    To check the effect size, Cohen ‘s d was calculated (Equation 2).where, M: mean, n: sample size, SD: standard deviation Probability distributions of pairwise cosine similarities were calculated by binning frequencies (bins = 25), and their Jensen-Shannon divergence (with base 2) was calculated using the jensenshannon function available in SciPy [v1.7.0]31. p-value was calculated using bootstrapping with 1000 iterations.

    For calculating 95% confidence interval, we calculated Jensen-Shannon divergence (JSD) and Cohen ‘s d for each bootstrap iteration.

    Results from OddPub: We did not detect open data. We also did not detect open code. Researchers are encouraged to share open data when possible (see Nature blog).

    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    This study has a few limitations. Since this study is based on publicly available data from the GISAID database, it may carry biases associated with sequencing disparities across countries and reporting delays. Though there is extensive genomic surveillance, there is a lack of clinical annotation of the genomes, limiting our ability to assess the clinical impact of the country-specific differences in the variants. The GISAID database does not record mutations in the recently discovered ORFs in the SARS-CoV-2 genome such as ORF10, ORF9b, and ORF9c. The assignment of the mutations in these ORFs may reveal further differences between SARS-CoV-2 variants. Though mass vaccination efforts are underway around the world, there are huge differences in the population immunity of countries due to the differences in the vaccines approved regionally and the extent of vaccination coverage in populations. These differences contribute to the risk of emergence of new SARS-CoV-2 variants and continued genome-surveillance is imperative for developing comprehensive global and country-specific preventive and therapeutic measures to end the ongoing pandemic.

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
