Hemithyroidectomy versus total thyroidectomy for patients with differentiated thyroid cancer: a systematic review and meta-analysis.
Article in Gland surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: The 2015 American Thyroid Association (ATA) guidelines recommended hemithyroidectomy as an acceptable treatment for patients with differentiated thyroid cancer (DTC) tumors 1-4 cm. The primary objectives of this study were to trace the accumulation of evidence supporting hemithyroidectomy prior to the release of the 2015 ATA guidelines and to synthesize the available data on surgical outcomes for hemithyroidectomy and total thyroidectomy. Methods: PubMed was systematically searched for studies comparing hemithyroidectomy and total thyroidectomy among adult patients with DTC ≥1 cm, focusing on patient outcomes including recurrence rates, overall survival (OS), disease-free survival (DFS), and disease-specific survival (DSS). Fixed-effects or random-effects models were applied as appropriate to estimate risk ratios (RRs) and hazard ratios (HRs) based on the Woolf test. Cumulative meta-analyses were also performed to illustrate changes in pooled estimates as studies were added incrementally by year of publication. Results: The 14 studies, including 176,238 patients, were analyzed. Of these, 88.4% underwent total thyroidectomy and 11.6% (n=20,435) underwent hemithyroidectomy, with a mean follow-up time of 8 years. We found no significant differences between hemithyroidectomy and total thyroidectomy in recurrence rates [RR: 1.036, 95% confidence interval (CI): 0.698-1.538], OS (RR: 0.995; 95% CI: 0.985-1.006), or DSS (RR: 1.001; 95% CI: 0.998-1.005). Total thyroidectomy was associated with marginally better DFS compared to hemithyroidectomy (RR: 0.980, 95% CI: 0.963-0.997). Conclusions: This systematic review and meta-analysis found that total thyroidectomy was associated with slightly greater DFS relative to hemithyroidectomy, but no statistically significant differences were observed in recurrence, OS, and DSS between the two procedures. The accumulation of evidence supporting hemithyroidectomy may have prompted the ATA to revise their guidelines and encouraged surgeons to increasingly consider hemithyroidectomy as a safe procedure for treating patients with DTC ≥1 cm.
