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
Clear-cutting disrupts forest structure, alters litter accumulation, and impairs nutrient cycling in dry forest ecosystems. This study evaluated the effects of clear-cutting on litter and nutrient stocks in hyperxerophilous Caatinga in northeastern Brazil in areas under different regeneration stages (0, 6, 9, 12, 25, 50 years, and a reference site) in northeastern Brazil. Stocks and concentrations of total carbon (TC), total nitrogen (TN), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sulfur (S) were measured. Statistical analyses included Generalized Linear Models (GLM) with gamma distribution, MANOVA for multivariate comparisons, Principal Component Analysis (PCA) to identify structural gradients, and hierarchical cluster analysis to classify lignocellulosic profiles. Results showed that clear-cutting substantially reduces litter and nutrient stocks, particularly N and P, and increases the TC/TN ratios-especially in the litter-negatively affecting litter accumulation. After 50 years, regeneration had not restored pre-disturbance levels. Litter biomass was functionally associated with soil P, Ca, and S. PCA revealed two main gradients: one axis of recalcitrance (related to FDA, cellulose, and NDF) and one axis of lignin-cellulose complexity, which discriminated materials with different decomposition potentials. Multivariate analyses revealed gradients linked to recalcitrance and litter decomposition potential. These findings indicate that the TC/TN ratio and nutrient availability regulate litter persistence and ecosystem resilience. Enrichment planting with species having lower TC/TN ratios, green manuring, and biodiversity restoration are recommended to improve litter quality, accelerate nutrient cycling, and promote recovery of ecosystem functions in drylands.
