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

Herpes simplex encephalitis is a devastating disease. In the early 1980s our group conducted a nationwide clinical trial of acyclovir versus vidarabine in patients with herpes simplex encephalitis in whom intrathecal herpes simplex virus (HSV) antibodies were assayed. The purpose of this study was to investigate if antibody levels and viral load correlate with outcome in herpes simplex encephalitis. We have analysed the prognostic value of HSV antibody levels in serum and cerebrospinal fluid (CSF) at the start of antiviral treatment in the 53 included patients. Frozen samples from a subset of patients were analysed with quantitative polymerase chain reaction (PCR) to assess the prognostic value of the viral load in CSF. IgG-levels in CSF at presentation were significantly higher in vidarabine-treated patients with a favourable outcome than in those treated with vidarabine but with an unfavourable outcome. The intrathecal viral load at presentation showed no correlation with outcome. However, the duration of positive HSV-PCR in CSF was longer in vidarabine-treated than in acyclovir-treated patients. These findings indicate that the B-cell response is important in the pathogenetic process of herpes simplex encephalitis. However, neither antibody levels nor viral load at presentation are useful as prognostic markers for the individual patient in this study.
