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

purposePost-operative epidural hematoma is a rare but devastating complication of spine surgery. The importance of timely decompression for preserving neurologic function has been repeatedly stressed, but the acceptable timescale for decompression remains controversial. The purpose of this study was to propose a diagnosis and treatment flowchart for post-operative epidural hematoma.

methodsA retrospective chart review from the registry database of 93 patients who underwent epidural hematoma evacuation from January 2007 to December 2021 was conducted. Statistical analysis was performed to assess the correlation between recovery of neurologic function and time to decompression.

resultsSixty patients were included in the statistical analysis. Time to decompression was significantly associated with recovery of neurologic function in the overall analysis and in subgroup analysis of cases of acute post-operative epidural hematoma. As the time to decompression decreases, there is an improvement in the odds of neurological function recovery. Moreover, a critical threshold for the time to decompression was determined to be < 6 h.

conclusionTimely decompression is strongly suggested for post-operative epidural hematoma. We proposed a flowchart as a tool to guide treatment of post-operative epidural hematoma. For acute post-operative epidural hematoma, decompression within 6 h promises better neurologic recovery, and decompression should not be delayed by imaging examination. For delayed post-operative epidural hematoma, decompression should be performed as soon as possible after a definite diagnosis is reached.
