Surgical Interventions in Idiopathic Intracranial Hypertension-A Comprehensive Multi-Center Study of Outcome and the Role of Treatment Indication.
Observational study in European journal of neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundSurgical intervention is recommended in idiopathic intracranial hypertension (IIH) for fulminant or treatment-refractory cases, yet data on outcomes remain limited, particularly regarding indication-specific effects. This study evaluated outcomes and indications for surgery in IIH, aiming to identify predictors of favorable or adverse results.
methodsA retrospective multi-center study was conducted by the Danish-Austrian IIH Consortium (DASH-IIH). Databases from three centers (Vienna, Odense, Copenhagen) were screened for persons with IIH (pwIIH) fulfilling revised Friedman criteria who underwent surgery and had ≥ 6 months of follow-up. Outcomes at 6 months included visual function, headache improvement (≥ 50%), papilledema resolution, and severe adverse events. Multivariable regression was used to adjust for confounders.
resultsOf 1310 pwIIH, only 3.6% required surgery overall. Thirty-six pwIIH were included (100% female; mean age 32.5 years; median BMI 37.0; median CSF opening pressure 41 cmH
conclusionCSF diversion and ONSF are effective in IIH with acute visual threat, improving vision and, to a much lesser extent, headache. Refractory headache alone appears insufficient indication for surgical intervention.
