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
Background: Postoperative analgesia is of utmost importance in the treatment of patients undergoing surgery. Good postoperative pain management reduces hospital stay and improves early ambulation. This study compared the efficacy of epidural bupivacaine with buprenorphine to butorphanol in lower limb orthopedic surgery. Objectives: This study was carried out to investigate the onset of analgesia, the extent of analgesia, sedation score, and side effects of butorphanol with bupivacaine versus buprenorphine with bupivacaine. Methods: In a clinical trial study, 100 patients who underwent elective orthopedic lower limb surgery were randomly allocated to two groups. A total of 100 patients with American Society of anesthesiologists grades I and II posted for lower limb orthopedic surgery were enrolled in this randomized, double-blind study. The patients were divided into groups A and B. Subarachnoid block was achieved with 3.4 mL of 0.5% bupivacaine. The pain was monitored by the visual analog scale postoperatively. The patients in group A received bupivacaine with buprenorphine, and group B received bupivacaine with butorphanol when they complained of pain in the postoperative period. The onset of analgesia, duration of analgesia, sedation score, and side effects were compared between the two groups. Results: The onset of analgesia was observed earlier in group A than in group B (7.7 ± 1.6 vs. 12.6 ± 1.7 minutes, P < 0.001). The duration of analgesia was longer in group A than in group B (590 ± 40 vs. 480 ± 54 minutes, P < 0.001). Pulse rates and mean arterial pressures were significantly different (P < 0.001). Side effects were common in both groups. Conclusions: Buprenorphine added to bupivacaine provides earlier onset and longer postoperative epidural analgesia than epidural butorphanol with bupivacaine.
