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
Background: This study delves into the epidemiology and pathomorphologic characteristics of peste des petits ruminants (PPR) in western Algeria, a viral disease that constantly threatens small animals in Africa, the Middle East, and Asia. Aim: The purpose of this investigation was to evaluate the epidemiology of PPR in western Algeria and to understand the pathomorphological lesions in naturally infected small ruminants. Methods: An online survey conducted via google forms and shared with veterinarians in the wilaya of Tiaret, provided insights into the prevalence and clinical manifestations of PPR.A comprehensive examination of organs was conducted and representative tissue samples from the lungs, trachea, thymus, spleen, liver, kidney, heart, tongue, stomach, different parts of the small and large intestine, and mesenteric lymph nodes were collected and the specimen was fixed in a 10% neutral buffer formalin solution. Results: Among 2,200 small ruminants managed by expert veterinarians, 192 small ruminants exhibited clinical signs compatible with PPR, and 79 dead animals. Among the 31 sick young small ruminants, eight were confirmed to be infected with the PPR virus. Necropsies of affected animals revealed significant gross lesions in organs such as the lungs, intestines, spleen, and lymph nodes. Histopathological analysis further illuminated the severity of lesions, including interstitial pneumonia, syncytial cell formation, and severe gastroenteritis. Conclusion: The study's comprehensive approach, encompassing epidemiological data, necropsy findings, and histopathological insights, contributes valuable knowledge for understanding and managing PPR outbreaks.The pathological lesions observed in this study exhibited consistency with those previously documented in experimental studies, thereby providing support for the diagnosis based on clinical signs and disease history.
