Table 2.

Global stutter analysis was performed for 22 forensic markers on a subset of the Austrian population sample (n = 50). Samples were selected according to the total number of reads and divided into two categories (selection criteria: category I: ≤ 63,500 reads; category II: ≥ 199,000 reads). Bold numbers denote stutter values exceeding 20%. In general, mean stutter values were comparable to CE-based stutter heights
