Chronic postsurgical pain following thyroidectomy: A systematic review and meta-analysis.
Synthesis in Medicine, 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
backgroundChronic postsurgical pain is well recognized after major surgical procedures but often overlooked following thyroidectomy. Given the increasing frequency of this surgery, this systematic review and meta-analysis aimed to synthesize current evidence on the incidence, characteristics, and modulating factors of chronic postsurgical pain after thyroidectomy (CPPT).
methodsA systematic search was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines across 3 electronic databases. Two independent reviewers screened studies for eligibility, extracted data, and assessed methodological quality. Meta-analyses were performed using a random-effects model to estimate pooled incidence rates of CPPT and neuropathic pain. Sensitivity and subgroup analyses were also conducted.
resultsAfter duplicate removal, 241 records were screened, of which 16 studies encompassing 1538 patients met the inclusion criteria. All included studies demonstrated a low risk of bias. The pooled incidence of CPPT at 3 months postoperatively was 18.4%. The pooled incidence of neuropathic pain was 40.9% at 3 months and 9.5% at 6 months postoperatively.
conclusionThe pooled incidence of CPPT was 18.4% at 3 months after thyroidectomy. Neuropathic pain was reported in 40.9% of patients at 3 months and 9.5% at 6 months. Substantial heterogeneity, particularly in the 3-month neuropathic pain estimate, warrants cautious interpretation. These findings highlight CPPT as a clinically relevant but underrecognized complication and support the need for standardized prospective research.
