Time and time again: temporal processing demands implicate perceptual and gating deficits in the HIV-1 transgenic rat.

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
HIV-1-associated neurocognitive disorders (HAND) afflict up to 50 % of HIV-1+ individuals, despite the effectiveness of combination antiretroviral therapy (CART) in reducing the prevalence of more severe neurocognitive impairment. Alterations in brainstem auditory evoked potentials (BAEP), a measure of temporal processing, are one of the earliest neurological abnormalities of HIV-1-positive individuals. Prepulse inhibition (PPI) of the auditory startle response (ASR), a measure of sensorimotor gating, was studied in HIV-1 transgenic (Tg) rats, which express 7 of the 9 HIV-1 genes. Ovariectomized female Fischer HIV-1 Tg and control rats (ns = 41-42) were tested for PPI at three test periods, with at least 2 months separating each test period, using auditory and visual prepulses, an auditory startle stimulus, and interstimulus intervals (ISI) ranging from 0 to 4000 msec. Auditory and visual prepulse trial blocks were presented in counterbalanced order. For both auditory and visual prepulses, HIV-1 Tg animals exhibited a flatter ISI function, which did not sharpen with age, as it did in controls. Over time, auditory prepulses precipitated a temporal shift in peak inhibition in HIV-1 Tg animals relative to controls, whereas with visual prepulses, both groups displayed peak inhibition at the 40 msec ISI. A lack of perceptual sharpening with age and a relative insensitivity to the temporal dimension of sensorimotor gating are evident in the HIV-1 Tg rat prior to clinical signs of wasting. Deficits in sensorimotor gating may not only provide an early subtle diagnostic marker of HAND, but may also afford a key target for development of potential therapeutics.
