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
Objectives: This study aimed to determine the association between preoperative functional mobility and exceeding the planned length of hospital stay (LOS) after lumbar fusion surgery for lumbar spinal stenosis (LSS) and to identify factors associated with preoperative functional mobility. Methods: A total of 122 patients who underwent lumbar fusion for LSS were included. Preoperative functional mobility was assessed using the Timed Up-and-Go (TUG) test. LOS was categorized as standard (≤14 days) or exceeded (>14 days). Risk ratios (RRs) with 95% confidence intervals (CIs) were estimated using modified Poisson regression to analyze the association between preoperative TUG performance and LOS. Additionally, linear regression was used to identify factors associated with preoperative TUG performance. Results: In the univariate modified Poisson regression model, exceeding the planned LOS was associated with preoperative TUG performance (RR, 1.10; 95% CI, 1.06 to 1.14; P <0.001). In the adjusted model, this association remained significant (RR, 1.10; 95% CI, 1.06 to 1.14; P <0.001). Poorer preoperative TUG performance was also associated with female sex (mean difference, -2.02 s; 95% CI, -3.60 to -0.43; P = 0.014) and psychiatric comorbidities (mean difference, 7.91 s; 95% CI, 1.95 to 13.87; P = 0.010). Conclusions: Poorer preoperative functional mobility is an independent predictor of exceeding the planned LOS after lumbar fusion surgery for LSS. Routine preoperative assessment with the TUG test may help identify high-risk patients, and targeted strategies such as enhanced preoperative and postoperative rehabilitation could reduce the likelihood of prolonged hospitalization.
