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
backgroundThe effortful swallow (ES) maneuver is widely used in clinical practice, designed to enhance the safety and efficiency of swallowing. Despite its common use in clinical practice, there have been relatively few research studies exploring the impact of effortful swallowing in clinical populations with dysphagia.
objectiveTo evaluate the application of the ES maneuver in post-stroke patients with dysphagia through a structured, protocol-based approach utilizing the Visual Analysis of Swallowing Efficiency and Safety tool (VASES). MATERIALS AND
methodsThis cross-sectional study involved 34 adults with poststroke dysphagia. Each patient underwent a flexible endoscopic evaluation of swallowing (FEES) in the dysphagia clinic of a tertiary care hospital’s phoniatrics unit. An ES maneuver was incorporated into the FEES procedure. The VASES protocol was employed to systematically assess the FEES results. The effect of the ES maneuver was quantified by calculating Cohen’s d for pre- and post-maneuver measurements from the VASE protocol.
resultsLargest residue reductions were found in 10 cc of thin fluids (oropharyngeal: pre-ES d = 1.32, post-ES effect size d = 1.57; hypopharyngeal: pre-ES d = 1.39, and post-ES effect size d = 1.93).
conclusionThe application of an ES maneuver significantly improves pharyngeal clearance and airway protection for larger and more complex bolus volumes.
