Low rates of pain requiring sacroiliac joint fusion after countersunk iliac screw for spinopelvic fixation.
Article in Journal of craniovertebral junction & spine. 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
Background: Iliac screws (IS) and sacral 2 alar-ISs are common methods for spinopelvic fixation but can result in symptomatic prominence or need for future sacroiliac (SI) joint fusion. A modification of the countersunk ISs technique includes a partial resection of the posterior superior iliac spine (PSIS) and countersinking of the screw head to minimize prominence. We investigate the need for surgical SI joint fusion and pain outcomes following the use of countersunk IS with partial resection of the PSIS. Methods: We identified patients from 2010 to 2024 who underwent spinopelvic fixation with countersunk IS with a minimum of 2 years follow-up. Variables collected included age, sex, body mass index (BMI), smoking status, SI joint fusion, IS site pain, construct infection, skin breakdown, IS revision due to pain or infection, and symptomatic screw prominence. Descriptive statistics were reported. Results: Five hundred and forty-six patients who underwent 1088 IS placements were included. The sample had a mean age of 64.5 years, was 65.3% female, and had a mean BMI of 28.3 kg/m Conclusion: We observed low rates of future surgical SI joint fusion for SI joint pain or reoperations due to IS prominence or screw-related pain with countersunk IS. Future comparative studies are necessary to support these conclusions.
