5. Actual results

Results

Coeliac disease by jejunal biopsy: 11/25 (44%) with refractory IDA, 23/67 (34.3%) with non-endocrine short stature, 6/200 (3%) with type 1 diabetes. AGA IgG sensitivity 80.0%, tTG 72.7%; ARA specificity 95.9%, EMA 94.7%.

Absolute risks

not reported

Authors' conclusion

Coeliac disease is more common in these Egyptian risk groups than previously thought; screening is mandatory; biopsy remains the cornerstone.

6. Strengths

  • Egyptian data
  • Biopsy-confirmed

7. Weaknesses

  • Small, selected referral groups
  • Wide CIs (11/25: 26.7-62.9%)

8. Risk of bias

Overall risk of bias

Rationale

Referral selection inflates prevalence.

9. Assessment of the statistical interpretation

Wilson CIs recalculated (stats/C-WHT-02).

10. Relevance to the specific claim

In Egypt, refractory iron-deficiency anaemia in children is often coeliac disease, which requires diagnosis while gluten is eaten.

11. Independent contrary findings

Selected sample.

12. Transferability to Germany and Europe

Moderate.

13. Overall methodological judgement

Regionally relevant, small.
