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
Objective: To evaluate the prognostic impact of surgical margin burden and postoperative management after transoral laser microsurgery (TOLMS) for glottic laryngeal squamous cell carcinoma (LSCC) in a large multicentre cohort. Methods: A retrospective multicentre study included 1216 patients with pT1-pT3 LSCC treated with TOLMS. Surgical margins were classified as free, single superficial positive, multiple superficial positive, or deep positive. Disease-free survival (DFS), disease-specific survival (DSS), and overall survival (OS) were analysed using Kaplan-Meier estimates and multivariable Cox models, accounting for pathological stage and postoperative management. Results: Pathological T category was independently associated with DFS and DSS. A single superficial positive margin showed DFS comparable to free margins. Multiple superficial positive margins were associated with increased recurrence risk, while deep margin involvement was strongly associated with both recurrence (hazard ratio [HR] 3.96) and disease-specific mortality (HR 6.82). Among patients with positive margins, second-look surgery achieved better DFS than postoperative radiotherapy or surveillance. Residual carcinoma at revision surgery was a major predictor of poor DFS and DSS. Conclusions: After TOLMS, oncologic risk is driven by margin type and burden rather than margin positivity alone. Deep margin involvement and residual disease identify patients requiring intensified management, supporting a risk-adapted postoperative strategy.
