Transcriptome data from the interdigital webs of the Chinese Soft-shell Turtle (Pelodiscus sinensis).
Article in Scientific data, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The interdigital webs of aquatic tetrapods are a key structure evolved for adaptation, which are formed by inhibiting interdigital cell death (ICD). Diverse interdigital morphologies have independently evolved among species, and the regulatory mechanisms responsible for their development are still not fully understood. The Chinese soft-shell turtle (Pelodiscus sinensis) serves as a good research model that exhibits transitional traits from webless to fully webbed. In this study, we collected eight samples of interdigital webs from the fore- and hindlimbs of turtles at embryonic stage 19 (TK19) for RNA sequencing (RNA-seq) analysis. We identified 608 differentially expressed genes (DEGs). Whole-mount in situ hybridization (WISH) and real-time quantitative PCR (RT-qPCR) of representative genes confirmed the accuracy of the transcriptomic results. These findings not only provide new perspectives and data to support comparative studies of adaptive convergent evolution in aquatic animals but also enhance our understanding of the mechanisms underlying tetrapod limb morphogenesis. Furthermore, these results provide potential molecular targets for research on the plasticity of programmed cell death or senescence.
