在三个生物医学研究机构中，没有迹象表明某一实验室的规模是每位科学家发表论文数量最多或最少的。在一个实验室的出版物数量与实验室规模的散点图中，横坐标表示实验室中科学家的数量，纵轴表示实验室的出版物数量（无论作者数量多少，每篇出版物计数一次），每个实验室用一个点表示。纽约洛克菲勒大学（RU）、伦敦国家医学研究所（NIMR）和贝塞斯达国家癌症研究所（NCI）的散点图都可以用一条穿过原点的直线来很好地描述。这三家机构的直线斜率没有显著差异。在这些规模从1到46名科学家不等的实验室中，无论实验室的规模如何，每增加一名科学家，该实验室的预期年出版物数量将增加约1.1篇。虽然这三所大学的平均实验室规模有显著差异，但正如实验室人口动态的简单模型所预测的那样，每所大学的实验室规模的频率分布可以用0截断的负二项分布来描述。
In three biomedical research institutions, there is no indication of a single laboratory size at which the number of publications per scientist is maximal or minimal. In a scattergram of the number of publications of a laboratory against laboratory size, the horizontal coordinate measures the number of scientists in a laboratory, the vertical axis measures the number of publications from the laboratory (counting each publication once regardless of the number of authors), and each laboratory is represented by one point. Scattergrams for the Rockefeller University (RU), New York, the National Institute for Medical Research (NIMR), London, and the National Cancer Institute (NCI), Bethesda, are each described well by a straight line through the origin. The slopes of the lines for the three institutions are not significantly different. In these laboratories, ranging in size from 1 to 46 scientists, one additional scientist increases the expected annual number of publications of a laboratory by approximately 1.1, regardless of the size of the laboratory. Although the three institutions have significantly different mean laboratory sizes, the frequency distribution of laboratory size in each institution is described well by a 0-truncated negative binomial distribution, as predicted by a simple model of laboratory population dynamics.
