Addendum (5-15-2009)

It has been brought to our attention that Ranjit K Chandra may be involved in fraudulent publications (2;3). Dr. Chandra is an author of a primary study (4) included in our update meta-analysis on the association of breastfeeding and asthma risk published in AHRQ Evidence Report Number 153 (1). To assess the impact of this potentially fraudulent study, we repeated the meta-analysis by removing this study. Our original meta-analysis was conducted with and without a study that reported a very large adjusted odds ratio (5). Our re-analysis excluding Chandra 1991 and Wright 2001 (the one with the very large adjusted odds ratio) showed that the overall summary odds ratio remains significant (adjusted OR 0.63; 95%CI 0.45 – 0.89) (Figure 1). Our re-analysis excluding Chandra 1991 but including Wright 2001 showed that the overall summary odds ratio remains non-significant (adjusted OR 0.86; 95%CI 0.62 – 1.18) (Figure 2). These findings are similar to what were reported in the AHRQ Evidence Report. We conclude that excluding Chandra 1991 from our meta-analysis does not affect conclusions concerning breastfeeding and asthma risk made in the report.
