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
Purpose: Esketamine have anesthetic and analgesic properties. This study aimed to observe the enhancing effect of subanesthetic doses of esketamine (0.15-0.3 mg/kg/h) with dexmedetomidine and remifentanil during anesthesia for liposuction surgery. Patients and Methods: A total of 155 subjects were randomized with a 1:1 ratio to Group E (esketamine-dexmedetomidine/remifentanil, n=78) or Group C (saline-dexmedetomidine/remifentanil group, n=77). The primary outcome was satisfaction of patient and surgical team with the procedure. The secondary outcomes were the postoperative Athens Insomnia Scale (AIS) and Hospital Anxiety and Depression Scale (HADS) scores, hemodynamic and respiratory changes, drug consumption, adverse event rates, and predictors associated with patient satisfaction. Results: Patient and surgical team satisfaction with the procedure was significantly higher in Group E than in Group C (4.7 ± 0.6 vs 4.2 ± 0.7, P < 0.001; 4.7 ± 0.5 vs 4.4 ± 0.7, P = 0.005). The postoperative AIS (4 [1, 6] vs 5 [2, 9], P = 0.012) and HADS-A (1 [0, 3] vs 2 [0, 6], P = 0.012) scores were significantly lower in Group E than in Group C. Hemodynamic and respiratory parameters were more stable in Group E than in Group C, with the lower opioids consumption of sufentanil (0 [0, 4] vs 5 [2.5, 7.7], P < 0.001) and remifentanil (700 [480, 900] vs 800 [500, 1200], P = 0.023) in Group E compared to Group C. On ordinal logistics regression, postoperative sleep quality (OR, 0.70; 95% CI, 0.62-0.79), anxiety level (OR, 0.77; 95% CI, 0.62-0.95) and recovery time in post-anesthesia care unit (PACU) (OR, 0.69; 95% CI, 0.56-0.98) were identified as significant predictors associated with patient satisfaction. Conclusion: A subanesthetic dose of esketamine (0.15-0.3 mg/kg/h) as an adjuvant can improves the sedative and analgesic effects of dexmedetomidine and remifentanil during anesthesia for liposuction surgery.
