Early Versus Delayed Cranioplasty After Decompressive Craniectomy: A Systematic Review and Meta-Analysis.
Synthesis in Brain and behavior, 2026. 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
introductionDecompressive craniectomy (DC) is a surgical procedure that involves the removal of a portion of the skull and is used to treat various conditions. However, this creates a significant defect in the skull that requires subsequent reconstruction through a procedure called cranioplasty. Cranioplasty aims to improve cerebral blood flow and enhance neurological functions. The timing of cranioplasty is still a topic of debate and can generally be classified into two categories: "early cranioplasty" and "delayed cranioplasty." To provide evidence-based recommendations for the optimal timing of cranioplasty, our meta-analysis compares the safety and efficacy of early and delayed cranioplasty. METHODOLOGY: An electronic search was conducted on PubMed, Embase, and Cochrane. Multiple reviewers independently screened the studies using Rayyan software, and any conflicts were resolved through mutual discussion. Quality assessment was performed using the Newcastle-Ottawa Scale (NOS). Statistical analysis was carried out using Review Manager version 5.41, with I
resultsEarly cranioplasty was associated with increased risk of overall complications 1.43 (95% CI: 0.81 to 2.53; p = 0.22) and postoperative infections 1.36 (95% CI: 0.36 to 5.11; p = 0.65), shorter operative time -26.76 (95% CI: -41.20 to -12.32; p = 0.0003), and a reduced intraoperative blood loss -21.53 (95% CI: -38.30 to -4.77; p = 0.01). The neurological outcomes, that is, MMSE and GOS scores, favored the delayed cranioplasty or showed no significant difference, respectively.
conclusionThe meta-analysis produced mixed results and required a prospective, multicenter, randomized controlled trial with specified outcome measures to establish a balance between surgical safety and functional recovery.
