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
Splenic neoplastic and non-neoplastic lesions are frequently diagnosed in dogs and often exhibit overlapping clinical signs and gross morphological features, rendering histopathological examination essential for definitive diagnosis, therapeutic planning, and prognostic assessment. In Colombia, epidemiological data regarding these lesions remain limited, whereas international studies report considerable heterogeneity in the relative frequencies of neoplastic and non-neoplastic conditions. This study aimed to characterize the histopathological spectrum of splenic lesions in dogs and provide updated regional epidemiological data. A retrospective analysis was conducted on splenic specimens obtained from dogs subjected to total splenectomy between January 2019 and June 2024. All samples were processed and examined histopathologically at three veterinary pathology laboratories in Medellín, Colombia. Descriptive statistical analyses were performed considering year of submission, patient demographic data, morphological diagnosis, and concurrent histopathological findings. A total of 424 cases were evaluated, of which 282 (66.5%) corresponded to non-neoplastic lesions and 142 (33.5%) to neoplastic processes. The mean age of dogs with non-neoplastic lesions was 9.5 (< 1-16) years, whereas dogs with neoplastic lesions had a mean age of 10.2 (4-17) years. Splenitis was the most frequent non-neoplastic diagnosis, accounting for 54.6% of cases and demonstrating a higher prevalence than reported in prior literature. Among malignant splenic neoplasms, hemangiosarcoma was the predominant diagnosis, representing 69.2% of cases. This study demonstrates a high prevalence of non-neoplastic splenic lesions, particularly splenitis, and a frequent occurrence of multiple concurrent morphological diagnoses in non-neoplastic cases. These findings provide novel regional epidemiological data and contribute original information to international literature, underscoring the importance of histopathological splenic evaluation for accurate diagnosis and clinical decision-making.
