The Impact of Etiology on Time to Vocal Fold Motion Recovery in Unilateral Vocal Fold Paralysis.

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
objectivesSpontaneous recovery of vocal fold (VF) motion in unilateral vocal fold paralysis (UVFP) has been shown to follow a bimodal time distribution for peripheral, nonidiopathic etiologies, but recovery time dependencies on UVFP etiology are incompletely characterized. This study aimed to (1) determine recovery time differences between surgically induced, idiopathic, and intubation-related UVFP, and (2) investigate the impact of distance of injury from larynx on recovery time in surgically induced UVFP.
methodsRetrospective study of 1425 UVFP patients over a 16-year period identified 736 patients with recovery of VF motion. The time to the first laryngoscopic sign of VF motion recovery in surgically induced, idiopathic, or intubation-related UVFP was fit to a bimodal or unimodal mathematical model. Time course of VF motion recovery was also compared using Kaplan-Meier estimates.
resultsSurgically induced UVFP demonstrated a bimodal time-to-recovery distribution, consistent with a previously described two-phase model of recovery. Both idiopathic and intubation-related UVFP followed unimodal recovery patterns. Among surgically induced cases, Kaplan-Meier recovery curves for thyroid/parathyroid and cardiothoracic surgeries were nearly identical despite differing injury locations along the recurrent laryngeal nerve.
conclusionDifferences in the time course of VF motion recovery in UVFP reflect the underlying etiologies. Among surgically induced UVFP, the recovery time did not correlate with the distance between the injury site and the larynx, challenging a long-held assumption. The findings support a model in which the severity of neural injury, not the location of injury, is the principal determinant of time to recovery. LEVEL OF EVIDENCE: 3:
