CH
conclusionsThese findings demonstrate that co-digestion can overcome the limitations of olive pomace mono-digestion, enabling the effective treatment of two challenging agro-industrial by-products. This approach aligns with circular bioeconomy principles and supports the decarbonisation of the olive oil and pig farming sectors, contributing to the energy transition. The presented approach serves as a baseline scenario, and further research should focus on recovering high-value bioproducts and advancing towards integrated biorefinery systems in rural areas.
