Corrigendum: Hidden figures: Revisiting doping prevalence estimates previously reported for two major international sport events in the context of further empirical evidence and the extant literature

Corrigendum on Hidden figures: Revisiting doping prevalence estimates previously reported for two major international sport events in the context of further empirical evidence and the extant literature By Petróczi A, Cruy M, de Hon O, Sagoe D and Saugy M (2022) Front. Sports Act. Living 4:1017329. doi: 10.3389/fspor.2022.1017329

Correction to Table/Figure

In the published article, there was an error in table 4 as published. There was an error in the estimated % of admitted doping (d) for H2: 0.3031 ± 0.0800 was erroneously listed for both the estimated % of admitted doping (d) and for the estimated % of noncompliance (nc). The correct value for the estimated % of admitted doping (d) is 0 and the value of the estimated % of noncompliance (nc) remains 0.3031 ± 0.0800. The corrected Table 4 and its caption Estimated use of prohibited performance enhancing substances and/or methods at WCA (12-month prevalence) appear below.

In Figure 3: Comparison of doping prevalence estimates for WCA and PAG between the two survey formats, and with literature evidence. Data extracted from Table 1 using the most relevant figure (i.e., elite level and current/last season/past 12 months) when multiple estimates are reported. In the figure legend ‘ABP Blood doping WAC 2021’ should read as ‘ABP Blood doping WCA 2011’.

Incorrect Supplementary Material

In the published article, there was an error in Supplementary Material 2: Detailed prevalence and noncompliance estimations, Table 2.1: Detailed prevalence and noncompliance estimations for WAC and PAG, 2011. Incorrect values were reported for ‘Estimation’. The correct material statement appears below.
