What is the postoperative prognosis of proximal humeral fractures in China? Protocol for a multicentre prospective cohort study (CAST).
Article in BMJ open, 2025. 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
introductionProximal humeral fractures are increasingly common, particularly among older people, whereas the prognosis of surgical treatments for these fractures remains substantially uncertain. In China, where the ageing population is rapidly growing, high-quality prospective data on surgical outcomes, complications and cost-effectiveness are lacking. To address this gap, we propose to initiate a prospective, multicentre cohort study on surgical treatment for proximal humeral fractures in China-Cohort of Acute Shoulder Trauma (CAST) study. METHODS AND ANALYSIS: The CAST is a multicentre, prospective cohort study enrolling patients with acute proximal humeral fractures undergoing surgical treatments at eight hospitals in China between May 2024 and December 2029. Patients can receive any of the surgical treatment methods which include percutaneous Kirschner wire fixation, external fixation, open reduction and internal fixation using locking plates or intramedullary nails, suture anchors and shoulder arthroplasty. We will collect patient-reported outcome measures (Quick Disabilities of the Arm, Shoulder and Hand), Constant-Murley, American Shoulder and Elbow Surgeons, EuroQol 5-Dimension and Visual Analogue Scale), physical examination results, imaging assessments (based on X-rays, ultrasound, CT and MRI scans), laboratory tests (including inflammatory cytokines) and data on medical costs. We will follow patients at 1 day, and at 1 month, 3 months, 6 months, 12 months and 24 months postoperatively. The planned sample size is 1500 patients. ETHICS AND DISSEMINATION: The study protocol has been approved by the Ethics Committee of Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University (Approval No. 2024-ky-104(K)). Written informed consent will be obtained from all participants. Findings from the CAST study will be disseminated through peer-reviewed journals and academic conferences. STUDY REGISTRATION NUMBER: ChiCTR2500109651.
