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
Objective: To compare the efficacy of exhaustive and fixed-time drainage for chronic subdural hematoma (CSHD) after burr hole craniostomy (BCT). Methodology: This single-center retrospective case-control study included 140 patients with CSHD who underwent BCT at the Third People's Hospital of Yancheng City from December 2021 to April 2024. According to the surgical records, 69 patients underwent fixed-time drainage, which was removed after 48 hours (control group) and 71 patients underwent postoperative exhaustive drainage (observation group). The primary outcomes of interest included surgical efficacy and recurrence rate at six months after surgery. The secondary outcomes were Markwalder's Grading Scale and Glasgow Coma Scale (MGS-GCS), modified Rankin scale (mRS) score and incidence of complications. Results: Six months after surgery, the total efficacy of the observation group (91.5%) was significantly higher than that of the control group (79.7%), while the recurrence rate was significantly lower (4.2% vs. 14.5% in the control group) (P<0.05). The MGS-GCS grading of both groups improved compared to preoperative levels and was significantly better in the observation group than the control group (P<0.05). Intervention led to a decrease in the mRS scores of both groups. The post-intervention mRS scores in the observation group were considerably lower than in the control group (P<0.05). The incidence of complications in the observation group (9.9%) was lower than that in the control group (20.3%), but the difference was not statistically significant (P>0.05). Conclusions: Compared with fixed-time drainage, exhaustive drainage of CSDH after BCT can improve surgical efficacy and reduce the recurrence rate. Further multi-center randomized controlled trials are still needed to confirm the results.
