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

backgroundNon-robotic transoral surgery (NRTOS) is the mainstream approach for pharyngolaryngeal cancer resection in Japan, whereas the da Vinci surgical system is not widely used. NRTOS employs reusable instruments, resulting in significantly lower costs than those of transoral robotic surgery (TORS). Given the comparable oncological outcomes, this study aimed to investigate the risk factors for complications and mortality following NRTOS as an alternative to TORS. PATIENTS AND

methodsThis retrospective cohort study utilized Japanese claims data from diagnosis procedure combination and receipt databases. Data from patients who underwent NRTOS between April 2020 and December 2022 were collected. The primary outcomes were postoperative bleeding, dysphagia, and laryngopharyngeal edema.

resultsAmong the 336 included patients, 88.7% were male, with a median age of 72 years. The incidence rates of bleeding, dysphagia, and laryngopharyngeal edema after NRTOS were 3.3%, 4.2%, and 8.0%, respectively. Univariate logistic regression analysis revealed that history of hypertension [odds ratio (OR): 9.82, 95% confidence interval (CI): 1.24-77.50] was a possible risk factor for postoperative bleeding, while a disease stage ≥ T2 (OR: 5.37, 95% CI: 1.52-19.00), a body mass index < 18.5 kg/m

conclusionsNRTOS demonstrated relatively low complication and mortality rates, establishing it as a safe technique for pharyngolaryngeal cancer resection.
