Predicting postoperative hypotensive events after posterior spinal fusion for adolescent idiopathic scoliosis.

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
purposeHypotension is the most common cause of delayed postoperative neurologic deficit (DPND). Based on previous findings, a 4-h postoperative intensive blood pressure (BP) monitoring protocol was implemented following posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). This study aimed to determine the effectiveness of the 4-h postoperative intensive BP monitoring protocol as a predictive tool for identifying postoperative hypotensive events.
methodsA case-control study was performed using a prospectively collected dataset of 103 AIS patients who underwent PSF. All patients received 4-h intensive BP monitoring postoperatively before transitioning to standard BP cuff monitoring. Patients who experienced at least one hypotensive event (HE; MAP < 60) were designated as cases, while those with no hypotensive events (NHE) served as controls. Risk factors associated with hypotensive events were then analyzed using t tests and multivariable logistic regression.
resultsThe 4-h postoperative intensive BP monitoring protocol identified 25% of postoperative HEs. The protocol demonstrated a sensitivity of 25%, specificity of 100%, positive predictive value of 100%, and negative predictive value of 88%. Preoperative weight differed significantly between cases and controls (p = 0.02); however, the association did not persist on multivariate analysis. No patients experienced DPND or neurologic deficits.
conclusionThe 4-h monitoring protocol identified 25% of HEs, suggesting limited predictive capacity. the protocol demonstrated a sensitivity of 25%, specificity of 100%, positive predictive value of 100%, and negative predictive value of 88%. Hypotensive events remain difficult to predict, illustrating the importance of frequent blood pressure monitoring postoperatively and quick hypotensive response capabilities.
