A 10 m High-precision Canopy Height Product for Nanping City, Fujian Province, China.
Article in Scientific data, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
As a key ecological barrier and core carbon sink area in Southern China, Nanping City presents significant challenges for high-accuracy forest canopy height mapping due to its unique vegetation structure and complex topography. The current products for canopy height couldn't meet the requirements for accurate carbon stock estimation. This study calibrated the biases in GEDI data by proposing an innovative Bias Calibration Model and combined with multi-source data including Sentinel-1, 2, UAV LiDAR, and topographic data, produced 10-meter canopy height products for 2022 and 2023 for Nanping City using a random forest model. The generated data products achieved R² = 0.62 for both 2022 and 2023 when validated against independent UAV data, with RMSE = 2.88 m and 3.09 m for 2022 and 2023 respectively, accurately characterizing the vertical structural attributes of the forest This study provides a reliable data foundation for the estimation of subsequent forest biomass and carbon stock.
