A Method for Preparing Morphologically Preserved Wildlife Fecal Specimens for Long-Term Ecological Studies.

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
Wildlife feces are a valuable noninvasive resource in ecological and conservation research. However, traditional preservation methods are unable to maintain morphological integrity while simultaneously preserving the biological and chemical composition of fecal samples. This study introduces a novel method for the preparation of fecal specimens through a multistep infiltrated process using sodium carboxymethyl cellulose, sodium benzoate, clotrimazole, ethanol, pyrethroid emulsion, and polyvinylpyrrolidone solution. The entire procedure takes approximately 7 days to complete one batch of specimens. The specimens produced using this method exhibited high mechanical strength, ensuring durability and resistance to handling damage. Over an 18-month storage period, the preserved specimens retained their external morphology and showed no signs of mold or insect damage. DNA integrity was well maintained, with a 100% success rate in DNA extraction, and species identification based on preserved specimens was identical to that obtained from the corresponding pre-preservation feces. Furthermore, heavy metals such as chromium, arsenic, and lead were successfully detected in fecal samples from different species. By allowing long-term preservation of fecal samples, this method converts feces from a transient diagnostic tool into a durable resource for monitoring biodiversity. It can broaden the spatial and temporal applicability of fecal samples and strengthen their role in ecological research and biodiversity conservation.
