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
purposeTo investigate the natural course of motor weakness in cervical radiculopathy and analyze risk factors associated with poor recovery.
methodsA cohort of prospectively enrolled patients presenting with motor weakness due to cervical radiculopathy between March 2024 and March 2025 was retrospectively analyzed. All patients were initially managed conservatively, with surgery reserved for persistent weaknesses or intolerable symptoms. Demographic, clinical, and imaging data were reviewed. Motor strength was assessed using the modified Medical Research Council (mMRC) scale. Patients achieving a motor grade 4 or higher were classified as the recovery group; those who did not were assigned to the non-recovery group. We compared both groups and evaluated possible risk factors for non-recovery.
resultsA total of 52 patients were included; 38 (73.1%) recovered to a motor grade above 4-, while 14 (26.9%) did not. The non-recovery group was significantly older and had more severe initial motor deficits and persistent arm pain. Age was negatively correlated with motor recovery, while higher initial motor grade and arm pain improvement were positive predictors. Univariate logistic regression, penalized regression, and Bayesian analysis identified age, initial motor grade, and arm pain improvement as significant predictors of recovery. Using ROC analysis, we identified thresholds for higher risk of 6-month non-recovery: age ≥ 59 years, initial mMRC ≤ 2, and < 2-point improvement in arm-pain NRS at 2 months.
conclusionMost patients with motor weakness due to cervical radiculopathy recovered functional strength (≥ 4) within 2-3 months of conservative treatment. However, older age, severe initial motor deficits, and persistent pain were associated with a higher risk of incomplete recovery.
