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

purposeThis study aimed to assess the relationship between postoperative blood pressure and other common radiological and epidemiological factors in relation to the incidence of postoperative hemorrhage.

methodsThis retrospective analysis included all patients who underwent surgery between 2016 and 2023 at our institution for an intraparenchymal intracranial tumor. We evaluated blood pressure both intraoperatively and postoperatively for the first 12 postoperative hours. We compared a cohort that experienced postoperative hemorrhage with a cohort that did not require intervention. ROC-analysis were performed to find thresholds for postoperative blood pressure.

results453 patients were included. In 35 cases (7.7%), further treatment was necessary due to postoperative hemorrhage. Of these, nine patients required revision surgery, while 26 patients were managed conservatively. Both intra- (p < 0.05) and postoperative (p < 0.001) blood pressure influenced the risk of postoperative hemorrhage significantly. We identified a threshold of 140 mmHg of systolic blood pressure to minimize the risk of postoperative hemorrhage.

conclusionMaintaining systolic blood pressure below 140 mmHg after surgery seems to be crucial, as patients with postoperative hemorrhage experienced significantly longer durations of elevated systolic pressure (62 min > 140 mmHg and 17 min > 160 mmHg), highlighting its strong influence on hemorrhage risk.
