Effectiveness of tramadol-including multimodal analgesia in spinal surgery: a single-center, retrospective cohort study.
Article in Journal of pharmaceutical health care and sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundMultimodal analgesia (MMA) is recommended for postoperative pain management; however, studies evaluating the effect of tramadol-including MMA on numerical rating scale (NRS)-based postoperative pain levels and the length of stay (LOS) in the hospital are limited. Therefore, this study aimed to compare the before and after effects of tramadol-including MMA application, and assess its effect on postoperative NRS scores and LOS.
methodsPatients who underwent spinal surgery under general anesthesia at the Rakuwakai Marutamachi Hospital in fiscal years 2020 and 2022 were included in this study. The outcomes between the pre- and post-intervention groups were compared through propensity score matching.
resultsFollowing propensity score matching, 249 patients were included in each group. MMA application significantly decreased the median LOS from 10 to 9 days (p < 0.001). Additionally, the median NRS scores exhibited a significant decrease from 4 to 3 on postoperative day (POD) 3 (p = 0.0109) and from 3 to 2 on POD 5 (p = 0.0087). Following MMA application, the number of patients receiving additional analgesics decreased significantly, from 38 to 6 (p < 0.001).
conclusionsThe introduction of tramadol-including MMA can effectively reduce postoperative pain and decrease the LOS for patients undergoing spinal surgery.
