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 and aim While the infiltration of surgical incisions with local anesthetics is not a new practice, it remains a crucial component of contemporary multimodal analgesia protocols. This study aimed to evaluate the efficacy and safety of using adjuvants in combination with local anesthetic wound infiltration for pain management in patients undergoing mastectomy surgery. Methods Eighty-one patients aged 18-60 years, classified as American Society of Anesthesiologists (ASA) grade I or II, were scheduled for unilateral mastectomy and randomly assigned to three groups of 27 each. The groups were designated as Group C (bupivacaine alone), Group D (bupivacaine with dexmedetomidine), and Group K (bupivacaine with ketamine). Group C received 0.25% bupivacaine alone, Group D received 0.25% bupivacaine with 1 mcg/kg dexmedetomidine, and Group K received 0.25% bupivacaine with 1 mg/kg ketamine. The time to achieve a Visual Analogue Scale (VAS) score of 3 following local wound infiltration was recorded for each group. Additionally, total postoperative fentanyl intake during the first 24 hours, as measured by the patient-controlled analgesia (PCA) pump, was compared among the groups. Sedation levels were assessed using the Ramsay Sedation Scale (RSS). Data were analyzed using the Chi-Square test and one-way ANOVA in IBM SPSS Statistics for Windows, Version 28.0 (Released 2021; IBM Corp., Armonk, NY, USA). Results Demographic factors were similar across the three groups. Analysis of the VAS scores revealed that the ketamine group provided better postoperative pain control than the dexmedetomidine group (p < 0.001). Groups D (71.72 ± 71.73) and K (3.53 ± 13.42) had significantly lower 24-hour fentanyl intake (in mcg) compared to Group C (the control group), as measured by PCA. Additionally, Group C had a significantly lower RSS at the sixth hour (p = 0.003) compared to both Groups D and K. Conclusion Ketamine, when used as an adjuvant to bupivacaine for local infiltration, enhances the effectiveness and prolongs postoperative analgesia more effectively than dexmedetomidine in patients undergoing mastectomy.
