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
objectiveTo evaluate the effects of dexmedetomidine combined with propofol versus propofol alone on intraoperative hemodynamic stability and postoperative recovery in elderly patients undergoing thoracoscopic lung cancer resection.
methodsThis retrospective comparative study included 123 patients aged ≥ 65 years scheduled for thoracoscopic lung cancer resection. Patients were divided into two groups: the dexmedetomidine-propofol group (observation group, n = 61) and the propofol-only group (control group, n = 62). Hemodynamic parameters - heart rate (HR), mean arterial pressure (MAP), systolic blood pressure (SBP), and diastolic blood pressure (DBP) - were recorded at predefined time points. Postoperative recovery times, stress and inflammatory markers (tumor necrosis factor-alpha [TNF-α], interleukin-6 [IL-6]), adverse events, sedation scores, and pain scores were assessed. Multivariable regression and subgroup analyses were conducted to identify independent treatment effects and explore heterogeneity across patient subgroups.
resultsThe observation group demonstrated significantly more stable hemodynamic profiles, with lower HR, MAP, SBP, and DBP fluctuations across time points (all P < 0.05). Postoperative awakening and orientation recovery times were significantly shorter in the observation group (both P < 0.05). Levels of norepinephrine, epinephrine, TNF-α, and IL-6 were significantly lower postoperatively in the observation group (all P < 0.05). Incidences of respiratory depression and nausea/vomiting were also reduced (all P < 0.05). Multivariable analysis confirmed the independent benefit of the combined regimen. Subgroup analyses revealed greater efficacy in patients with ASA class II and those over 75 years of age.
conclusionThe combination of dexmedetomidine and propofol enhances intraoperative hemodynamic stability, accelerates recovery, reduces perioperative stress and inflammation, and lowers the incidence of adverse events in elderly patients undergoing thoracoscopic lung cancer resection. These results support its clinical value, particularly in high-risk subpopulations. Further studies are needed to refine dosing strategies and optimize safety.
