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

Background: Newer analgesic techniques to reduce opioid use and pain after total knee arthroplasty (TKA) include preoperative cryoneurolysis, adductor canal block (ACB), and local anesthetic infiltration between the popliteal artery and capsule of the knee (iPACK) block. The purpose of this study was to evaluate whether changing the regional analgesic from ropivacaine to liposomal bupivacaine would provide superior pain relief and reduce opioid requirements at 2 and 12 weeks following TKA. Methods: We conducted a retrospective medical records review of 140 consecutive patients who underwent primary TKA at a single site and received ACB with ropivacaine (multimodal-ropivacaine [MM-R] group, n=70) or ACB/iPACK with liposomal bupivacaine (multimodal-liposomal bupivacaine [MM-LB] group, n=70). The primary outcomes were the morphine milligram equivalent (MME) of filled opioid prescriptions at discharge and during the first 12 weeks after TKA, as well as the Knee injury and Osteoarthritis Outcome Score and the Patient-Reported Outcomes Measurement Information System pain intensity and pain interference scores at 2 and 12 weeks postsurgery. Results: The median MMEs for discharge opioid prescriptions and all opioid prescriptions were, respectively, 65% ( Conclusion: Compared with ropivacaine-based regional analgesia, liposomal bupivacaine-based regional analgesia in the context of a modern multimodal pain regimen may reduce opioid requirements and improve patient-reported outcomes during acute and short-term recovery after TKA.
