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

purposeDifferences in the suppression of withdrawal symptoms have been observed in opioid-use-disorder (OUD) patients who were switched from Suboxone (the brand name of buprenorphine/naloxone sublingual films) to either 1 of 2 generic versions. These descriptive observations evidence the need to further assess the use of these generics and its impact on the adherence to and outcomes of OUD treatments. The objective of this case series was to describe patient and provider experiences, perceptions, and preferences when said patients were abruptly switched from Suboxone to one of the generic versions manufactured by Sandoz or Alvogen. PATIENTS AND

methodsA retrospective chart review of 24 Suboxone-maintained OUD patients from a single clinic who were forced to switch to a generic was performed to collect withdrawal and craving symptoms that occurred after the switch, as well as toxicology results and changes in dose (documented by the provider).

resultsThe medical records of 9 (37.5%) of the 24 patients showed that they were suffering from withdrawal symptoms and/or cravings, had had their doses adjusted, and/or had had a positive urine toxicology screen. All 9 subjects communicated a preference for the brand formulation over that of either of the generic versions; few expressed a preference for one generic formulation over the other. None of patients were able to switch back to the brand formulation, nor were any of them able to choose the generic that worked best for them. Insomnia, muscle pain, and gooseflesh skin were the most common withdrawal symptoms reported by the patients using the generics. Better outcomes were observed in patients who received a buprenorphine dose increase (2 mg) to suppress the withdrawal symptoms experienced while using the generics.

conclusionOur study serves as a reference to prescribers regarding approaches (eg, a small dose adjustment) that may potentially encourage OUD treatment adherence and even improve outcomes in patients who appear to be decompensating after the brand-to-generic switch.
