| Summary of Findings | Language restrictions did not appear to bias the estimates of a conventional intervention’s effectiveness but did affect the results of a complimentary and alternative systematic review. If languages other than English reports were excluded this resulted in a reduced intervention effect, 63% on average (difference in the ratio of odds ratios of intervention = 1.63; 95% confidence interval: 1.03 to 2.60). |
