1 · What the graph read from it

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.

2 · The registry

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

backgroundVagal schwannomas are well-documented, but cervical sympathetic chain schwannomas (CSCS) are rare, with most knowledge from case reports. This study aims to identify radiological predictors of misdiagnosis and factors guiding surgical approaches based on tumor size and extent.

methodsAn ambispective analysis was conducted on 21 cases of CSCS, examining preoperative data, intraoperative findings and the questionnaire to identify the potential predictors. Tumors were classified into three types based on their relationship with the carotid sheath, and this classification was correlated with vessel ligation and postoperative neural outcomes.

resultsAn excellent agreement was found between radiologist on new classification system(Kappa:0.89). Tumor classification revealed a diverse distribution, with 6 cases identified as Type 1, 6 as Type 2, 5 as Type 3, and 4 as Type 3S. The necessity of external carotid artery (ECA) ligation correlated with the tumor type. Type 3 tumors required ECA ligation in 50% of cases, while Type 1 and Type 2 tumors predominantly involved vascular preservation. Postoperative complications included vagal palsy in 28.5% of cases and first bite syndrome in 71.4%.

conclusionAccurate preoperative planning and a novel staging system can enhance surgical outcomes and reduce postoperative complications as validated by our study.
