Figure 1

CIs broken down by sector. For each sector separately, the CI distribution is illustrated via box-plots, showing minimum CI, 25th, 50th and 75th percentiles, and maximum CI of each sector. Numbers in parentheses at the end of each sector name indicate the sample size as per Table 1. Yellow line and numerical labels show the (geometric) average CI per sample. SEMs of average CIs (Methods) are small, between 7–13% for all sectors, except for the sector Commercial equipment and capital goods which has an SEM of 29% (SEMs not plotted).
