Model is an extension of Pohl1994 and reduced from Wajima2009.Encoding the model from the supplementary files results in 43 species, 82 reactions and 111 parameters. Including the drug (Xa-inhibitor) and drug-Xa complexes results in 46 species, 84 reactions and 115 parameters (+1 dummy variable to change inhibitory kinetic parameters depending on which drug is simulated). The publication lists there being 45 species, 84 reactions and 116 parameters. Publication figure 2 has 45 species present however the complex VIIa:Xa (reaction 51 involving Xa and VIIa) is not shown. This figure also has numerous small errors such as listing IXa:ATIII complex twice (instead of one being XIa:ATIII), not showing XIa:ATIII, typo ('Va' -> Va), typo (IXa + VIIIa -> IXA:'VIIa'). Rate laws for Xa-drug interactions were assumed to be mass action.2018-06-07T00:00:00Z2025-07-14T17:52:29.078Z2025-03-30T22:42:45.186ZMODEL1806070001BIOMD000000034026783501GO:0007596D07086D03213
