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

Orthoflaviviruses are etiological agents of neurological diseases in equines. Horses are susceptible to equine Tick-borne encephalitis virus (TBEV), Usutu virus (USUV), and West Nile virus (WNV), although mostly WNV has been associated with clinical disease. The aim of the present study was to estimate the prevalence of TBEV, USUV and WNV in 289 healthy horses from nine provinces of Algeria. This study was conducted between March 2021 and December 2023. Sera that tested positive, doubtful, or negative close to the doubtful threshold in the Orthoflavivirus-ELISA were further tested by the virus neutralization test (VNT), using TBEV, USUV, and WNV strains. The prevalence of Orthoflaviviruses antibodies by ELISA was 23.18% (67/289) compared with 16.95% (49/289) and 0.69% (2/289) detected by WNV and USUV VNT, respectively. TBEV antibodies were not detected in any samples. WNV seroprevalence varied with age, breed, climatic zones and altitude of the horses' locations. This is the first screening of horse sera for TBEV in Algeria. This study indicates that WNV and USUV have circulated/are circulating in the horse population in three Algerian climatic zones, unlike TBEV, which does not seem to be present.
