Early Percutaneous Cryoneurolysis for Pain Control After Rib Fracture for Older Patients: A Prospective Randomized Clinical Trial.
Trial report in Journal of the American College of Surgeons, 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
backgroundRib fractures are common and multimodal pain control bundles are essential to optimal care. Minimizing therapeutic side effects is important among older adults. The purpose of this study is to determine whether the addition of CT-guided percutaneous cryoneurolysis (CT-PCN) to existing multimodal pain control bundles reduces pain associated with rib fractures in older adults. STUDY
designA prospective, randomized clinical trial assessed the addition of CT-PCN to a multimodal rib fracture pain control bundle (standard of care [SoC]) for injured adults aged 65 years or older. Bluntly injured patients with fractured ribs 3 to 9 were randomized 72 hours or less from admission to CT-PCN and SoC, or SoC alone. The primary outcome was the highest pain score within 24 hours of discharge with deep inspiration. Secondary outcomes included hospital length of stay, rib-specific readmissions, intervention-associated adverse events, morphine milligram equivalent use, 12-item short form, and McGill pain scores, assessed at discharge and at 1-, 3-, and 12-month intervals postdischarge.
results110 patients were included (56 in the intervention group, 54 in the SoC group). No difference in highest pain score with deep inspiration (intervention mean 5.6 [SD 2.4] vs SoC mean 5.9 [SD 2.4]; p = 0.49) was within 24 hours of discharge between groups and there was no difference in milligram equivalent use on day of discharge (intervention median 24 [IQR 6 to 45] vs SoC median 15 [IQR 4 to 34]; p = 0.29). Among 77 participants completing a 1-month follow-up (39 in the intervention group, 38 in the SoC group), the mean numeric pain score was 1 point worse among intervention patients (intervention mean 2.7 [SD 2.4] vs SoC mean 1.7 [SD 1.8]; p = 0.04), and the mean sensory pain score was 3.1 points higher (95% CI 1.4 to 4.9; p < 0.001).
conclusionsCT-PCN did not decrease pain associated with rib fractures and may be associated with worse physical quality and emotional response to pain within 1 month after hospital discharge.
