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

SARS-CoV-2 causes an acute respiratory tract infection that resolves in most people in less than a month. Yet some people with severely weakened immune systems fail to clear the virus, leading to persistent infections with high viral titres in the respiratory tract. In a subset of cases, persistent SARS-CoV-2 replication results in an accelerated accumulation of adaptive mutations that confer escape from neutralizing antibodies and enhance cellular infection. This may lead to the evolution of extensively mutated SARS-CoV-2 variants and introduce an element of chance into the timing of variant evolution, as variant formation may depend on evolution in a single person. Whether long COVID is also caused by persistence of replicating SARS-CoV-2 is controversial. One line of evidence is detection of SARS-CoV-2 RNA and proteins in different body compartments long after SARS-CoV-2 infection has cleared from the upper respiratory tract. However, thus far, no replication competent virus has been cultured from individuals with long COVID who are immunocompetent. In this Review, we consider mechanisms of viral persistence, intra-host evolution in persistent infections, the connection of persistent infections with SARS-CoV-2 variants and the possible role of SARS-CoV-2 persistence in long COVID. Understanding persistent infections may therefore resolve much of what is still unclear in COVID-19 pathophysiology, with possible implications for other emerging viruses.
