Quantitative HIV-1-specific antibodies as predictors of peripheral blood cell-associated HIV-1 DNA concentrations.
Article in AIDS (London, England), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01418014 (Adolescent Master Protocol), which is not on this map. Cited by 2 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.

Abstract
objectiveThis study evaluated HIV-1 antibody levels as predictors of cell-associated HIV-1 DNA levels in perinatally infected (PHIV) children with long-term viral suppression on antiretroviral therapy (ART).
designHIV-1 antibody and HIV-1 DNA levels were measured in blood specimens from 61 children and adolescents from the Pediatric HIV/AIDS Cohort Study: Adolescent Master Protocol. Twenty perinatally HIV-1-exposed, uninfected children studied through 2 years served as controls.
methodsHIV-1 IgG antibodies to six HIV-1 proteins were measured by quantitative ELISA; HIV-1 DNA levels were measured by droplet digital PCR.
resultsAmong 13 children with viral suppression at less than 1 year, antibodies to gp160 and gp41 were low but stable longitudinally; antibodies to p17, p24, and RT decreased, and antibodies to p31 were low or undetectable. Among 48 children with viral suppression between 1 and 5 years, antibody levels to all six HIV-1 proteins were higher than in children with earlier viral suppression and remained high over time. A receiver operator curve approach identified gp41 and gp160 as useful predictors of HIV-1 DNA less than 10 or less than 100 copies per million PBMC (cpm); C-statistics including all antibodies ranged from 0.75 to 0.77. An ensemble learning approach also identified gp41 and gp160 as important predictors of HIV-1 DNA less than 10 or less than 100 cpm; area under the curve estimates utilizing all HIV-1 antibodies ranged from 0.70 to 0.81.
conclusionQuantitative HIV-1 gp41 and gp160 antibody levels may serve as rapid, inexpensive screening tools for low PBMC HIV-1 DNA levels in children with viral suppression on ART, facilitating inclusion into remission protocols.
