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

Japanese encephalitis (JE) virus (JEV) is a leading cause of neurological infection in the Asia-Pacific region with devastating socioeconomic consequences. We aimed to develop a target product profile (TPP) for JE diagnostics in endemic areas in the context of other flaviviruses, to better define improvements needed for patient management and public health. Thematic experts were identified from a scoping review, World Health Organization and Encephalitis International databases, as well as author networks. Initial interviews were performed with selected experts to inform a draft TPP document and start a Delphi process, aiming for consensus of ≥75% on each characteristic. A one-day meeting facilitated in-depth discussion, with breakout groups and electronic voting to develop the final TPP document. In total, 460 participants were invited. Five interviews enabled drafting a TPP. Two iterative surveys were completed by 44 respondents, including clinicians, scientists, and public health experts from 15 countries. A hybrid meeting was attended by 42 participants. Seven priority characteristics were discussed, and consensus was achieved for six; no clear consensus was reached for the preferred test sensitivity and specificity, with 73% agreement. Discussion points and areas of expert consensus were consolidated into a roadmap for development and implementation to guide future work. A diverse group of health professionals agreed that improved diagnostics for JE are needed, and that a priority is a test for patient management that detects JE alongside other relevant flavivirus infections. There was a mandate for a rapid diagnostic test (RDT), and it was suggested that this could be implemented in a two-tiered diagnostic algorithm. The final TPP is presented in the paper; this aims to help define the updates needed to better support patient management and public health interventions, to provide a strategic reference document to drive innovation and improve clarity for JE diagnostic test developers.
