Decompressive craniectomy in traumatic brain injury: insights from a 15-year multicentre cohort in Sweden.
Article in Scandinavian journal of trauma, resuscitation and emergency medicine, 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
backgroundDecompressive craniectomy (DC) is a last-resort treatment for severe traumatic brain injury (TBI) with refractory intracranial hypertension. Randomized controlled trials (RCTs) report mixed and sometimes conflicting results, leaving uncertainties regarding indications, timing, and long-term benefits. This study explored DC practices and outcomes in a contemporary Swedish setting contextualised in modern RCT evidence.
methodsThis retrospective multicentre study included 299 TBI patients who underwent DC between 2008 and 2022 across four Swedish neurosurgical centres. Clinical, radiological, surgical, and outcome data (6-months Glasgow Outcome Scale) were collected. Differences across centres and between adults/children were analysed.
resultsAnnual DC rate remained stable over 15 years, modestly declining from 3.6 to 3.2 per million inhabitants. Significant regional differences were observed in timing, indications, and techniques. Proportion of primary versus secondary DC and surgery timing remained unchanged, though bifrontal DC decreased. Patients were young (median age 37), predominantly male (76%), severely injured (GCS M < 6), and 48% had unreactive pupils. Radiological improvement in mass effect post-DC (midline shift, basal cisterns) was significant (p < 0.001). Re-operation for haemorrhage occurred in 10%, complementary decompression, surgical-site infection, and subdural hygroma each occurred in ~ 5%. At 6 months, 60% had unfavourable outcomes and 11% were deceased. Higher age, lower GCS, comorbidities, impaired pupillary reactivity and obliterated basal cisterns independently predicted unfavourable outcome.
conclusionsLandmark RCTs appear to have had limited influence on Swedish DC practice, which remains variable across centres. Real-world outcomes were more favourable than in recent RCTs and other acute brain injuries.
