Stereoelectroencephalography for Epilepsy Presurgical Assessment: A Nationwide Survey of Evolution of Practice in Australia.

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
Background and Objectives: Stereoelectroencephalography (SEEG) is increasingly used worldwide for epilepsy presurgical evaluation. A data-driven view of SEEG practice evolution is lacking for any world region. We aimed to perform a nationwide survey of SEEG use in Australian adult epilepsy centers. We predicted that the proportion of nonlesional MRI cases, number of electrodes, and radiofrequency thermocoagulation (RF-TC) use would increase over time. Methods: All epilepsy centers in Australia undertaking SEEG in patients older than 16 years at any time were invited to participate in a nationwide survey. Data were retrospectively and/or prospectively collected on patient demographics and SEEG exploration. Descriptive statistics were used. Results: A total of 281 SEEG explorations were performed in 8 centers from 2012 until 2023, 278 of which (99%) are reported here. A definite epileptogenic MRI lesion was present in 30.6% with no overall significant growth in the proportion of nonlesional cases (χ² [1, N = 278] = 0.067, Discussion: This comprehensive nationwide and regional survey of SEEG practice comprises full ascertainment of all centers and allows analysis of changes in practice over time. Whole cohort results show a high proportion of nonlesional MRI cases achieving satisfactory surgical outcomes and evolution to increased RF-TC use. Indigenous access to SEEG seems to be lower than expected, consistent with broader health care access issues for this population group. Nationwide collaboration on SEEG data provides a basis for analysis of practice at the individual center and state and national levels to optimize health care planning and sharing of expertise.
