An unusual presentation of herpes simplex encephalitis with negative PCR.
Article in BMJ case reports, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
A 74-year-old man presented with acute right-sided hemiparesis and epilepsia partialis continua in association with fever and confusion. Initial workup revealed possible cerebritis in the left medial frontal lobe without involvement of the temporal lobes. Cerebrospinal fluid (CSF) analysis revealed minimal lymphocytic pleocytosis but negative real-time herpes simplex virus (HSV) PCR. Acyclovir was discontinued on day 5 due to a negative infectious workup and clinical improvement. On day 9 his condition deteriorated and he was transferred to a higher level of acuity for advanced supportive care. Worsening encephalopathy and refractory status epilepticus ensued despite medical care. Repeat CSF analysis showed mild lymphocytic pleocytosis with negative real-time HSV PCR. Brain MRI revealed progression of cortical enhancement. Immunosuppressive therapy and plasma exchange were attempted without clinical response. On day 24, another lumbar puncture showed only mild lymphocytic pleocytosis. Brain MRI showed involvement of the right medial temporal lobe. Subsequently, acyclovir was resumed. The HSV-1 PCR result was positive on day 30. Unfortunately, the patient expired.
