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

purposeThis study aimed to clarify the true incidence and clinical impact of left vocal cord paralysis (VCP) following total arch replacement (TAR) by implementing routine postoperative laryngoscopic evaluations.

methodsWe retrospectively analyzed 119 patients who underwent TAR at our institution between April 2015 and August 2024. Symptomatic VCP was defined as endoscopically confirmed VCP accompanied by clinical symptoms. All patients underwent routine postoperative laryngoscopic examination. The study endpoints were: (1) the incidence of left symptomatic VCP after TAR, (2) the impact of left symptomatic VCP on postoperative complications, and (3) predictors of left symptomatic VCP.

resultsSymptomatic VCP was observed in 38 patients (31.9%), including 28 with left symptomatic VCP (23.5%). The left symptomatic VCP (+) group had a higher rate of pulmonary complications compared to the left symptomatic VCP (-) group (50.0% vs. 19.8%, p < 0.05) and tended to have longer hospital stays (median 33.5 [21.3-45.3] vs. 23.0 [18.0-35.0] days, p = 0.057). Zone 3 anastomosis was more frequently performed in the left symptomatic VCP (+) group (64.3% vs. 18.7%, p < 0.001). Multivariate logistic regression identified Zone 3 anastomosis as an independent predictor of left symptomatic VCP.

conclusionRoutine laryngoscopy revealed that left symptomatic VCP after TAR is relatively common and might be associated with an increased risk of pulmonary complications. If anatomical and pathological conditions permit, avoidance of distal anastomosis in Zone 3 could help reduce the risk of left symptomatic VCP following TAR.
