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
backgroundEsophagectomy for patients with esophageal cancer is a highly invasive procedure that can lead to substantial postoperative pulmonary impairment. Minimally invasive approaches, such as video-assisted thoracoscopic surgery (VATS) and robot-assisted minimally invasive esophagectomy (RAMIE), have been introduced to improve postoperative outcomes. This study aimed to assess the impact of surgical approach on postoperative pulmonary function recovery.
methodsA retrospective analysis was conducted on patients who underwent esophagectomy between 2006 and 2023. Patients were categorized into three groups: open esophagectomy (OE), VATS, and RAMIE. Pulmonary function was assessed using vital capacity (VC) and forced expiratory volume in one second (FEV1.0) at one, three, six, and 12 months postoperatively. Multivariate logistic regression was performed to identify independent factors influencing respiratory function decline.
resultsIn all approaches, the VC and FEV1.0 decreased at one month postoperatively, followed by gradual recovery. Compared with OE, RAMIE showed a significantly better VC than OE at one month postoperatively (p = 0.04), whereas VATS showed a significantly better FEV1.0 at one month (p = 0.03). By 12 months, respiratory function recovery was comparable among all groups. Postoperative pulmonary complications (PPCs) were identified as a significant risk factor for long-term pulmonary function decline (p = 0.044).
conclusionsMinimally invasive approaches, particularly RAMIE and VATS, contribute to preserving postoperative respiratory function at one month. However, respiratory function recovery is similar across all surgical techniques at one year. Preventing PPCs is crucial for improving respiratory function outcomes. Further prospective studies are needed to validate these findings and refine surgical strategies.
