Chronic Subdural Hematoma: Predicting Postoperative Recurrence Using a Correlation of Computerized Tomographic Volume with Intraoperative Volume.

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.
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
Background: Chronic subdural hematoma (CSDH) recurrence is the most common complication following surgery. Objective: To predict postoperative recurrence of CSDH using a correlation of the calculated preoperative brain computerized tomographic (CT) volume with the intraoperative volume. Materials and Methods: A prospective study was conducted over 14 months in a tertiary hospital in southwestern Nigeria. History with focused examination findings and patient grading using Markwalder classification were documented preoperatively. Preoperative CSDH CT volume was documented and compared with the intraoperative volume. Patients were followed up clinically for features of recurrence at 1, 3, and 6 months postoperatively, and repeat brain CT was done when recurrence was suspected clinically. Results: Forty-seven out of 51 patients recruited completed the study, and four were lost to follow-up. Thirty-three (70.2%) were males, and the average age was 51.4 years. Most of the patients were in the 5th and 7th decades of life. Three patients had recurrence (6.5%), and one patient died (2.1%). Trauma was the most common cause of CSDH (35 out of 47 [74.5%]), spontaneous in 11 (23.4%), and anticoagulant related in 1 (2.1%) patient. Most patients (37/47; 78.7%) presented with headache. The mean brain CT volume and intraoperative volume of CSDH were 102.58 ± 54.13 and 87.74 ± 46.6 mL, respectively, with no significant difference between them ( Conclusion: The calculated preoperative CT volume had a positive linear correlation with intraoperative volume. Intraoperative CSDH volume >130 mL was associated with an increased risk of recurrence.
