Separate eligibility, version changes, and duplicate participant data when a study appears before and after journal publication.
Choose the Propensity-Score Target Before Choosing Weights
Connect ATE, ATT and overlap weighting to the population in the research question.
Keep patient, proxy and observer responses distinct
Record who supplied an outcome and avoid silently pooling different perspectives as one measure.
Check questionnaire permissions before implementation
Match the exact instrument, language and administration mode to its current terms of use.
Manage Random Streams in Parallel Simulation Studies
Assign reproducible streams to replicates so parallel workers do not accidentally repeat the same simulated data.
Combine Range Checks with Cross-Field Consistency Rules
Use explicit logical tests to find contradictory research records without automatically deleting unusual values.
Detect Redundant Columns Before Interpreting Regression Coefficients
Check exact dependencies in the fitted design rather than assuming a returned coefficient table identifies every parameter.
Interpret a Ratio of Arithmetic Means Without Calling It a Geometric Ratio
Check the summary definition and meaningful zero before reporting a relative continuous-outcome comparison.
Align questionnaire recall periods with study visits
Check that the reporting window matches the scientific question and remains consistent across assessments.
Forecast recruitment with staggered site activation
Use opening dates, ramp-up and mature site rates to estimate calendar recruitment capacity.
Define recurrent events before choosing a model
Specify episode boundaries, risk periods and terminal events so repeated outcomes represent the intended process.
Audit bandwidth choices in regression discontinuity
Check the assignment threshold, local support and sensitivity before interpreting a discontinuity.
