Comparative study of subdural drain (SDD) versus sub periosteal drain (SPD) in treating patient with chronic subdural hematoma (CSDH).

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
backgroundChronic subdural hematoma (CSDH) is common neurosurgical condition encountered in daily practice. Burr holes evacuation is standard treatment for symptomatic cases. Both subdural drain (SDD) and subperiosteal drain (SPD) have been reported to lower the recurrence rate when used in conjunction with burr holes. A randomized controlled trials were done to see if there were any differences in clinical and radiographic outcomes between the two types of drains.
methodsA total of 42 CSDH patients were enrolled and allocated to one of two groups: SDD (
resultsIn both groups, demographic characteristics such as sex ratio, mean age of patients, concomitant disease, and antithrombotic agent use were similar. At 6 months, 20 (95.2%) and 21 (100%) cases in the SDD and SPD groups, respectively, had a favorable outcome (mRS 0-3). Complete hematoma resolution at 6 months was achieved in 21 (100%) and 19 (90.5%) cases of the SDD and SPD groups, respectively. The amount of drain within 48 h was not difference between the two groups. None of the SDD recurred, but two of the SPD group did, necessitating reoperation, which had no effect on the final outcome.
conclusionThese findings indicate that the drain type (SDD or SPD) has no effect on the outcome. The surgeon's preference determines which procedure is used. Except in symptomatic circumstances, routine postoperative imaging may not be required.
