Predictive Models to Identify Individuals With HIV at Risk of Unsuppressed Viral Load Using Routine Public Health Data.
Article in Journal of acquired immune deficiency syndromes (1999), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundEffective antiretroviral therapy to maintain durable viral suppression is key to ending the HIV epidemic in the United States. We evaluated the ability of machine learning algorithms to predict people with HIV (PWH) at risk of unsuppressed viral load.
settingRetrospective study among PWH from San Diego County (n = 18,916). The study used reported public health HIV data (2017-2022) to predict the outcome of HIV viral load >200 copies/mL during a year-long prediction window.
methodsThe data was partitioned by calendar date into two training and one validation datasets to accurately assess performance for predicting future observations. A random forest model was used to generate outcome predictions for the overall population and stratified by race. Mediation analysis was undertaken to assess underlying causality.
resultsThe model had an area under the receiver operating characteristic curve of 82.2 (95% CI: 79.3 to 85.0), a sensitivity of 33.8% (95% CI: 28.6 to 39.0), and specificity of 96.9% (95% CI: 95.7 to 97.2) corresponding to a positive predictive value of 55.7% (95% CI: 48.7 to 62.8) and negative predictive value of 91.7% (95% CI: 90.6 to 92.8). The area under the receiver operating characteristic was similar across races. Prior viral load characteristics were identified as the most important variables; however, they partially acted as mediators of underlying demographic (eg, race) and HIV infection risk (eg, injection drug use).
conclusionsMachine learning algorithms using mandatory reported public health HIV data can predict which PWH will have future unsuppressed viral load. Future work will assess its clinical utility compared to existing data-to-care initiatives.
