Isolated pulmonary valve endocarditis in a 7-year-old Nigerian girl: a case report.
Article in Journal of medical case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundRight-sided infective endocarditis is a rare clinical entity, with isolated pulmonary valve infective endocarditis being extremely uncommon. Infective endocarditis carries a high mortality rate and significant complications, making early identification and prompt management crucial in improving outcomes. This case highlights an unusual presentation of right-sided infective endocarditis isolated to the pulmonic valve in a pediatric patient with no apparent preexisting heart disease. CASE PRESENTATION: A 7-year-old girl of Yoruba ethnicity presented with septicemic illness, congestive heart failure, and no evidence of congenital cardiac lesion, underlying valvular disease, or identifiable predisposing factors. She had underweight malnutrition, cachexia, and severe respiratory distress. Echocardiography, which was delayed due to resource limitations, ultimately revealed isolated myxomatous vegetation on the pulmonary valve, dilated right cardiac chambers, and pulmonary hypertension. Blood cultures grew Pseudomonas aeruginosa. The patient was managed with antimicrobial agents, an anticardiac failure regimen, antiplatelets, and supportive therapy. Management was complicated by financial constraints, which delayed optimal intervention.
conclusionAlthough isolated pulmonary valve infective endocarditis is rare in the pediatric population, particularly in the absence of identifiable heart disease, a high index of suspicion is essential. Early diagnosis via echocardiography and prompt, adequate treatment are crucial for favorable outcomes. Awareness of potential diagnostic delays and financial barriers can aid in optimizing timely intervention and improving prognosis.
