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 examine the efficacy of the CTA angiographic point sign in forecasting secondary hematoma expansion following stereotactic surgery in patients with moderate-volume basilar ganglia hematoma and it's potential to enhance postoperative outcomes. Methods: A retrospective analysis was conducted on the clinical data of 143 patients with moderate-volume basal ganglia hematoma (hematoma volume between 30 mL and 60 mL) admitted to the Department of Neurosurgery at Baise People's Hospital from January 2021 to December 2022. Stereotactic surgery guided by the CTA angiographic point sign was conducted in 79 patients (experimental group), while stereotactic surgery guided by the computed tomography (CT) scan was performed in 64 patients (control group). The short-term clinical results (incidence of secondary hematoma expansion, Glasgow Coma Scale (GCS) score within 30 days, death, surgical complications) and long-term clinical outcomes [Modified Rankin Scale (MRS) score after 6 months] were analysed by comparing the two groups. Results: No subsequent hematoma expansion occurrences transpired in the experimental group post-surgery, but 12 (18.75%) such events were observed in the control group following the procedure. The experimental group experienced 27 postoperative lung infections (34.18%), whereas the control group had 33 infections (51.56%). The average GCS score was (9.46 ± 2.23) in the experimental group and (7.94 ± 4.68) in the control group. The mortality rate was 2 (2.53%) in the experimental group and 8 (12.50%) in the control group. The treatment efficacy rate (MRS) at 6 months was 59 cases (74.68%) in the experimental group and 35 cases (54.69%) in the control group. The disparity between the two groups was statistically significant ( Conclusion: CTA angiographic point-guided stereotactic surgery can significantly diminish the incidence of subsequent hematoma expansion following the procedure, enhancing patient clinical outcomes and postoperative quality of life.
