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
Thin interbedded coal seams exhibit characteristics of numerous layers, minimal thickness, and a clustered distribution. Horizontal well cross-seam fracturing technology represents an effective approach for coalbed methane exploration and development. However, the adaptability of construction parameters for longitudinal cross-seam fracturing in thin interbedded coal seams remains a critical factor constraining the seamless integration of horizontal wells with coal seam clusters and hindering efficient gas production. This study experimentally analyzed the mechanical characteristics and mineral content of coal and rock based on mechanical properties, mineral composition, and pore structure. A fully three-dimensional, structured grid geological model of the longitudinal multithin interbedded formation was constructed using the GOHFER platform. Crack propagation simulations were conducted, and the parameters for longitudinal cross-bedding fracturing operations were optimized through a five-factor, four-level orthogonal experimental design. Research findings indicate that the compressive strength of the roof and floor strata in coal seams 10# and 12# exceeds that of the coal mixture, exhibiting higher brittleness. The crack pressure for coal seams 10# and 12# ranges between 13.22 and 13.35 MPa. The roof and floor strata contain a high proportion of clay minerals, reaching 62.4-67.7%. When perforation points are located within the roof strata of the lower coal seam, vertical cracks can effectively communicate between the two coal seams. However, when perforation points are situated within the lower coal seam itself, cracks encounter significant difficulty penetrating upward through the intercalated layer, thereby limiting their ability to communicate with the overlying coal seam. Taking into account both the longitudinal layer-penetrating capability of cracks and the convenience of construction organization, the recommended combination of construction parameters is flow rate 14 m
