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

backgroundThere is limited information available regarding the electrodiagnostic studies (EDX) features of hereditary sensory and autonomic neuropathies (HSANs) in dogs. HYPOTHESIS/

objectivesTo retrospectively describe the clinical and electrodiagnostic findings of dogs with suspected HSAN and to assess whether comprehensive EDX can assist in disease classification and prognostication. ANIMALS: Eleven client-owned dogs with early-onset distal sensory loss.

methodsMulticentric retrospective observational study (2008-2025). Inclusion criteria were distal sensory loss before 1 year of age, acral mutilations or analgesia of the toes, and complete EDX. Results of sensory nerve conduction studies (SNCS) and cord dorsum potential (CDP) were compared with normal values and with control dogs using an exact permutation test.

resultsTwo electroclinical patterns emerged. Pattern 1 included dogs with acral mutilation, preserved gait, and recordable but significantly reduced sensory nerve action potential (SNAP) amplitudes, sensory nerve conduction velocity (NCV), and CDP amplitudes (P < .05). Pattern 2 included dogs with tetraparesis and proprioceptive deficits; SNAPs and CDPs were absent in most nerves tested, and motor nerve conduction studies (MNCS) showed reduced compound muscle action potential amplitudes or reduced motor NCV, or both. Dogs in pattern 2 were euthanized within 12 months, whereas 5 of the 6 pattern 1 dogs showed stable or slowly progressive disease. CONCLUSIONS AND CLINICAL IMPORTANCE: Comprehensive EDX, including SNCS and CDP, identifies sensory and possible concomitant motor dysfunction in dogs with suspected HSAN and differentiates distinct electroclinical patterns associated with prognosis.
