The feasibility of fingerstick blood collection for point-of-care HIV-1 viral load monitoring in rural Zambia.
Article in Global health innovation, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Viral load monitoring for HIV treatment is recommended but not feasible in many settings. A point-of-care test using capillary blood would increase access but may require up to 200 μL of blood to achieve a lower limit of detection of 1000 copies/mL. This cross-sectional study evaluated the feasibility of collecting 200 μL of capillary blood and blood collection preferences among adults in rural Zambia. Adults seeking HIV counseling and testing at Macha Hospital were recruited in 2015. Capillary blood was collected in four 50 μL tubes. Blood collection was categorized as complete (200 μL collected), partial (all tubes filled but <200 μL obtained due to collection techniques), or incomplete (1-4 tubes attempted; <200 μL obtained due to insufficient blood flow). One fingerstick was required for 90% of the 201 participants. A median blood volume of 196 μL was collected. Complete, partial and incomplete collection was achieved in 34%, 59% and 6% of participants. The majority of participants (95%) preferred fingerstick over venous blood collection. A point-of-care viral load test requiring up to 200 μL of blood is feasible in a rural setting but would require training and supervision to ensure that sufficient blood was collected.
