Unexpected Clinical and Laboratory Observations During and After 42-Day Versus 84-Day Treatment with Oral GS-441524 in Cats with Feline Infectious Peritonitis with Effusion.
Article in Viruses, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
The nucleoside analogue GS-441524 is a common treatment for cats with feline infectious peritonitis (FIP). In a previous study, 40 cats with FIP with effusion were treated with 15 mg/kg GS-441524 orally once daily for either 42 days or 84 days, and a 42-day treatment was as effective as the earlier recommended 84-day treatment. The aim of the present study was to describe unexpected clinical and laboratory observations occurring during and after treatment (within one year) in these cats and to compare them regarding the different treatment durations. Thirty-eight cats recovered rapidly during treatment, two cats had to be euthanized, and one cat was lost to follow-up. During treatment, 25 cats developed diarrhea. Lymphocytosis occurred in 26/40 cats during treatment, eosinophilia in 25/40 during treatment, increased alanine aminotransferase activity in 22/40, alkaline phosphatase activity in 7/40, and symmetric dimethylarginine levels in 25/40. These unexpected observations occurred equally in both treatment duration groups, but statistically significantly more cats developed lymphocytosis and eosinophilia when treated for 84 days. Although most of the unexpected observations during GS-441524 treatment improved or disappeared after treatment termination, these conditions have to be monitored, and treatment should not be given for longer than necessary.
