Predictive Value of Digital Neuropsychological and Gait Assessments on Shunt Outcome in Patients With Idiopathic Normal Pressure Hydrocephalus: Prospective Cohort Study.
Article in Journal of medical Internet research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: The cerebrospinal fluid drainage test is crucial for evaluating patients with idiopathic normal pressure hydrocephalus (iNPH) before shunt surgery, while traditional methods have low sensitivity. Objective: This study aimed to evaluate the improvement of cognitive and gait parameters after external lumbar drainage (ELD) through the application of digital tests and to investigate the predictive value of digital cognitive and gait assessments for shunt outcomes. Methods: A total of 70 patients with probable iNPH were enrolled from the West China Hospital of Sichuan University. All patients underwent traditional and digital cognitive and gait assessments at baseline and 3 days after ELD. Thirty-nine patients received lumboperitoneal shunt and were followed up at 3, 6, and 12 months postoperatively using the modified Rankin scale and the Japanese iNPH grading scales. Firth logistic regression models and receiver operating characteristic analysis were used to assess the predictive value of digital tests for shunt response. Results: The performance of the digital tests, including one-back test (P=.01), the Stroop color-word test (P=.009), and gait parameters, exhibited significant improvement 3 days post-ELD. Of the 39 shunted patients, 34 exhibited at least 1-point improvement in modified Rankin scale or iNPH grading scales postshunt at their last follow-up. Greater improvement rates in combined digital neuropsychological and gait tests after ELD were associated with a lower risk of unfavorable shunt outcome (adjusted odds ratio=0.98; P=.03). Combined digital neuropsychological and gait tests outperformed traditional tests in distinguishing shunt responders (area under receiver operating characteristic curves=0.92 vs 0.55, P=.015). Conclusions: Our study shows that digital neuropsychological and gait tests enhance predictive efficacy when compared to traditional testing methods. It could serve as objective evaluation tools for assessing patients with iNPH.
