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

objectivesThere is a lack of systematic data on cerebrospinal fluid (CSF) findings in the different clinical manifestations of tick-borne encephalitis (TBE) and according to the duration of neurological involvement. This study aims to evaluate and compare routine CSF parameters in TBE patients presenting with meningitis, meningoencephalitis, or meningoencephalomyelitis, and to assess temporal changes in CSF during the first 10 days after the onset of neurological symptoms.

methodsWe analysed 15 CSF parameters in 717 consecutive adult patients hospitalized for TBE at the Department of Infectious Diseases, University Medical Centre Ljubljana, Slovenia. Among these patients, 230 (32%) had meningitis, 446 (62%) meningoencephalitis, and 41 (6%) meningoencephalomyelitis.

resultsCSF findings differed significantly among the three clinical presentations. Leukocyte count, neutrophil proportion, protein levels, immunoglobulin concentrations (IgM, IgG, IgA), and intrathecal synthesis quotients were highest in meningoencephalomyelitis and lowest in meningitis. These differences remained largely significant after adjusting for confounding factors. CSF abnormalities were detectable from day one of neurological symptoms, peaked around days 4-5, and then stabilized or showed mild improvement. Neutrophils predominated during the first two days, followed by a predominance of lymphocytes and monocytes from day 3 onward. This pattern was consistent in meningitis and meningoencephalitis but less pronounced in meningoencephalomyelitis.

conclusionsClinical manifestations of TBE exhibit distinct CSF profiles. Abnormalities are most pronounced in meningoencephalomyelitis and least in meningitis. These alterations appear early, peak within the first days, and then stabilize or improve, although this pattern is less predictable in meningoencephalomyelitis.
