Abbreviation: SFED, 6-food elimination diet.
The risk in the intervention group (and its 95% CI) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).
Used <10 eos/hpf for definition of remission. Studies with a cutoff of <15 eos/hpf will likely underestimate the response rate within the pooled results and therefore strengthen the assumed estimate of effect (Kagalwalla et al62).
Measured SF-36 (Gonsalves et al63).
15 of 26 subjects did SFED + foods with + SPT/APT (Henderson et al64).
Also eliminated rice + corn (Lucendo et al64).
Also eliminated foods with + SPT/APT (Colson et al65).
Excluded subjects with + IgE tests before enrollment. The response rate is lower and therefore likely underestimates the effect estimate in the pooled results (Rodriguez-Sanchez et al66).
Only subjects with <5 eos/hpf (“complete” remission) (Philpott et al67).
Combined clinical and histopathologic remission; estimated for SFED based on 2-, 4-, 6-FED step-up protocol (Molina-Infante et al67).
Did not include Wolf 2014 in analysis to avoid duplicate subjects (Reed et al68).
When compared to historical controls, a very large effect estimate is likely. However, the evidence certainty was not rated up due to concerns of possible residual confounding and/or indirectness.
