When designing the study, the endpoints, the study population and the basic design are defined. ACOMED statistics brings biometric aspects here, e.g. on interim analyzes, and makes initial considerations about the sample size. At the end is the synopsis of the protocol.
ACOMED statistics then contributes to the preparation of the study protocol, especially the statistics chapter. The determination of the sample size (number of cases) is finalized.
One of the strengths of ACOMED statistics is very good knowledge of and experience with measurement methods (e.g. laboratory) or measurement instruments (e.g. questionnaires), because ACOMED statistics has also supported statistical validation studies. Are the endpoints measured correctly, precisely and sensitively?
The statistical evaluation plan (SAP) is usually created during patient recruitment. All static issues are defined in SAP and the SAS programming is fully specified. Here ACOMED statistics offers the SAS programming of the (empty, i.e. filled with placeholders) table shells.
In addition, ACOMED statistics takes over inspection tasks of the documents, e.g. the registration forms or input masks for eCRF.
