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
Feline diffuse iris melanoma (FDIM) is a common ocular neoplasm, typically affecting older cats, characterized by progressive hyperpigmentation and potential malignancy. This study evaluated the diagnostic value of iris biopsies in distinguishing FDIM from benign iris melanosis. Seventeen cases with suspected FDIM were analyzed through ex vivo iris biopsies and corresponding enucleated globes. Histological evaluation by 8 pathologists revealed an average concordance of 81.6% between biopsy and globe diagnoses. The reliability of biopsy samples was influenced by tissue quality, with 12/136 slides deemed non-diagnostic due to artifacts or insufficient tissue. While biopsy retrieval offers a less invasive alternative to enucleation, its effectiveness is limited by technical factors, including tissue handling and sampling techniques. The results suggest that iris biopsies can be valuable for diagnosing advanced FDIM but require skilled execution. Further studies should explore early-stage FDIM and melanosis to better assess the diagnostic potential of biopsies across various disease stages.
