For lower-powered GWAS datasets or those with sparse association signals, INFERNO uses GWAS summary statistics to identify all significant or almost significant variants within a user-defined window around each tagging variant ( p -value expansion).

The sentences
For lower-powered GWAS data, the p -value expansion enables the analysis of nominally significant signals near genome-wide significant signals by taking the full GWAS summary statistics as well as LD structure into account, potentially capturing causal variants underlying association signals.
