Extended Data Fig. 6: Total scores of metadata completeness.
From: Global landscape of SARS-CoV-2 genomic surveillance and data sharing
We developed a scoring system to assess the metadata quality of each country based on the metadata completeness of ten key variables, including subnational information, sample strategy, specimen source, sequencing technology, date of collection, sex, age, patient status, vaccinated status, and lineage (the weight of each variable is one point, and the total scores are 10 points). The right panel shows the expanded European region. Administrative boundaries were adapted from the GADM database.
