The hidden risk: Intracranial hemorrhage following durotomies in spine surgery.
Article in North American Spine Society journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Intracranial hemorrhage (ICH) after durotomy in elective spine surgery, though rare, can pose a significant risk to patient outcomes. Spine surgeries bear a risk of dural tears (DT) with potential of postoperative cerebrospinal fluid leakage (PCSFL). Excessive PCSFL can precipitate a decrease in intracranial pressure, potentially leading to ICH. Literature on ICH as a postoperative complication is scarce. The aim was to assess the incidence and risk factors of ICH in patients undergoing elective spine surgery. Methods: Utilizing the 2020 National Impatient Sample (NIS) adults (>18 years) were selected by primary procedure category codes for spine fusion, discectomy, spinal cord decompression and cervicothoracic/lumbosacral nerve decompression. Exclusion criteria were trauma and malignancy. The primary outcome was occurrence of ICH. Comparative analysis and a multivariable logistic regression were used to identify independent risk. Results: In total, 40,990 patients met our criteria with an incidence of ICH at 0.08%. The ICH-group showed an increased length of stay and higher mortality compared to the control group. Spinal cord decompression, DT and PCSFL were significantly more frequent in patients with ICH. Alcohol, drug abuse and hypertension were significantly more prevalent in patients with ICH. DT, alcohol abuse and hypertension were independent risk factors for ICH. Conclusions: This study underscores the rarity and severity of ICHs following elective spine surgery, emphasizing awareness and looking for possible preventive measures. Our finding suggests that DT, as a complication of surgical techniques, as well as alcohol abuse and hypertension are significant predictors of ICH.
