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

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causes an immune-mediated neurological syndrome, which persists long after infection. Mechanisms for SARS-CoV-2-associated neurological complications are multifactorial, with an increased risk of drug abuse such as methamphetamine (meth). SARS-CoV-2 infection and its viral proteins play pivotal roles in coronavirus disease 2019 (COVID-19)-associated neuroinflammation, which can lead to long COVID. We hypothesize that meth augments activation of the microglial NOD-, leucine-rich repeat, and pyrin domain-containing protein 3 (NLRP3) inflammasome by the SARS-CoV-2 nucleocapsid (N) protein, resulting in neuroinflammation. To test this hypothesis, we investigated the effect of N-protein and meth on NLRP3 inflammasome activation in primary rat microglial cultures using enzyme-linked immunosorbent assay (ELISA), Reverse Transcription quantitative Polymerase Chain reaction (RT-qPCR), western blot (WB), and immunofluorescence assay (IFA). Our results showed that meth augmented N-protein-induced microglial activation, as evidenced by increased ionized calcium-binding adapter 1 (Iba-1) expression. The addition of meth to the microglial cultures treated with N-protein increased proinflammatory cytokine production. Meth augmentation of N-protein-induced neuroinflammation was further supported by increased inducible nitric oxide synthase (iNOS)-mediated nitric oxide (NO) production. The effects of meth on N-protein-associated inflammatory responses were significantly attenuated by MCC950, a specific NLRP3 inhibitor. Moreover, meth-associated NLRP3 activation was either blocked by the opioid sigma1-receptor (σ1
