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.

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
Forest composition and structural diversity play a key role in shaping habitat availability and biodiversity, particularly influencing the occurrence of saproxylic species associated with tree-related microhabitats (TreMs). TreMs and deadwood are essential features of forest ecosystems, offering critical habitats for saproxylic arthropods that contribute to decomposition, nutrient cycling, and overall forest resilience. Understanding the complex interactions between forest structures, TreMs, and arthropod communities is crucial for biodiversity conservation and sustainable forest management. This study examines how forest composition, deadwood characteristics, and TreMs influence saproxylic arthropods' diversity in the Black Forest, Germany. Using environmental DNA (eDNA) metabarcoding, we assessed arthropod communities across 135 forest plots with varying degrees of retention. Our findings reveal that specific TreMs, such as cavities, mosses, and insect galleries, were associated with arthropod richness patterns, particularly for Collembola, Hemiptera, and Arachnida. Canopy closure emerged as the most consistent predictor of arthropod richness, while tree-related microhabitats, lying deadwood volume, snag volume, and forest management intensity showed additional taxon-specific associations. These findings reveal that species richness is associated with multiple ecological factors, highlighting the complexity of forest ecosystems. They underscore the need for forest management strategies that preserve deadwood and TreMs, enhance structural heterogeneity, and consider broader indicators of forest naturalness to effectively support arthropod biodiversity.
