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
Epizootic haemorrhagic disease (EHD) is a notifiable disease to the World Organisation for Animal Health caused by Orbivirus ruminantium (EHDV), closely related to bluetongue virus (BTV) and transmitted by Culicoides spp. In autumn 2022, EHDV serotype 8 (EHDV-8) was detected for the first time in Spain and Europe, affecting domestic and wild ruminants. Red deer (Cervus elaphus) were the most affected wild species, with reports of neurological signs, severe respiratory distress and mortality. Nevertheless, the pathogenesis of EHDV-8 in this species remains poorly understood. This study aimed to evaluate the clinical and pathological impact of EHD in red deer, characterising clinical signs, main lesions, tissue distribution and target cells of EHDV. Clinical data were collected through a nationwide online survey and field outbreak studies, and histopathological and immunohistochemical analyses were performed on 16 confirmed EHDV-8 cases. Frequent clinical signs included neurological signs, ptyalism, lameness and dyspnoea. During the outbreak, average morbidity and mortality in captive red deer were 6.9% and 4.9%, respectively, with a case fatality rate of 70.3%, higher in males and almost exclusively in adults. Gross examination revealed extensive vascular and epithelial lesions with generalised congestion, focal to multifocal haemorrhages and marked pulmonary oedema, confirmed histologically with severe cellular damage. The most affected organs were the brain, lungs, liver, kidneys and spleen, showing interstitial oedema, vasculitis, mononuclear infiltration with necrosis, severe lymphoid depletion and gliosis with satellitosis in the brain. The EHDV antigen was primarily detected in macrophages, reticular cells, endothelial cells and epithelial cells. This study provides the first description of EHDV's clinical and pathological impact in red deer, confirming their high susceptibility to EHDV-8.
