<h3>Objective:</h3> Existing endoscopy-based data on gastro-oesophageal reflux disease (GORD) in the general population are scarce. This study aimed to evaluate typical symptoms and complications of GORD, their associated risk factors, a representative sample Italian population. <h3>Methods:</h3> 1533 adults from two villages were approached undergo symptom assessment using validated questionnaire upper gastrointestinal endoscopy. Data obtained 1033 individuals (67.4% response rate)....

Background In biomedical research, it is often desirable to seek consensus among individuals who have differing perspectives and experience. This important when evidence emerging, inconsistent, limited, or absent. Even research abundant, clinical recommendations, policy decisions, priority-setting may still require agreement from multiple, sometimes ideologically opposed parties. Despite their prominence influence on key methods are poorly reported. Our aim was develop the first reporting...

Abstract Background Structured, systematic methods to formulate consensus recommendations, such as the Delphi process or nominal group technique, among others, provide opportunity harness knowledge of experts support clinical decision making in areas uncertainty. They are widely used biomedical research, particular where disease characteristics resource limitations mean that high-quality evidence generation is difficult. However, poor reporting reach a – for example, not clearly explaining...
