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: One of the alternatives for lower-limb orthopedic surgery is spinal anesthesia. It can affect the hemodynamic status and cause the prolonged motor and sensory blocks, as well as urinary retention, which are less common in the unilateral technique. Different drugs are used to improve the quality of the block and reduce its complications. Dexmedetomidine, a selective alpha-2 adrenergic receptor agonist, and fentanyl, an opioid medication, could administration as an adjuvant to increase the intrathecal block quality. Hence, this study aimed to compare unilateral spinal anesthesia with bupivacaine/dexmedetomidine (BD) and bupivacaine/fentanyl (BF) regimes on the sensory-motor block among patients with lower-limb orthopedic surgeries. Materials and Method: This randomized, double-blind clinical trial was performed on 36 patients who underwent lower-limb orthopedic surgeries in Qaem Hospital, Mashhad, Iran. The patients were randomly divided into two groups. Patients who received 5.7 mg hyperbaric bupivacaine 0.5% plus 10 μg fentanyl (BF group) or 5 μg dexmedetomidine (BD group) were administered for inducing unilateral spinal anesthesia. Patients and investigators responsible for data collection were not awarded from allocation groups. The sensory-motor block level, duration, postoperative analgesia, and complications were recorded and compared between the two groups. Results: No significant difference was observed between the two groups in hemodynamic changes (i.e., systolic and diastolic blood pressure and heart rate) before and after the blockage (P˃0.05). Also, there was no difference in the sensory-motor block level and anesthesia-related complications between BF and BD groups (P˃0.05). Conclusion: In patients for whom the use of opioids for unilateral spinal anesthesia is contraindicated, dexmedetomidine could be considered an appropriate alternative.
