Case Report: Re-Emergence of Cochliomyia hominivorax in Costa Rica: Report of a Human Myiasis Case 23 Years after Elimination.
Article in The American journal of tropical medicine and hygiene, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
The New World screwworm, Cochliomyia hominivorax Coquerel (Diptera: Calliphoridae), was officially eliminated from Costa Rica in 2000, but it was reintroduced in 2023. A myiasis by C. hominivorax in a 71-year-old man with a 4-month history of foot hyperkeratosis and interdigital ulcers is reported. The myiasis was detected before sampling for bacterial culture. Approximately 160 first- and second-instar larvae were recovered and identified as C. hominivorax. Morphological identification was based mainly on characteristics of the cephalopharyngeal skeleton, spiracles, and pigmented dorsal tracheal trunks. Sequencing of a cytochrome c oxidase subunit I gene fragment confirmed the identity. The ulcers healed after extraction of the larvae and ciprofloxacin treatment of a concurrent Staphylococcus aureus and Pseudomonas aeruginosa infection. Given the reintroduction of C. hominivorax in Costa Rica and the risk of northward expansion, this report highlights its impact on public health and calls for awareness among clinicians and healthcare practitioners.
