Fear of falling risk after hip surgery in older adults: an updated sex-specific systematic review with GRADE and PAF assessment.
Synthesis in BMC geriatrics, 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
backgroundFear of falling (FOF) is a common clinical issue in elderly individuals, especially after hip fractures. Studies show wide variation in FOF prevalence after fractures, with rates ranging from 38 to 72% and notable differences among study groups. Differences in study design and assessment methods make it necessary to conduct a rigorous systematic review. This will consolidate evidence on both epidemiological patterns and modifiable risk factors for FOF.
methodsA systematic literature search was conducted across nine electronic databases (PubMed, Web of Science, Cochrane Library, Embase, CINAHL, MEDLINE, PsycINFO, CBM, CNKI, VIP, and Wanfang) from inception through January 1, 2025, to identify observational studies investigating the incidence of FOF and associated risk factors in elderly hip fracture patients. Risk of bias assessment was conducted using the Newcastle–Ottawa Scale. Stata 15.0 software was used for meta-analysis, subgroup analysis, and sensitivity analysis in heterogeneity studies. Publication bias was assessed using funnel plots, Egger tests, and Begg tests. We used the population attributable fraction (PAF) and the grading of recommendations, assessment, development, and evaluation (GRADE) evidence assessment to evaluate the quality of the research results.
resultsNine studies involving 3,088 patients from seven countries were included in the meta-analysis. The results indicated that the incidence of FOF was 66.88% (95%CI 0.64–0.70, P < 0.001) in elderly patients with hip fractures, with a higher incidence observed in developing countries (70.61%) and cases using the simplified International Fall Efficacy Scale (67.00%). The incidence of FOF in female patients (71.95%) was significantly higher than that in male patients (53.97%). Those history of falls (OR = 1.98, 95%CI, 1.50–2.24, P < 0.001), postoperative pain (OR = 1.77, 95%CI, 1.03–3.04, P = 0.04), conjunction with other chronic diseases (OR = 1.25, 95%CI, 1.00–1.55, P = 0.05), poor mobility (OR = 1.62, 95%CI, 1.30–2.02, P = 0.001), and anxiety (OR = 1.13, 95%CI, 1.10–1.15, P < 0.001) were identified as risk factors for fear of falling in elderly patients with hip fractures. The results of the evaluation of evidence showed that the history of falls, pain, and anxiety was of high quality. PAF analysis indicated that postoperative pain for 33.99% (95% CI 4.69–63.97%) and anxiety for 8.00% (95% CI 6.54–9.46%) of FOF.
conclusionFOF among older adults remains a substantial global health burden, with notable gendered disparities. If postoperative pain was controlled, approximately one in five FOF could be avoided. Future high-quality longitudinal studies are warranted to refine causal pathways and evaluate the effectiveness of targeted interventions in diverse populations.
