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
We aimed to expound the precise application of target-controlled infusion (TCI) of esketamine combined with sufentanil in anesthesia for video-assisted thoracoscopic surgery (VATS) and its effect on hemodynamics, postoperative pain, and safety. Eighty patients scheduled for thoracoscopic procedures were randomly assigned to either a control group [n=40, conventional empiric anesthesia (sufentanil plus propofol)] or an observation group [n=40, TCI of esketamine and sufentanil]. Hemodynamic indices [mean arterial pressure (MAP), heart rate (HR), central venous pressure (CVP), stroke volume (SV), cardiac output (CO), systemic vascular resistance (SVR), and oxygen saturation (SpO2)] were recorded before anesthesia (T0), after induction of anesthesia (T1), 30 min of anesthesia (T2), and at the end of surgery (T3). Recovery profiles [length of stay in the post-anesthesia care unit (PACU), awakening time], Ramsay sedation scores (T0-T3), visual analog scale (VAS) pain scores at 2, 24, and 48 h post-op, and adverse event rates were compared. The observation group showed smaller hemodynamic fluctuations from T1 to T3. At T3, this group had higher MAP, SV, and CO (P<0.05), steadier CVP and SVR, faster recovery (PACU stay and awakening times shorter, P<0.01), lower VAS scores at 24 and 48 h, higher Ramsay scores at T2 and T3, and lower overall adverse event rates (P=0.018) than the control group. TCI of esketamine plus sufentanil improved intraoperative hemodynamic stability, shortened recovery, enhanced early analgesia, and reduced adverse reactions in VATS, supporting its precision and safety.
