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
abstractIatrogenic fungal infections are rare in immunocompetent patients. This report details a unique case of Aspergillus terreus and Aspergillus triticale infection following an epidural root block, highlighting the rare challenges in pathogen isolation, identification, and treatment, which complicate clinical management and patient outcomes. A male in his forties developed fever, headache, and weight loss postprocedure. Initial suspicion of meningitis was confirmed via lumbar puncture. Despite empirical antibiotics, corticosteroids, and antiedema measures, symptoms worsened. MRI revealed exudates on the pons and an infratentorial granuloma. Empirical antifungal therapy was initiated after cerebrospinal fluid galactomannan and beta-D-glucan assays tested positive, though fungal cultures were negative. Despite voriconazole treatment, the patient showed persistent symptoms with subtherapeutic drug levels. Dual therapy with voriconazole and amphotericin B failed. MRI of the lumbar spine revealed an epidural collection, prompting surgical intervention. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry performed on the purulent discharge from the laminectomy identified A . terreus and A . triticale . Subtherapeutic voriconazole levels, likely due to pharmacokinetics and drug interactions, necessitated switching to isavuconazole, leading to clinical improvement. A mixed fungal infection involving A . terreus and A . triticale is an uncommon occurrence in immunocompetent individuals. This case report delineates the diagnostic challenges encountered in isolating these fungal pathogens and the complexities associated with their management. By detailing our experience, this report aims to provide valuable insights for clinicians who may encounter similar rare infections, thereby aiding in timely diagnosis and optimized therapeutic strategies.
