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

Objectives: Direct comparisons of functional outcomes between transoral videolaryngoscopic surgery (TOVS) and transoral robotic surgery (TORS) for oropharyngeal cancer remain limited. Methods: This retrospective single-center study included 35 patients who underwent TOVS and 13 who underwent TORS. The European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30, EORTC QLQ-H&N35, and Hyodo scores were assessed preoperatively and at 1, 3, 6, and 12 months. A linear mixed-effects model (LMM) included time, treatment, the group-by-time interaction, T stage (Tis/T1/T2 vs. T3), anatomic subsite (Tonsil vs. not Tonsil), prior cancer-directed treatment, concurrent neck dissection, sex, and age. Results: Both groups showed transient postoperative deterioration followed by recovery. In the prespecified primary longitudinal LMM, treatment had no statistically significant main effect on pain, opening mouth, swallowing, or total Hyodo score. Conclusion: In this cohort, no statistically significant differences in postoperative quality of life or swallowing recovery were detected between TOVS and TORS. This design does not establish functional equivalence; however, TOVS may be a practical transoral option when robotic systems are unavailable. Level of Evidence: 3.
