Comparative Effectiveness of Interventions to Improve the HIV Continuum of Care and HIV Preexposure Prophylaxis in Kenya: A Model-Based Analysis.
Article in The Journal of infectious diseases, 2022. 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
backgroundIn Western Kenya up to one-quarter of the adult population was human immunodeficiency virus (HIV)-infected in 2012. The Ministry of Health, Médecins Sans Frontières, and partners implemented an HIV program that surpassed the 90-90-90 UNAIDS targets. In this generalized epidemic, we compared the effectiveness of preexposure prophylaxis (PrEP) with improving continuum of care.
methodsWe developed a dynamic microsimulation model to project HIV incidence and infections averted to 2030. We modeled 3 strategies compared to a 90-90-90 continuum of care base case: (1) scaling up the continuum of care to 95-95-95, (2) PrEP targeting young adults with 10% coverage, and (3) scaling up to 95-95-95 and PrEP combined.
resultsIn the base case, by 2030 HIV incidence was 0.37/100 person-years. Improving continuum levels to 95-95-95 averted 21.5% of infections, PrEP averted 8.0%, and combining 95-95-95 and PrEP averted 31.8%. Sensitivity analysis showed that PrEP coverage had to exceed 20% to avert as many infections as reaching 95-95-95.
conclusionsIn a generalized HIV epidemic with continuum of care levels at 90-90-90, improving the continuum to 95-95-95 is more effective than providing PrEP. Continued improvement in the continuum of care will have the greatest impact on decreasing new HIV infections.
