Strategic site selection for placement of HIV early infant diagnosis point-of-care technology within a national diagnostic network in Lesotho.
Article in African journal of laboratory medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNew technologies for rapid point-of-care (POC) diagnostic tests hold great potential for improving the health outcomes of HIV-exposed infants. POC testing for HIV early infant diagnosis (EID) was introduced in Lesotho in late 2016. Here we highlight critical requirements for selecting routine POC EID sites to ensure a sustainable and optimised EID diagnostic network.
interventionLesotho introduced POC EID in a phased approach that included assessments of national databases to identify sites with high test volumes, the creation of local networks of sites to potentially increase access to POC EID, and a standardised capacity assessment to determine site readiness. Potential site networks comprising 'hub' testing sites and 'spoke' specimen referring sites were created. LESSONS LEARNT: After determining optimal placement, a total of 29 testing facilities were selected for placement of POC EID to potentially increase access to 189 facilities through the use of a hub-and-spoke model. Site capacity assessments identified vital human resources and infrastructure capacity gaps that needed to be addressed before introducing POC EID and informed appropriate POC platform selection. RECOMMENDATIONS: POC placement involves more than just purchasing the testing platforms. Considering the relatively small proportion of sites that can be eligible for placement of a POC platform, utilising a hub-and-spoke model can maximise the number of health facilities served by a POC platform while reducing the necessary capacity building and infrastructure investments to fewer sites.
