Automating assignment of HIV+ patients into phenogroups from demography bound phenotype attack rates.
Article in AMIA ... Annual Symposium proceedings. AMIA Symposium, 2024. 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
Evidence based medicine and health data for policy should update statistical data modeling methods to take advantage of at-scale data. One challenge with at-scale data is information segmentation for clinical presentation discovery and cohort assignment. We use gradient boosting machine (GBM) to segment 94,379,175,015 diagnostic clinical events attributable to 283,632,789 Centers for Medicare and Medicaid Services beneficiaries over 22 observation years. Diagnostic events were aggregated into attack rates by demography and Phenome-wide association studies (PheWas) codes. Resulting attack rates were then segmented within a user defined clinical status of interest, in this case HIV status. 1,753,647 HIV+ beneficiaries were considered. The GBM model assigned 19,651,408 PheWas attack rates from 69,133,296 ICD attack rates into phenogroups/nodes.
