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

ObjectivesFeline leukaemia virus (FeLV) infection - particularly the progressive course - continues to cause substantial morbidity and reduced survival in cats. Therapeutic options with proven antiviral effectiveness remain limited. This study aimed to evaluate the clinical and virological effects of the integrase inhibitor raltegravir in naturally infected, FeLV-progressive cats with FeLV-related conditions, clinical outcome, viraemia, proviral burden and survival.MethodsIn total, 14 client-owned cats with confirmed progressive FeLV infection and at least one FeLV-related condition were enrolled. Raltegravir was administered for 90 days, followed by a 90-day treatment-free observation period. Clinical evaluation and quantification of viral RNA and proviral DNA loads were performed at treatment initiation, day 45, day 90 and day 180. Cats continued to receive standard of care as clinically indicated. Survival data were recorded until study closure.ResultsAfter 45 days of treatment, plasma viral RNA load showed a non-significant mean reduction of 1.34 log
