Dental disease among adults with and without HIV in the MACS/WIHS Combined Cohort Study (MWCCS).
Article in BMC oral health, 2026. 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
backgroundOral diseases are prevalent and linked to systemic health outcomes. People with HIV may face elevated oral disease risk, yet data on dental disease in this population remain limited.
methodsIn this cross-sectional study, we analyzed oral health data collected from 2927 participants in the MACS/WIHS Combined Cohort Study (968 women with HIV [WWH], 450 women without HIV [WWoH], 941 men with HIV [MWH], 568 men without HIV [MWoH]) who had intraoral photographs collected and evaluated by dentist-researchers. We used log-binomial regression to examine associations between demographic and clinical characteristics and two outcomes: missing teeth and untreated caries or residual roots, stratified by sex.
resultsAmong 2927 participants (median [interquartile range, IQR] age: WWH, 55.3 years [48.3-61.6]; WWoH, 53.3 [44.8-60.3]; MWH, 55.1 [42.6-62.9]; MWoH, 62.9 [50.1-69.5]), women experienced a higher prevalence of tooth loss and untreated decay than men. Among participants aged 65 years or older, 15% to 21% of women were edentulous (compared with 2% to 3% of men), and 30% to 31% were missing at least a full arch of teeth (compared with 4% to 6% of men). In multivariable analyses, age was a dominant predictor of missing teeth among men (age ≥ 65 vs. <45 years: adjusted prevalence ratio [aPR], 1.49; 95% confidence interval [CI], 1.29-1.73). Income was the strongest predictor of untreated decay among women, more strongly predictive than age (highest vs. lowest income: aPR, 0.11; 95% CI, 0.03-0.43). Disparities by race/ethnicity persisted among men but were absent among women, who experienced extreme poverty and poor outcomes regardless of race/ethnicity. HIV serostatus was not independently associated with either outcome.
conclusionDental disease burden in this population reflected socioeconomic disparities rather than HIV infection. Racial disparities were absent among women, who had uniformly low incomes and poor oral health outcomes across all groups, highlighting substantial barriers to dental care access that warrant policy attention.
