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
Hierarchically porous graphitic aerogels (HGAs) are promising carbon materials owing to their low density, multilevel porosity, and interconnected frameworks, making them suitable for applications in energy storage, water purification, and environmental remediation. In this work, HGAs were synthesized from a range of protein-based precursors, including pasteurized egg white (PEW), α-lactalbumin, β-lactoglobulin, bovine serum albumin (BSA), and yogurt, through pyrolysis. The study investigates how precursor composition influences thermal decomposition and microstructural development. All precursors except yogurt formed interconnected sheet- and fiber-like frameworks due to the self-foaming effect during pyrolysis. Despite its high protein content, the yogurt precursor produced a rough porous morphology, likely due to the presence of fats and inorganic species that inhibit foaming action. Elemental analysis confirmed the presence of significant amounts of inorganic species, such as calcium and phosphorus, in the yogurt-derived samples. To examine the influence of nonprotein constituents, a control experiment was conducted using a casein-whey mixture, the primary protein component of yogurt. Pyrolysis of this mixture produced aerogels with interconnected sheet- and fiber-like morphologies, confirming that the additional nonprotein components in yogurt affect structure formation. Further Raman analysis indicates that increasing the pyrolysis temperature enhanced carbonization and graphitic ordering across all the samples. Overall, this work provides insight into developing HGAs from diverse protein precursors and shows how precursor composition influences microstructural development during protein pyrolysis, offering valuable guidance for the design of HGA-based composites and functional materials.
