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
Rotational shifting cultivation (RSC) is a traditional agricultural practice in mountainous areas that uses fire to clear land after cutting vegetation for cultivation. However, few studies have assessed the effect of fire-deposited charcoal on the diversity and composition of soil microbial communities, and none have been conducted in Thailand. Therefore, this study was conducted 1 year after a fire in an abandoned 12-year RSC in Chiang Mai Province, northern Thailand. Charcoal samples were collected from the surface litter layer, while charcoal-soil mixtures were taken from the surface soil (0-2 cm). Soil samples from 2 to 7 cm captured the charcoal-soluble layer, and samples from 7 to 15 cm represented soil without charcoal incorporation. The results revealed that charcoal led to higher pH and electrical conductivity in the charcoal layer, with notable differences in soil texture across layers, including the highest sand and silt content in the charcoal-mixed soil layer (0-2 cm). Soil organic matter and total nitrogen were significantly higher in the charcoal-mixed layer compared to deeper layers, indicating improved nutrient retention due to charcoal presence. Enhanced microbial diversity was observed in the charcoal and charcoal-mixed soil layers, with Proteobacteria, Chloroflexi, and Planctomycetota dominating across all soil samples. The bacterial genus
