Statistics

Figures

FIG 1 Phylogeny and timescale of P.2 lineage. (A) Maximum-likelihood tree of 1,377 SARS-CoV-2 genomes, including the 180 new Brazilian genomes generated in this work. We randomly sampled one genome/week/country from available samples in GISAID with collection dates ranging from May to November. Brazilian sequences with collection dates from May to November were all added to the data set (see Table S2). We ran IQTree 2.0.3 (10) under a general time-reversible (GTR) model of nucleotide substitution (11) with empirical base frequencies and invariant sites. Tips are colored according to their origin. Genomes generated from this work are red, other Brazilian genomes are blue, and genomes from other countries are not colored. Gray areas represent the three clades where Brazilian viruses are concentrated. The emergent lineage identified in this work, P.2, is in a dark-gray box and highlighted with red branches. The approximate likelihood ratio test (aLRT) support value for the branch holding P.2 monophyly is shown. (B) A time-scaled tree of clade II was estimated under a strict molecular clock in BEAST v.1.10.4 (12) using the GTR+I (11) nucleotide substitution model and assuming an exponential growth tree prior and a normal prior for the clock rate (mean = 8 × 10−4 and standard deviation = 0.1 × 10−5). The convergence of the Markov chain Monte Carlo chains, which were run at least for 50 million generations and sampled every 1,000th step, was inspected using Tracer v.1.7.1 (13). Maximum clade credibility (MCC) summary trees were generated using TreeAnnotator v.1.10.4 (12). Red circles in the tip nodes represent genomes generated in this work, and blue circles indicate other Brazilian samples. P.2 is identified by the red branches and highlighted in a gray box. The posterior probability of the branch holding P.2 monophyly is shown.

FIG 2 Phylogeny of B.1.1.28 and its alias lineages (P.1 and P.2). Maximum-likelihood tree of 993 SARS-CoV-2 genomes. We downloaded all B.1.1.28, P.1, and P.2 high-coverage genomes available in GISAID on 11 February 2021. The phylogeny was estimated using IQTree 2.0.3 (10) under a GTR+F+R3 model chosen by ModelFinder. Brazilian genomes are not tip colored. Viruses from other countries are colored according to their geographical origin (dark blue, South America; light blue, North America; dark green, Europe; light green, Africa; brown, Asia; and orange, Oceania). Gray areas highlight P.1 and P.2 lineages. The aLRT support value for the branch holding P.1 and P.2 monophyly is shown. The tree is rooted with 3 B.1.1 genomes. The chart shows the single nucleotide polymorphisms (SNPs) that characterize P.1 and P.2 lineages.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
