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

Although antiretroviral (ARV) therapy has reduced the incidence of severe dementia associated with HIV infection, there has been a rise in milder neurocognitive complaints. Data from HIV patients taking ARVs have shown measurable neurocognitive improvements during drug cessation, suggesting a neurotoxic role of the therapy itself. Mechanisms underlying potential ARV neurotoxicity have not been thoroughly investigated, however pathologic oxidative stress and mitochondrial dysfunction have been suspected. Using DIV 16 primary rat cortical neuron culture, we tested eight ARVs from the three most commonly prescribed ARV classes: nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs/NtRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), and protease inhibitors (PIs) for effects on neuron viability and morphology after 24 h of drug exposure. Of the tested NRTIs, only stavudine at nearly 100 times the target plasma concentration affected neuron viability with no appreciable change in morphology. Dideoxyinosine induced dendritic simplification at 100 times target plasma concentrations, but did not adversely affect viability. The sole NtRTI, tenofovir, induced dendritic simplification at approximately 3-4 times target plasma concentration, but did not affect viability. Of the tested PIs, only amprenavir decreased neuron viability at nearly 100 times the target plasma concentration. The non-nucleoside reverse transcriptase inhibitor, efavirenz, consistently reduced viability (at 50 µM) and induced dendritic simplification (at 20 µM) nearest the target plasma concentration. Probing mitochondrial energetics of DIV16 cortical neurons after exposure to 20 µM efavirenz showed rapid diminution of mitochondrial-dependent oxygen consumption. Further, 20 µM efavirenz decreased excitability in ex vivo slice culture whereas 2 µM had no effect.
