Spinal Deformities in Wild Reptiles: A Systematic Review and Meta-Analysis.
Review in Biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Spinal deformities-such as kyphosis, scoliosis, and lordosis-are observed across all major vertebrate groups. Reports in wild reptiles are increasing but are mainly published in natural history notes as curiosities, with little exploration of their aetiology, pathology, prevalence, or consideration of potential ecological, evolutionary, and life history implications. Addressing this gap, I compiled the most comprehensive database to date by reviewing the peer-reviewed and grey literature and collecting unpublished records via standardised social media inquiries. I identified 690 observations from 146 sources, covering 109 reptile species in 24 families across 37 countries. Spinal deformities appear across all major reptile clades, though Testudines are over-represented (78.6% of all observations and 42.2% of all species). A phylogenetic meta-analysis of 54 effect sizes from 37 species yielded a global prevalence estimate of 0.21%, with no significant effects of phylogeny, habitat use, or habitat type detected, possibly due to dataset limitations. However, kyphosis was more common in (semi)aquatic Testudines, whereas scoliosis was more frequent in terrestrial squamates. Although deformities may impair key life history traits, supporting evidence remains scarce. The findings highlight the understudied nature of spinal deformities in wild reptiles and underscore the need for standardised, ecologically informed reporting to better understand their causes and consequences.
