Use of injections for chronic pain from 2010 to 2019 in Ontario, Canada.

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
purposeThe management of chronic pain often involves interventional procedures such as injections. Nevertheless, there have been concerns raised regarding the frequency with which these injections are being performed. We conducted a descriptive study to examine trends in the use of pain injections over a ten-year time period in Ontario, Canada.
methodsWe used provincial administrative data to conduct a retrospective observational study of the most common pain injections performed from 2010 to 2019 in Ontario. We determined the frequency of pain injections and their associated physician billings from physician billing data.
resultsA total of 18,050,058 pain injections were included in this study with an associated total cost of CAD 865,431,605. There was a threefold increase in the number of blocks performed annually and associated costs, rising from 1,009,324 blocks (CAD 50,026,678) in 2010 to 3,198,679 blocks (CAD 156,809,081) in 2019. The majority of injections were performed by general practioners (70.8%), followed by anesthesiologists (8.3%).
conclusionThis descriptive study revealed a rapid increase in the frequency of pain injections performed in Ontario from 2010 to 2019. Given the associated costs and potential risks, this warrants further investigation to ensure that these interventions are being administered appropriately.
