Efficacy and safety of 4-hydroxy-2-methyl-N-(5-methyl-2-thiazolyl)-2H-1, 2-benzothiazin-3-carboxamide 1,1-dioxide, a rapid-acting meloxicam formulation, for analgesia after orthopaedic surgery under general anaesthesia: a randomized controlled trial.

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
backgroundPostoperative pain management is one of the most challenging treatments after orthopaedic surgery, and improved medical treatment options are urgently needed. This study aimed to evaluate the efficacy and safety of 4-hydroxy-2-methyl-N-(5-methyl-2-thiazolyl)-2H-1, 2-benzothiazin-3-carboxamide 1,1-dioxide (QP001) for moderate to severe pain following orthopaedic surgery.
methodsThis randomized clinical trial enlisted patients experiencing moderate to severe pain following orthopaedic surgery in 20 hospitals in China. We allocated randomly 132 participants to receive 30 mg QP001 and 66 participants to receive 0.9% saline pre-surgery. The primary efficacy outcome was the total morphine consumption within 24 h.
resultsThe total morphine consumption in the QP001 group, versus placebo group, was significantly lower over the following 24 h [12.53 (10.51) vs. 26.13 (13.98), P < 0.001]. The total morphine consumption in the QP001 group, versus placebo group, was also significantly decreased over the following 48 h (P < 0.001). The QP001 group, versus placebo, showed a significant decrease in the effective pressing times of the analgesic pump, morphine relief analgesia ratio over the 24 h and 48 h periods and the area under the curve for pain intensity-time as well as a significant prolonged in the time of first pressing the analgesic pump and the time of first morphine rescue analgesia (P < 0.001). The QP001 groups, versus placebo, show no significant difference in adverse events, but the incidence of adverse drug reactions decreased (59.4% vs. 75.8%, P = 0.023).
conclusionQP001 provides analgesia and reduces opioid consumption in patients with moderate to severe pain after orthopaedic surgery, with a favorable safety profile.
