Distribution of compounds over different indicators in the PubChem database. (a) The size of records. Indicators are minimal (0) for (68.7 ± 0.4)% of compounds. (b) The number of vendors. Indicators are absent (0) for (59.1% ± 0.4%) of compounds. Very rare data for the most abundant compounds (from 14 to 75 vendors, total 0.1%) are not shown. (c) The number of patents. Indicators are absent (0) for (78.0% ± 0.4%) of compounds. Very rare data for the most abundant compounds (from 17 to 23036 patents, total 0.3%) are not shown. (d) The number of sources. Indicators are minimal (1, the database itself) for (75.4 ± 0.4)% of compounds. Very rare data for most abundant compounds (from 6 to 20 sources, total 0.3%) are not shown.
