What term is used for an author who takes overall responsibility for the integrity of a study and its report?

The term used for an author who takes overall responsibility for the integrity of a study and its report is "guarantor." This designation reflects a person's obligation to ensure that the research is conducted and reported ethically and accurately. The guarantor plays a crucial role in upholding the quality and integrity of the findings, representing a commitment to transparency and accountability in the research process.

In many instances, the guarantor is also involved in overseeing the study design, data analysis, and the interpretation of results, ensuring that the conclusions drawn are supported by the data presented. This role is particularly important in preventing issues related to research misconduct, such as fabrication or falsification of data, as it places a point of responsibility that can be held accountable.

The other terms listed may refer to specific roles within a research team, but they do not encapsulate the broader responsibility for the overall integrity of the study and its reporting in the same manner.
