A practical AttendMe guide

How to compare studies that seem to disagree

Check whether two papers answer the same question before weighing their conclusions.

AttendMe editorial resource · Updated

01

Define the common question

Write the population, intervention, comparator and outcome you want to compare.

02

Separate reports from studies

A follow-up report or subgroup analysis is not a separate randomised comparator. Check whether reports describe the same trial.

03

Compare like with like

Look at baseline risk, follow-up, endpoints and study setting before comparing effect estimates.

04

Record unresolved differences

Use the comparison worksheet to show what differs and what remains uncertain. Preserve the source for each numerical result.

05

A worked workflow example

Start with one paper and investigate why related studies might appear different. AttendMe Compare finds similar papers from a starting paper. Inspect the studies it actually uses before drawing a comparison.

  1. Your input

    Start with the TEAM trial, PMID 36286256. Ask: 'Do these studies examine the same intervention, adult ICU population and outcome over the same follow-up?' Keep any specific second paper's identifier beside it in the comparison worksheet.

  2. In AttendMe

    Open Library, choose Critical Care and find the saved starting paper in My Library. Select Compare. Comparative Analysis identifies the similar studies actually used. It does not guarantee a particular second paper. If that paper is absent, appraise it separately and compare both sources in the worksheet.

  3. What you inspect

    Read Studies at a glance, How they fit together, Certainty across these studies and Gaps. Open each returned PMID or DOI. Check whether reports describe separate trials or the same trial. Compare endpoints and follow-up before weighing any difference. A similarity percentage is not an evidence-quality rating.

  4. Your reviewed result

    Example comparison row: 'Study identity: verify each PMID. Endpoint: copy its source definition. Follow-up: record the period. Supporting passage: locate it. Comparability: explain the difference.' Leave unavailable details unresolved. The reviewed result states what differs and which evidence would resolve the question.

06

Before you reuse the result

Use this final check to decide whether the work is ready to discuss, save or continue. A useful output preserves its evidence, its scope and the questions it could not answer.

  • The comparator list identifies every paper the analysis used.
  • Follow-up reports are not counted as independent trials.
  • Each comparison preserves its endpoint, follow-up and source passage.
  • The conclusion explains uncertainty without declaring a treatment winner.
