Factors affecting diagnostic difficulties in aseptic meningitis: a retrospective observational study.
Observational study in Diagnosis (Berlin, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesThe purpose of this study was to determine the actual diagnostic status of aseptic meningitis and consider the factors that cause difficulties in its diagnosis.
methodsThis study retrospectively reviewed the medical records of aseptic meningitis treated at our hospital from 2013 to 2022 and compared biometric data to distinguish between timely diagnose and difficult diagnose cases.
resultsThis retrospective observational study included 127 patients aged 18 years or older. 66 (52.0 %) were female, with a median age of 35.9±15.9 years. The main symptoms were headache (122, 96.1 %), general malaise (110, 86.6 %), vomiting (79, 62.2 %). The 127 patients were classified into two groups: A timely diagnosis group diagnosed within 6 days of symptom onset, and a difficult diagnosis group diagnosed within 7 days or longer. There were significant differences between the two groups in the proportion of patients with a history of antimicrobial treatment and fever above 38 °C, and in the positive rates of neck stiffness and jolt accentuation of headache (JAH). The total number of hospitals involved in the process of diagnosis was significantly higher in the difficult diagnosis group and the length of inpatient stay was significantly longer. Multivariate analysis revealed significant differences in neck stiffness, JAH, and prior antibacterial therapy.
conclusionsAtypical cases, such as neck stiffness and JAH negativity, may make the diagnosis difficult. Clinicians should be aware of this atypical presentation of aseptic meningitis.
