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

backgroundHemostasis plays an important role in safe brain tumor resection and also reduces the risk for surgical complications. This study aimed to evaluate the efficacy of FLOSEAL

methodsWe evaluated the hemostatic effect of FLOSEAL by scoring the intensity of bleeding from 1 (mild) to 4 (life threatening). We assessed the rate of success of hemostasis with 100 patients who underwent intracranial tumor resection. We also investigated the duration of the operation, the amount of intra- and postoperative bleeding, the number of hospital stays, and adverse events in patients who used FLOSEAL compared with those who did not use FLOSEAL.

resultsFLOSEAL was applied to a total of 109 bleeding areas in 100 patients. A total of 95 bleeding areas had a score of 1 and 91 (96%) showed successful hemostasis. Thirteen bleeding areas scored 2 and 8 (62%) showed hemostasis with the first application of FLOSEAL. The second application was attempted with five bleeding areas and four showed hemostasis. About 94% (103/109 areas) of bleeding points successfully achieved hemostasis by FLOSEAL. Moreover, FLOSEAL significantly decreased the amount of intraoperative bleeding and postoperative bleeding as assessed with computed tomography on 1 day postoperatively compared with no use of FLOSEAL. There were no adverse events related to FLOSEAL use.

conclusionOur results indicate that FLOSEAL is a reliable, convenient, and safe topical hemostatic agent for intracranial tumor resection.
