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 Aims: This study evaluates the analgesic efficacy of ketamine and dexmedetomidine as an adjuvant with ropivacaine 0.2% in pectoral nerve type II block (PECS-II) in modified radical mastectomy. The primary outcome of the study was the time to first rescue analgesia postoperatively. The secondary outcomes were intraoperative and postoperative opioid consumption and postoperative pain on the numerical rating scale. Material and Methods: Seventy-five adult female patients who underwent a modified radical mastectomy participated in this prospective, randomized, double-blinded clinical trial. The patients received 30 ml of 0.2% ropivacaine with or without adjuvants by the ultrasound-guided PECS-II block. Group R ( Results: Duration of analgesia determined by time to first rescue analgesia was longer in group RD (18.42 ± 02.15 h) compared to group RK (15.91 ± 03.21 h) and group R (14.64 ± 02.85 h), which was statistically significant ( Conclusion: We conclude that dexmedetomidine with 0.2% ropivacaine in the PECS-II block provides better postoperative analgesia and has less sedative effects than ketamine with 0.2% ropivacaine.
