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
Schistosomiasis remains a major global health concern, affecting approximately 260 million people, with 440 million experiencing morbidity and over 800 million at risk of infection. According to the World Health Organization (WHO), it ranks as the second most socioeconomically impactful infectious disease and the third most significant parasitic disease in terms of public health. This study aimed to improve immunodiagnostic tools for Schistosoma mansoni in resource-limited settings by developing monoclonal antibodies (MoAbs) using locally available materials. MoAbs were produced using hybridoma technology and assessed for specificity to soluble worm antigen preparation (SWAP) through ELISA. Immuno-phosphatase and immuno-peroxidase staining were employed to localize target antigens across various life cycle stages and assess cross-reactivity with related species. Four distinct MoAbs demonstrated strong phosphatase and peroxidase activity in the gut and tegumental tubercles of S. mansoni adult worms, with extreme (4+) phosphatase staining. The dorsal tubercles and oral/ventral suckers showed strong (3+) peroxidase staining. S. mansoni schistosomula showed positive staining in the oral sucker and penetration glands, while cercariae showed no reactivity. Cross-reactivity with S. haematobium was minimal, showing only weak (1+) peroxidase staining in gut and tegumental structures, as well as the intact worm's tegumental tubercles and suckers. In conclusion, the MoAbs developed exhibited high specificity for S. mansoni with limited cross-reactivity to S. haematobium, supporting their potential utility in locally produced, sensitive immunodiagnostic tools to strengthen schistosomiasis control and elimination efforts in endemic regions.
