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

backgroundMarijuana use disorder (MUD) is the most common illegal drug use disorder and its prevalence is increasing. It is associated with psychiatric and medical problems, but little is known about its impact on emergency department (ED) and inpatient utilization rates.

designIn a retrospective cohort design, we used electronic health record (EHR) data to identify patients with MUD (n=2752) and demographically matched patients without MUD (n=2752) in 2010. Logistic regressions determined risk of ED and inpatient visits each year from 2010 to 2014 for MUD patients versus controls; mixed-effect growth models examined differences in utilization rates over 5-years. Patient characteristics predicting increased risk of utilization were examined among the MUD sample only. KEY

resultsRates of ED (OR=0.87, p<0.001) and inpatient (OR=0.76, p<0.001) services use significantly declined over 5 years for all patients. Patients with MUD exhibited a significantly greater decline in ED (OR=0.81, p<0.001) and inpatient (OR=0.64, p<0.001) use relative to controls. However, MUD patients had significantly greater risk of having ED and inpatient visits at each time point (p's<0.001). MUD patients with co-occurring other substance use, medical, and/or psychiatric disorders had a greater risk of having ED or inpatient encounters over 5 years (p's<0.001).

conclusionsMUD patients remain at high risk for ED and inpatient visits despite decreasing utilization rates over 5 years. Addressing MUD patients' comorbid conditions in outpatient settings may help reduce inappropriate service use.
