Effect of Adductor Canal Block Combined with Local Infiltration Analgesia on Postoperative Pain of Knee Arthroscopy Under General Anesthesia: A Randomized Controlled Trial.
Article in Pain and therapy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
introductionPostoperative pain in knee arthroscopy (KA) is a common and troublesome problem. The best local analgesic technique for relieving postoperative pain in patients with KA has not been well studied. This prospective trial aimed to observe whether adductor canal block (ACB) combined with local infiltration analgesia (LIA) could further decrease the incidence of postoperative pain undergoing KA.
methodsThis randomized controlled study recruited 60 patients aged 18-65 years, ASA I-II, who received KA, and randomly divided them into ACB + LIA group and LIA group. The primary outcome was the incidence of postoperative pain 24 h after surgery. The secondary outcomes included the incidence of quadriceps femoris weakness, and the consumption of opioids during operation.
resultsA total of 60 participants completed the trial. The incidence of postoperative pain 24 h after surgery in ACB + LIA group was lower than that in the LIA group (10% [3 of 30] vs. 33% [10 of 30]; P = 0.028). There was no difference in the incidence of quadriceps muscle weakness 24 h after surgery between the two groups. The consumption of remifentanil and sufentanil in ACB + LIA group was significantly lower than that in LIA group (P = 0.006, P < 0.001).
conclusionsCompared with patients receiving LIA alone, ACB combined with LIA could reduce the incidence of postoperative pain while retaining the strength of the quadriceps femoris in patients undergoing KA and reduce the consumption of opioids during surgery.
