Concentration curves for total costs, total costs as a proportion of pre-TB annual household income and catastrophic costs due to TB diagnosis, stratified by Axshya SAMVAD and non-Axshya SAMVAD groups, among TB (new sputum-smear-positive) affected households in India, 2016–2017*. SAMVAD: sensitisation and advocacy in marginalised and vulnerable areas of the district; Axshya SAMVAD: an active case finding strategy under project Axshya implemented by The Union, South East Asia office, New Delhi, India, across 285 districts of India; TB: tuberculosis; AHI: annual household income. *For the indicator ‘total costs’, we assumed equity if the concentration curve/index revealed significant distribution across the richest quintiles (positive concentration index, 95% CI not including zero). For the indicators, ‘total costs as a proportion of pre-TB annual household income’ and ‘catastrophic costs’, we assumed equity if the concentration curve/index revealed equal distribution across the quintiles (concentration curve not significantly different from the line of equality).
