The relationship between household economic poverty and trachomatous trichiasis using the asset index, self-rated wealth index and peer-rated wealth index, stratified by age, sex, marital status and vision.

We merged “richest/very wealthy” and “rich/wealthy” with “middle” because of small numbers at these highest extremes of the distribution, to create a combined “middle & above” category in the three socio-economic status indexes, to facilitate data modelling. Analysis was done using logistic regression for trend, adjusted for clustering using robust standard errors method. Using the Benjamini and Hochberg method, only tests with a p-value below 0.0053 have a False Discovery Rate of <5%.
a adjusted for age, sex, marital status and highest family education.
b adjusted for age, marital status and highest family education.
c adjusted for age, sex and highest family education.
‡To classify participants into young and old age groups, the median value of age was used as a cut-off point.
* Unmarried includes: single, divorced and widowed.
† VI includes: moderate visual impairment, severe visual impairment and blindness. Cont = Controls; VI = Visual impairment.
