Erratum to: Prevalence of self-reported tuberculosis, knowledge about tuberculosis transmission and its determinants among adults in India: results from a nation-wide cross-sectional household survey
BMC Infectious Diseases volume 13, Article number: 542 (2013)
Following the publication of our article , we noticed that for calculation of prevalence rates (95% confidence intervals) of self-reported tuberculosis (TB) shown in Table 1 we had not considered sampling weights of complex survey design used in India Demographic Health Survey (DHS). We have re-analysed the data including the sampling weights to calculate weighted prevalence rates and their 95% CIs for self-reported TB in revised Table 1. The revised analysis was carried out using STATA/IC (version 10). The STATA code for revised analysis is available along with this correction article (Additional file 1). We request the readers to consider the corrected Table 1 shown here in place of Table 1 of the original manuscript . In second paragraph of page five of original manuscript, an overall prevalence of self-reported TB should be read as 5.21 per 1000 participants. Revised analysis for Table 1 showed a clear gradient in prevalence of self-reported TB according to wealth index. For example, the richest had a lowest prevalence of self-reported TB (1.92 per 1000 population) and the poorest had the highest prevalence (10.5 per 1000 population). Chi square test was used to assess the statistical significance of the differences in weighted prevalence rates according to each demographic and socio-economic variables. The differences in weighted prevalence rates for all variables were statistically significant (p < 0.01). The readers should also consider the following additional statement in the conclusion: ‘Economically deprived populations are at most risk of TB and should be targeted by TB control programs in India’. We apologise the readers for confusion caused due to wrong analysis and thank Dr. Jason Andrews for drawing our attention towards this error.
