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

STUDY

designThis was a retrospective study to evaluate clinical characteristics of patients who developed symptomatic spinal epidural haematoma (SSEH) after spinal surgery.

objectiveThe objective was to determine clinical parameters associated with the development of SSEH after spinal surgery, and to discuss clinical management and possible preventive measures. Although the incidence rate of SSEH is low, the neurological sequelae are devastating. There are limited reports which identify risk factors for SSEH because of the rarity of the condition.

methodsThe 4,457 cases of spine operations performed in two medical centres were reviewed. Eleven of the cases developed postoperative spinal epidural haematomas, causing neurologic deterioration. The clinical manifestations of these 11 cases were described, and factors associated with the recovery of neurologic function were evaluated.

resultsThe causes of SSEH following spinal surgery included inadequate drainage (9 cases), administration of anticoagulants (6 cases) and complicated coagulation disorders (1 case). The main clinical manifestation was progressive neurological deterioration in the innervated area. Seven cases underwent MRI examination and compressions of dural sac and spinal cord were observed. High pressure haematomas were found in eight cases during haematoma evacuation. Statistical analyses showed that patients with mild nerve injury at the initial stage were associated with better recovery (P<0.05). Patients who recovered completely had shorter symptom duration on average.

conclusionsPost-operative bleeding in the wound and inadequate drainage are the primary causes of SSEH. The severity of neurologic injury before haematoma evacuation was associated with the treatment outcome; therefore, it is important to have early diagnosis of SSEH to prevent progression of the neurologic injury.
