Atypical presentation of Lyme disease in a returning traveler: a case report.
Article in Tropical diseases, travel medicine and vaccines, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Lyme disease, caused by Borrelia burgdorferi and transmitted by Ixodes ticks, is rare in South America and is often misdiagnosed in returning travelers. We report the case of a 19-year-old Peruvian male who presented with pruritic erythematous maculopapular lesions and abdominal pain after travel to Maryland, United State of America. His atypical cutaneous findings, including a crusted lesion with ill-defined borders and a maculopapular rash, were initially misinterpreted as bacterial cellulitis, resulting in multiple unsuccessful courses of antibiotics. Further evaluation, guided by his travel history, led to the diagnosis of Lyme disease through serological testing and histopathology. Treatment with doxycycline achieved complete resolution. This case illustrates the diagnostic challenges posed by atypical presentations of Lyme disease in nonendemic regions. Greater awareness among clinicians in South America is essential to recognize imported cases, facilitate early diagnosis, and prevent complications associated with delayed treatment.
