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
Sparganosis is a parasitic zoonosis caused by plerocercoid larvae of Spirometra species, commonly transmitted through ingestion of infected copepods or raw intermediate hosts. A 51-year-old man presented with a palpable mass in his right thigh. Surgical excision revealed a worm-like structure. Histopathological and serologic findings suggested sparganosis, and PCR amplification of the cox1 gene from paraffin-embedded tissue showed 99% sequence identity with Spirometra erinaceieuropaei (GenBank accession No. KJ599680.1). Praziquantel (75 mg/kg/day for 3 days) was administered, and the patient showed no evidence of recurrence during follow-up. Eosinophilia was not observed; however, positive sparganum antibodies supported the diagnosis. This case demonstrates that molecular identification using mitochondrial genes can be a valuable diagnostic tool, especially when morphological features are limited. Furthermore, it highlights the zoonotic potential of S. erinaceieuropaei and underscores the importance of food safety, hygiene education, and continuous epidemiological surveillance to prevent human sparganosis in endemic regions.
