Equivalence of reported detection limits in anodic stripping voltammetry: a critical systematic review of estimation practice against international standards

A critical systematic review of how limits of detection are estimated and reported in recent anodic stripping voltammetry studies of Pb(II) and Cd(II). A frozen Scopus corpus of 416 records (search 9 September 2026) was sampled reproducibly; 44 full texts were coded independently by two coders on a two-axis scheme recording the quantity named as the basis of the estimate and the completeness of the statement. This project holds the protocol, the codebook, both coders' raw coding sheets, the written ratification of all coding decisions, the dataset freeze record, and the scripts that regenerate every reported value. The registration filed from this project is retrospective: the protocol was written before coding began, but registration followed the completion of coding.
