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
Background: Trigger finger causes pain and impaired hand function. Ultrasound and paraffin wax are commonly used but have cost and accessibility limitations; cassava wax may be a low-cost alternative, though its effectiveness remains unclear. Objective: To evaluate the immediate, short-term, and post-intervention effects of cassava wax immersion combined with ultrasound therapy on pain, pressure pain threshold, and upper extremity function in patients with trigger finger. Methods: In this single-blind, randomised controlled trial, 38 participants were randomly assigned to two groups ( Results: Both groups showed significant improvements in all outcomes ( Conclusion: Ultrasound therapy combined with cassava wax immersion is more effective than ultrasound therapy alone for managing trigger finger, providing greater pain reduction and improved upper extremity function. Cassava wax may be a valuable, natural, and cost-effective option.
