Descriptive Statistics at Paper Level by Laureates and Non-Laureates.

All differences are statistically significant at the P<0.05 level due to large sample size. Number of Authors is calculated after eliminating sole authored records reducing the sample size—Laureate N = 13,104; Non-L. N = 19,221. Nation data is missing for a large number of older papers—Laureates N = 9,165; Non-L. N = 13,076. The total number of international papers (2+) was divided by the total number of papers with country data available to calculate international percent.
Descriptive Statistics at Paper Level by Laureates and Non-Laureates.

鉴于样本量充足，所有组间差异均达到P<0.05的统计学显著性水平。作者数量统计时已剔除独著文献记录，故此样本量有所缩减——获奖者（Laureate）组样本量N=13104；非获奖者（Non-Laureate）组样本量N=19221。大量早期文献缺失国家归属数据——获奖者组有效样本量N=9165；非获奖者组有效样本量N=13076。国际合作论文（作者来自至少2个国家，记为2+）的总数量除以拥有国家归属数据的论文总数，即可计算得到国际合作占比。
