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

objectivesLyme neuroborreliosis (LNB) presents with a broad range of symptoms and its incidence is increasing in Finland. This study examines clinical differences in LNB between adults and children (< 16 years), emphasizing head and neck symptoms, the prognostic value of laboratory tests, the findings in brain MRI, and the impact of glucocorticoids on facial palsy (FP) recovery.

methodsA retrospective analysis of LNB cases at Turku University Hospital (2011–2018) confirmed by intrathecal antibody production against Borrelia was conducted. With regard to cerebrospinal fluid pleocytosis, LNB was further classified as definite or possible. Patient characteristics were compared using appropriate statistical tests.

resultsIn total 159 adult and 25 child LNB patients were found. The most common symptom in adults was radiculitis (37% vs. 8%, p = 0.03), while in children, it was FP (76% vs. 46%, p = 0.0052). In children, the absence of FP was linked to delayed diagnosis (5.5 ± 9.1 weeks vs. 0.97 ± 0.92 weeks p = 0.043). Of the pediatric LNB patients, 68% were seropositive for antibodies against Borrelia based on serum samples. Cranial nerve enhancement was observed in 26% of brain MRIs in the study cohort. No link between CSF findings or corticosteroid treatment and persisting FP was found.

conclusionsIn adults, the most common manifestation related to LNB was radiculitis, whereas in children it was FP. One third of the pediatric patients were seronegative for antibodies against Borrelia, emphasizing the importance of CSF analysis in the diagnosis of LNB. Corticosteroids did not affect the recovery from FP and CSF findings had no prognostic value on recovery from FP.
