Utility of the International HIV Dementia Scale for HIV-Associated Neurocognitive Disorder.
Observational study in Journal of acquired immune deficiency syndromes (1999), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundWe assessed the utility of the International HIV Dementia Scale (IHDS) in detecting HIV-associated neurocognitive disorder (HAND) in Uganda in antiretroviral (ART)-naïve and ART-experienced adults.
settingA longitudinal observational cohort study in Rakai, Uganda.
methodsThree hundred ninety-nine HIV+ ART-naïve adults underwent neurological, functional status, and neuropsychological assessments including the IHDS. Three hundred twelve participants who initiated ART were re-evaluated after 2 years. HAND stages [asymptomatic neurocognitive impairment, mild neurocognitive disorder, and HIV-associated dementia (HAD)] were determined based on Frascati criteria using local normative data. Sensitivity, specificity, and area under the ROC curve were determined for various IHDS thresholds (≤9, ≤ 9.5, and ≤10).
resultsAt baseline, the participants' mean age was 35 years (SD ± 8), 53% were men, and 84% had less than a high school education. At baseline, sensitivity for detecting any HAND stage, symptomatic HAND [mild neurocognitive disorder, HAD], and HAD alone were maximized at IHDS ≤10 (81%, 83%, 92%, respectively). Among 312 individuals who returned for the 2-year follow-up and had initiated ART, a score of ≤10 provided a lower or equal sensitivity for detecting different stages of HAND (all HAND: 70%; symptomatic HAND: 75%; HAD: 94%). The area under the ROC curve was higher for ART-experienced versus ART-naïve individuals.
conclusionsThe IHDS is a potentially useful screening tool for neurocognitive impairment in rural Uganda for both ART-naïve and ART-experienced adults. A cutoff ≤10 demonstrates higher sensitivity for more severe HAND stages compared with less severe HAND. Future studies should focus on potential modifications to the IHDS to improve its specificity.
