12. Type of study

Therapeutic studies examine which therapy is appropriate for a specific medical condition, and diagnostic studies examine the proper diagnostic strategy for a specific condition. Prognostic studies focus on the factors that influence the course of a disease for a patient, while epidemiological studies investigate the overall factors for a specific disease. Studies involving non-human observation units are pre-clinical studies. A meta-analysis is a statistical analysis comprising several studies.

14. High throughput data

High throughput data in this context means molecular biological measurement methods that are applied to quantify thousands of characteristics for an observation unit (cell, cell culture, tissue, patient, ...). These research methods are often identified by the suffix "omics", e.g. genomics, transcriptomics, proteomics. Commonly used measurement methods are sequencing, mass spectroscopy and microarrays.

Tick the box if the analysis of such data is an essential part of the study and you would like advice on this. This information will be taken into account when assigning the consultant.

14. Information about the study design

Please indicate which criteria are applicable to your study. In a prospective study, the data that are to be analyzed were collected according to the objectives or the study protocol. Retrospective studies, on the other hand, analyze data that was collected without prior planning, i.e., before a study protocol was created. Controlled studies examine and compare two groups that are treated with the same intervention, where the control group is either a secure (e.g., an established therapy) or a neutral (e.g., placebo) variable.

In randomized studies, the study participants are assigned randomly to one of the groups. In addition, the handling of the group assignment of the patients can be either open, i.e., both the physician and the patient know which group the patient belongs to, single-blind, i.e., only the physician is informed, or double-blind, i.e., neither the patient nor the physician know which group a patient has been assigned to. Monocentric studies are conducted within a single institution, e.g. in a department.
