1 · What the graph read from it

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.

2 · The registry

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

objectiveTo explore pathological findings on magnetic resonance imaging (MRI) and their diagnostic implications in early-stage neuroborreliosis (NB).

methodAdult patients from the Danish neuroinfections cohort (DASGIB, 2015-2019) with confirmed NB, symptom duration < 6 months, and MRI performed within 14 days of diagnosis were included. MRIs were retrospectively reinterpreted by an unblinded neuroradiologist.

resultsIn 116 patients, 123 MRIs were performed (99 brain, 44 spine, 46 with contrast). White matter lesions (WML) were common, but non-specific and associated with increasing age (p < 0.001). Six patients showed WML not typical for small vessel disease. Acute infarctions occurred in four patients. Encephalitis was clinically diagnosed in five patients; one showed brainstem FLAIR hyperintensities. In 45 contrast-enhanced brain scans, leptomeningeal enhancement was identified in 6 (13%) and cranial nerve enhancement in 29 (64%). There was poor correlation between facial palsy and enhancement. Spinal cord lesions (1.6-14 cm) were identified in 10 of 44 scans (23%) without symptoms of transverse myelitis. Among 13 contrast-enhanced spine scans, 8 showed leptomeningeal enhancement (61%), and 8 showed nerve root enhancement (61%). Most enhancements did not match symptoms.

conclusionPathological findings were found in 35 of 46 patients with contrast-enhanced MRIs. Key findings included cranial nerve, spinal nerve root, and leptomeningeal enhancement-often without clinical correlation. Spinal cord lesions were relatively frequent; cerebral infarction was rare. While key findings can support the diagnosis, their absence does not exclude NB.
