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
Minimally Invasive transCervical oEsophagectomy (MICE) is a novel technique with radical lymphadenectomy that avoids a transthoracic access, potentially preserving pleural integrity and obviating one lung ventilation, thereby reducing postoperative pulmonary complications. However, its advantages over conventional Transthoracic Minimally Invasive oEsophagectomy (TMIE) remain unclear. The objective of this study was to assess postoperative outcomes after TMIE and MICE. A retrospective cohort study was conducted including patients with resectable esophageal cancer (cT1-4aN0-3M0) who underwent esophagectomy at the Radboudumc, the Netherlands between 2020 and 2024. The primary outcome was the incidence of postoperative complications within 30 days. Inverse probability of treatment weighting (IPTW) was used to account for confounding between the groups. A total of 115 MICE and 172 TMIE patients were included. After IPTW, overall postoperative complications were more frequent after MICE (60.3% vs. 43.9%, RD: 16.4%, 95% CI: 3.3-29.4). This difference was predominantly driven by a higher incidence of recurrent laryngeal nerve palsy (RLNP) (MICE: 30.4% vs. TMIE: 0.0%). No statistical significant difference was observed in pulmonary complications (18.9% vs. 21.8%, RD: -2.9, 95% CI: -17.1 to 12.5) or anastomotic leakage (5.6% vs. 8.1%, RD: -2.4%, 95% CI: -11.5 to 7.3). Although overall postoperative complication rates were higher after MICE, this difference was mainly attributable to an increased incidence of mostly transient recurrent laryngeal nerve palsy, which is inevitably associated with the transcervical approach. Rates of pneumonia and anastomotic leakage were similar between MICE and TMIE. As these data include cases performed during the early experience with MICE, complication rates may improve as experience accumulates across surgical teams. These findings highlight the need for further evaluation and optimization of the MICE procedure prior to broader implementation.
