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

backgroundEasily obtainable biomarkers for non-infectious, inflammatory central nervous system (CNS) disorders in dogs are lacking. HYPOTHESIS/

objectivesDogs with non-infectious inflammatory CNS disorders might have specific neural autoantibodies in serum or cerebrospinal fluid (CSF), or both, discoverable by commercially available indirect immunofluorescence (IIF) assays. ANIMALS: Dogs (n = 23) with non-infectious inflammatory CNS disorders, including meningoencephalomyelitis of unknown origin, were recruited from the University Hospital for Companion Animals (Copenhagen, Denmark).

methodsUsing an exploratory, prospective study design, serum and CSF from dogs were investigated for specific neural autoantibodies with cell- and tissue-based IIF assays used to identify neural autoantibodies in humans.

resultsAstrocytic autoantibodies against glial fibrillary acidic protein were present in 2 dogs, neuronal targeted autoantibodies against N-methyl-D-aspartate receptors (NMDAR) in 2 dogs, and tripartite motif-containing protein 46 in 1 dog. Additionally, autoantibodies toward myelin were suspected in 6 dogs and myelin-oligodendrocyte glycoprotein in 4 dogs. Autoantibodies against a neuronal surface structure were suspected in 1 dog but could not be further specified. CONCLUSIONS AND CLINICAL IMPORTANCE: This study confirmed the presence of neural autoantibodies in several dogs with non-infectious inflammatory CNS disorders. The importance of both tissue- and cell-based assays (CBA) is emphasized by the fact that all specific autoantibodies apart from those targeting NMDAR were detected by tissue-based assays and then confirmed on cell-based assays (CBA).
