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
backgroundChestnuts are keratinized skin structures found on equine limbs, but their characteristics in donkeys remain poorly understood. This study aimed to characterize chestnut morphology and histology in Dezhou donkeys and examine correlations with phenotypic traits.
methodsA cross-sectional study was conducted on 347 Dezhou donkeys (0.3-15 years, 79-419 kg). Chestnut dimensions were measured using precision calipers, and correlations were analyzed with age, body weight, limb measurements, and thoracolumbar vertebral counts. Histological analysis compared chestnut tissue with adjacent normal skin using standard H&E staining protocols.
resultsDonkeys exclusively possessed chestnuts on forelimbs, predominantly showing regular geometric configurations. Histologically, chestnut tissue exhibited marked hyperkeratosis (>30 cellular layers vs. 4-6 in normal skin), widespread melanocyte distribution throughout the epidermis, and complete absence of cutaneous appendages. In group A, strong positive correlations were observed between chestnut width and age (r = +0.527,
conclusionsChestnuts in Dezhou donkeys represent specialized integumentary structures with unique histological features and strong correlations with somatic development. These findings support their potential utility as biometric markers for individual identification and indicate coordinated developmental regulation with overall growth patterns.
