1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

backgroundThe World Health Organization recommends house-to-house case searches as an option to evidence whether the elimination of trachomatous trichiasis (TT) has been reached. We sought to determine the number of trachoma-endemic countries and districts that will require either documented full geographic coverage (DFGC) or TT-only surveys.

methodsWe conducted a secondary analysis of data from the Trachoma Atlas to identify evaluation units (EUs) that require house-to-house case searches or TT-only surveys to demonstrate achievement of the elimination of TT.

resultsThere were 1710 EUs with TT above the elimination prevalence target in all trachoma-endemic countries. Of those EUs, 852 (49.8%) do not have a future survey planned and will therefore potentially have to evidence through DFGC or TT-only surveys whether the elimination prevalence target for TT has been reached.

conclusionOf the large number of EUs that require TT-related activities, nearly half of them will need to evidence that every household in the EU has been visited by a case finder and all confirmed cases managed. Given that this is a relatively new way to evidence elimination, and countries face different sociopolitical challenges, cross-country learning and improved guidance is key to support global elimination.
