Treatment Pattern Analysis and Health-care Resource Consumption on Patients with Psoriatic Arthritis or Ankylosing Spondylitis Treated with Biological Drugs in a Northern Italian Region.
Article in Therapeutics and clinical risk management, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeTo analyze the treatment patterns of psoriatic arthritis (PSA) or ankylosing spondylitis (AS) patients under biological therapies and to evaluate in this population the health-care resource consumption and related costs. PATIENTS AND
methodsA retrospective analysis was performed on administrative databases of the Veneto region. Patients ≥18 years with at least one prescription of biological drugs and a diagnosis at any level for PSA or AS from January 1, 2011 to December 31, 2016 (inclusion period) were included. Index date (ID) was defined as date of first biological drug prescription during inclusion period. Patients were characterized the year before ID and followed-up for one year after ID. The drug utilization profile in terms of adherence, persistence and therapeutic regimen changes, and the health-care resource consumption was analyzed during follow-up.
resultsA total of 2602 patients were included: 1857 with PSA and 745 with AS. In the PSA cohort, 40.3% of patients were prescribed adalimumab, 35.6% etanercept, 8.0% golimumab, 7.5% infliximab, 5.6% ustekinumab and 3.0% certolizumab. Percentage of PSA patients adherent to treatment was higher among ustekinumab patients (91.3%) and lower among etanercept users (54.3%). Persistence ranged from 53.2% (infliximab) to 70.3% (etanercept). Regarding AS cohort, 45.5% of patients were prescribed adalimumab, 26% etanercept, 17.3% infliximab, 9.7% golimumab and 1.5% certolizumab. Adherence ranged from 46.9% (etanercept) to 90.9% (certolizumab) and persistence from 62.8% (adalimumab) to 81.8% (certolizumab). Mean annual health-care costs (including costs for drug treatment, diagnostic services, specialist visits and hospital admissions) ranged from €9727 (certolizumab) to €14,994 (ustekinumab) among PSA patients and from €9875 (infliximab) to €12,991 (golimumab) among AS patients.
conclusionThis study in Veneto region gave a picture of biological treatment patterns among PSA and AS patients in a real-world setting. Our findings showed the high degree of variability concerning utilization of each biological drug and provided insight on the economic burden of both diseases.
