1 · What the graph read from it

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.

2 · The registry

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

purposeThe relationship between preoperative blood pressure (BP) and intraoperative mean arterial pressure (MAP) and estimated blood loss (EBL) in pediatric spine surgery is currently unknown. The objectives of this study were to determine if elevated preoperative BP is associated with elevated intraoperative MAP, EBL, and percentage estimated blood volume (EBV) lost, and to determine if intraoperative MAP is associated with percentage of EBV lost during posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS).

methodsThis is a retrospective cohort analysis of 209 patients undergoing PSF for AIS between 2016 and 2019 by a single surgeon. Data extracted included demographic characteristics, preoperative systolic and diastolic BP, continuous intraoperative MAP measured by arterial line, EBL, radiographic, and surgical characteristics. Time points of interest for MAP included incision and exposure. Elevated BP was defined as > 1 standard deviation above the mean BP of patients included in the study, and elevated MAP was defined as > 65 mmHg.

resultsElevated preoperative systolic BP was associated with elevated MAP at incision (p = 0.002). Patients with elevated preoperative diastolic BP had significantly higher MAP at exposure and throughout the procedure (p = 0.04). MAP > 65 at incision was associated with a 5% increase in EBV lost (p < 0.001).

conclusionsPatients with elevated preoperative BP parameters have increased MAPs at incision, exposure, and throughout surgery. Elevated MAP at incision is associated with an increased percentage of EBV lost in a small number of patients undergoing PSF for AIS.
