The prevalence of post-amputation pain in amputees: a systematic review and meta-analysis.
Synthesis in BMC musculoskeletal disorders, 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
objectiveTo systematically estimate the worldwide prevalence of post-amputation pain phenotypes, including phantom limb pain (PLP), residual limb pain (RLP), low back pain (LBP), and contralateral limb pain (CLP), among individuals with limb amputation.
methodsWe searched PubMed, Embase, Web of Science, Chinese Biomedical Database (CBM), China Knowledge Resource Integrated Database (CNKI), and Wanfang Database from inception to 22 February 2026 (PROSPERO ID: CRD420251042011). Observational cross-sectional or cohort studies reporting prevalence data were included. Two reviewers independently screened the records, extracted data, and assessed risk of bias. Meta-analyses of prevalence were conducted using random-effects models in Stata 17.0, with results expressed as pooled prevalence and 95% confidence intervals (CIs).
resultsA total of 51 studies involving 13,053 participants were included. Pooled prevalence estimates were: PLP 61% (95% CI: 56%–65%), RLP 58% (95% CI: 52%–65%), LBP 62% (95% CI: 55%–69%), and CLP 43% (95% CI: 24%–61%). Between-study heterogeneity was high across outcomes (I² > 90%), nevertheless, pooled estimates were generally stable in sensitivity analyses. Funnel plots and Egger’s tests suggested a low likelihood of small-study effects.
conclusionPost-amputation pain is highly prevalent and multidimensional, with LBP emerging as the most frequent phenotype in this review. These findings support comprehensive pain assessment in routine practice, with evaluation of LBP and CLP alongside PLP and RLP to better characterize pain burden and inform individualized management. Given the substantial heterogeneity, pooled estimates should be interpreted cautiously.
