Time spent with HIV viral load above 1500 copies/ml among patients in HIV care, 2000-2014.
Observational study in AIDS (London, England), 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveSexual HIV transmission is more likely to occur when plasma HIV RNA level (viral load) exceeds 1500 copies/ml. We assessed the percentage of person-time spent with viral load above 1500 copies/ml (pPT >1500) among adults with HIV in care.
designObservational cohort in eight United States HIV clinics.
methodsParticipants had at least one HIV Outpatient Study (HOPS) clinic visit and at least two viral loads during 2000-2014. We assessed pPT above 1500 in time intervals between consecutive viral load pairs, overall and by ART status. Trends in pPT above 1500 and associations between pPT above 1500 and chosen baseline demographics and clinical characteristics were analyzed using generalized estimating equations.
resultsThere were 5873 patients contributing 37 794 person-years; 86.0% person-years had prescribed ART, with increasing coverage over time. Over 2000-2014 pPT above 1500 was 24.2%, decreasing from 38.3% in 2000-2002 to 11.3% in 2012-2014. During observation time with ART prescribed, pPT above 1500 was 16.4% overall, decreasing from 29.9% in 2000-2002 to 8.0% in 2012-2014. pPT above 1500 was higher in patients less than 35 vs. at least 50 years old (31.5 vs. 15.6%), women vs. men (30.8 vs. 22.3%), and black vs. white and Latino/Hispanic patients (32.7 vs. 19.9 and 23.7%, respectively). Multivariable correlates of higher pPT above 1500 included no prescribed ART, being younger, non-Hispanic black vs. white, baseline viral load above 1500 copies/ml or lower CD4 count, and baseline public vs. private insurance.
conclusionpPT above 1500 declined during 2000-2014. Results support decreasing HIV transmission risk from persons in HIV care over the last decade, and the need to focus interventions on patient groups more consistently viremic.
