Summary of findings 3. Comparison 3: provision of electronic health information via different interfaces: full‐service versus self‐service.

Provision of electronic health information via different interfaces: full‐serviceversus self‐service The full‐service interface was unique in 2 aspects: 1. included a search engine that returned critically appraised articles rated by physicians; 2. included push information, e.g. email alerts on topics of interest to the practitioner
Population: physicians Settings: primary care or internal medicine practices Intervention: full‐service interface Comparison: usual interface
Outcomes	Results (mean logins/month/user)		Number of studies	Number of sites (number of participants)	Quality of the evidence (GRADE)
Changes to professional behavior ‐ use of EHI	IG 1.66 to 1.84	CG 2.05 to 1.46	1	10 communities (clusters), IG 5 (98); CG 5 (105)	⊕⊕⊕⊝
	Change in the rate of logins/month/user, baseline vs. intervention period: 0.77 logins/month/user (95% CI 0.43 to 1.11), favoring IG (full‐service group)
GRADE: GRADE Working Group Grades of Evidence ⊕⊕⊕⊕ High quality: We are confident that the true effect lies close to that of the estimate of effect. ⊕⊕⊕⊝ Moderate quality: The true effect is likely to be close to the estimate of effect, but there is a possibility that it may be substantially different. ⊕⊕⊝⊝ Low quality: The true effect may be substantially different from the estimate of effect. ⊕⊝⊝⊝ Very low quality: Any estimate of effect is very uncertain. CG: control group; CI: confidence interval; EHI: electronic health information; IG: intervention group.
We downgraded the evidence because there is only 1 study assessing this comparison.
