Extended Data Fig. 1: Sensitivity analysis of slope (β) estimates for the linear terms of a subset of variables across all versions of the input data.

Dot size is the size of the β value, with colour representing direction (red, positive; blue, negative). Each row label represents the name of the fixed effect. The column headings represent the subset of data used: ‘all-records’, all data (n = 4,346); ‘intro-and-unk.’, all data, but one record per species-location event (n = 3,762); ‘intro-only’, detailed introductions only (n = 1,784); ‘intro-last-only’, detailed introductions, but one record per species-location event (n = 1,530). The number at end of each column heading indicates the relative size of the buffer used to impute establishment status (Methods).
