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
objectivesThe aim of this study was to explore the factors that could predict long term clinical outcomes in SA.
methodsA retrospective study was conducted wherein SA patients undergoing surgical resection with a minimum follow up of 12 months were included in this study. Modified Mccormick Scale (MMS) was utilized to record the neurological status of the patients both preoperatively and at last follow up. Outcomes were assessed as: long term neurological status, that is final MMS grade and neurological deterioration, defined as increase in MMS score as compared to preoperative MMS score. Survival analysis was performed using the kaplan meier curves.
results71 patients were included in this study with mean age of 33.07years. At a mean follow up of 57 months, preoperative MMS was the single independent predictor for moderate-severe neurological deficit (MMS III to V) on multivariate analysis (OR: 30.2, p < 0.001) and had an outstanding AUC of 0.91. Six patients had neurological deterioration at long term follow up. Absence of spasticity (p = 0.028), thoracic-thoracolumbar tumors (p = 0.006), low MMS score (p = 0.01) and hypointense T1 weighted MRI (p = 0.009) were significant predictors of long term neurological deterioration. The median overall survival was 48 months and was significantly higher in low grade tumors (p < 0.001).
conclusionThe study highlights the efficacy of clinical features as a predictor of long term functional outcomes in SA patients. Role of spasticity as a prognostic factor was explored for the first time in this study.
