US Health Resource Utilization and Cost Burden Associated with Choroideremia.

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
purposeChoroideremia is a progressive, inherited retinal dystrophy that leads to blindness. This study of choroideremia addresses health resource utilization (HRU) and costs from a US payor perspective using insurance claims data. The retrospective analysis used data between January 2013 and December 2018 from the IBM MarketScan Commercial, Medicare Supplemental, and Multi-State Medicaid Databases. PATIENTS AND
methodsPatients having ≥1 claim with an International Classification of Diseases, Ninth or Tenth Edition, diagnostic code for choroideremia (363.55/H31.21) were included; a control group was matched 3:1 to the choroideremia group. Patients were followed for ≥6 months. All-cause HRU and costs were compared between cohorts using generalized linear models adjusted for Charlson Comorbidity Index.
resultsThere were 199 and 597 patients in the choroideremia and control groups, respectively; the choroideremia group had a higher mean baseline Charlson Comorbidity Index (0.47 vs 0.26). The choroideremia group had a significantly greater mean number of hospital admissions (0.09 vs 0.06), outpatient visits (22.33 vs 11.22), and emergency department visits (0.41 vs 0.26) per patient per year than the control group. The choroideremia cohort had higher all-cause total annualized costs than the control cohort ($15,372 vs $9285), primarily driven by outpatient visits ($8306 vs $4702). This trend was observed across age categories, particularly among patients aged 20 to 44 years (choroideremia, $14,544 vs control, $5953).
conclusionThe choroideremia group had higher all-cause HRU and total costs versus the control group. These findings provide economic context around HRU associated with choroideremia and help assess the potential impact of novel treatments.
