5 Add Assessment Domains with custom text, category, appraisal level, guidance, and optional sub-domains.

Example: Editing ROBINS-I Tool

ROBINS-I (Risk Of Bias In Non-randomized Studies - of Interventions)
Domain 1: D1: Bias due to confounding – Consider whether the most important confounding domains were controlled for in design or analysis.
Domain 2: D2: Bias in selection of participants into the study
Domain 3: D3: Bias in classification of interventions
Domain 4: D4: Bias due to deviations from intended interventions
Domain 5: D5: Bias due to missing data
Domain 6: D6: Bias in measurement of outcomes
Domain 7: D7: Bias in selection of the reported result
Low Some concerns High
Overall Judgment Scale: Grade A: High Certainty | Grade B: Moderate Certainty | Grade C: Low Certainty
Export options: Each QA tool can be exported as DOCX, PDF, or CSV for external documentation or protocol appendices.

6. Extraction Form Planning

Data Extraction 1‑to‑Many Repeater Logic 60 min

📊 Data Extraction Forms Dashboard

Design structured forms to ensure consistent data collection across all included studies. For qualitative meta‑aggregation, use the Repeater Field to capture multiple findings per study.

1 Click "Create New Form" → enter Form Name and Description.
2 Optionally start from a template (blank or pre‑defined structure).
3 Add fields: Field Label, Field Name (machine‑friendly), Field Type (Text, Textarea, Number, Dropdown, Date, Checkbox).
4 Toggle "Repeater?" to YES for fields that require 1‑to‑many entries (e.g., multiple qualitative findings per study).
5 Save form – it becomes available for reviewers during the Conducting phase.
⭐ Major Feature: 1‑to‑Many Repeater Logic for Qualitative Evidence
In qualitative systematic reviews (JBI meta‑aggregation), a single study may contribute multiple themes, categories, or findings. The Repeater Field allows reviewers to click "Add Another Row" to extract unlimited findings from one source. When you design an extraction form, set the field type as Repeater Group – inside it, include fields like "Theme Name", "Illustrative Quote", "Participants' Voice", and "Level of Credibility". The system will group these during synthesis.

Edit Extraction Form Example

Order 2 Study Design (Text) – Repeater? No
Order 3 Intervention Group Description (Textarea) – Repeater? No

Creating a Repeater Group for Qualitative Synthesis

REPEATER GROUP ENABLED
Field Label: Qualitative Findings (Repeater Group)
Inside Repeater – fields that can be repeated multiple times per study:
  • Theme/Category Name (Text) – e.g., "Barriers to adherence"
  • Illustrative Quote (Textarea) – verbatim quote from participants
  • Credibility Rating (Dropdown) – Unequivocal / Equivocal / Unsupported
  • Country / Setting (Text)
During extraction, reviewers click "Add Another Row" to insert a new set of fields for each unique finding.

For qualitative repeater forms, reviewers see a dynamic "Add Another Finding" button below each study.
📌 Two-Phase Extraction (Study Characteristics + Outcome Data)
RevProHub now supports separation of static study characteristics (author, year, design) from repeatable outcome data (effect sizes, events, qualitative findings). This ensures cleaner datasets for meta‑analysis or thematic synthesis.
🧪 Hands-On Activity: Tool Planning (QA & Extraction) – 35 min
  1. Create a QA tool: Navigate to Planning → Quality Appraisal Form Planning. Click "Add New Tool". Select a template (e.g., "Cochrane RoB 2 for RCTs"). Name it "My RoB2 Training Tool". Add domain rating scale (Low / Some concerns / High) and overall judgment (High certainty / Moderate / Low). Save.
  2. Add a custom domain: Edit the tool → Add a new domain: "D6: Blinding of outcome assessment" with guidance text. Save changes.
  3. Create an Extraction Form with Repeater: Go to Extraction Form Planning → Create New Form. Name: "Qualitative Synthesis - Themes". Add fields: "Study ID" (Text), "Country" (Text), then add a Repeater Group. Inside the group add: "Theme Name" (Text), "Illustrative Quote" (Textarea), "Credibility" (Dropdown with options: High/Moderate/Low). Set Repeater = YES for the group.
  4. Preview the form: Click "View Form" to see how reviewers will see the "Add Another Row" button.
  5. Export the QA tool: From QA Tools dashboard, click export (PDF) – observe how domains and rating scales are formatted.

Debrief Questions:

  • Why is the Repeater logic essential for qualitative evidence synthesis compared to traditional flat extraction forms?
  • How does pre‑defining domain rating scales improve consistency across multiple reviewers?
  • What is the advantage of separating Study Characteristics from Outcome Data (two‑phase extraction)?
  • How do these planning tools (QA + extraction) link to the later Conducting phase modules?
Integration with Protocol & Conducting: QA and extraction forms created in the Planning phase are automatically available during the Conducting phase (Quality Appraisal and Data Extraction stages). Changes to forms after extraction begins are restricted to maintain data integrity – so plan carefully.
Two-Phase Extraction Architecture:
Phase 1 – Study Characteristics (static, extracted once per study): Author, Year, Country, Design, Funding source.
Phase 2 – Outcome Data / Qualitative Findings (repeatable): Effect sizes, confidence intervals, themes, quotes. This separation enables efficient subgroup analysis and meta‑aggregation.

Next session transition: After completing tool planning (QA + extraction), the project moves to the Conducting Phase where these instruments are deployed for risk of bias assessment and data extraction.


Next session: Importing Studies, Deduplication, and Preparing for Screening (Conducting Phase).
