1 · What the graph read from it

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.

2 · The registry

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

backgroundReal-world data quantifying the costs of increasing use of biologics in inflammatory bowel disease (IBD) are unknown.

aimTo determine the outpatient IBD drug utilization trends, relative market share, and costs in the USA during a 9-year period.

methodsThe Truven MarketScan

resultsIn 415 405 patients (188 842 CD; 195 183 UC; 31 380 indeterminate colitis; 54.67% female), utilization trends show a consistent rise in the market share of biologics during the 9-year study period. The proportion of patients using biologics increased from 21.8% to 43.8% for CD and 5.1%-16.2% for UC. This contrasts a small decrease in immunomodulator and 5-ASA use for CD and relative constancy of other classes including corticosteroids-only use as primary IBD medication from 2007 to 2015. The average biologic-taking patient accounted for $25 275 PMPY in 2007 and $36 051 PMPY in 2015. The average paediatric biologic-taking patient accounted for $23 616 PMPY in 2007 and $41 109 PMPY in 2015. In all patients, the share of costs for biologics increased from 72.9% in 2007 to 85.7% in 2015 (81.7% in 2007 to 94.9% in 2015 in paediatrics).

conclusionThe vast majority of costs allocated to out-patient IBD medications in the USA is attributed to increasing use of biologic therapies despite the relative minority of biologic-taking patients.
