Funding and Conflicts of Interest in a Research Paper
Funding disclosures explain part of the setting in which research was produced. Learn to distinguish study support from wider author interests, examine sponsor involvement and use disclosures to guide specific questions without…
-
Observational Studies and Randomised Comparisons
Observational studies describe what happens without assigning exposure at random. Randomised comparisons use a different allocation process. Learn what each design can contribute, how confounding affects interpretation and why an association needs…

Publication Dates, Corrections and Updated Research Records
A saved PDF may no longer represent the current scientific record. Learn how to distinguish online publication from later issue dates, inspect correction notices and preserve a clear version trail when researching…
-
Reading a Systematic Review Beyond Its Abstract
A systematic review is valuable because its methods show how evidence was found and assessed. Learn to inspect the review question, study selection and synthesis so that the headline conclusion does not…

Preprints and Peer-Reviewed Papers: Recording Publication Status
Publication status is part of a research record. This guide explains what to check when a peptide manuscript appears as a preprint, later receives peer review or changes between versions, and why…
-
Replication and the Limits of a Single Study
A single study provides one view of a scientific question. Learn how replication, computational checks and comparisons across models contribute different kinds of evidence, and how to assess a disagreement without treating…
-
Multiple Endpoints: Which Question Was the Study Designed to Answer?
A study can measure many outcomes, time points and subgroups. This guide explains how to identify the original research question, locate an analysis plan and interpret a highlighted result without losing sight…
-
Confidence Intervals in Scientific Results
Confidence intervals add information that a point estimate alone cannot provide. Learn how to read their range, avoid common probability errors and recognise the uncertainties that remain outside the statistical model when…
-
Effect Size and Statistical Significance
A small P value does not describe how large an effect is or whether it matters. This guide explains why effect estimates, measurement scales and uncertainty belong together when evaluating a peptide…
-
Sample Size, Precision and the Strength of a Research Claim
A large headline total can hide a small number of independent observations. Learn how sample size relates to precision, why repeated measurements need careful interpretation, and what a reported calculation can tell…
-
Blinding and the Measurement of Experimental Outcomes
Knowing which group received an experimental intervention can affect handling, measurement and analysis. Learn to identify who was blinded, at which stage and by what method, so that a brief research summary…

Randomisation and the Interpretation of a Study Comparison
Randomisation helps create a fair comparison, but the word alone tells readers little about implementation. This guide explains sequence generation, allocation concealment and baseline differences, with practical questions for reading laboratory studies…
