Hemithyroidectomy for low-risk follicular carcinoma of the thyroid: results from a regional hospital.
Article in Singapore medical journal, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionExcellent outcomes after conservative thyroid surgery for low-risk follicular thyroid carcinoma (FTC) have been reported from highly specialised centres. However, it is uncertain whether low-volume hospitals can achieve similar treatment results.
methodsAt our institution, 49 patients with FTC were treated during the period 1991-2014. Patients with minimally invasive FTC (MIFTC) were usually treated with hemithyroidectomy. The demographic data, pathology, treatment modality and oncological outcomes of these patients were retrospectively evaluated.
resultsThe tumours were classified as Stage I in 40.8% of patients, Stage II in 32.7%, Stage III in 20.4% and Stage IV in 6.1%, according to the TNM classification system. Only 4 (8.2%) patients had widely invasive FTC (WIFTC). Vascular invasion or capsular invasion alone occurred in 9 (19.1%) and 19 (40.4%) patients, respectively, while 19 (40.4%) patients had simultaneous vascular and capsular invasions. 34 (69.4%) patients with MIFTC initially underwent hemithyroidectomy, while 15 (30.6%) patients underwent total thyroidectomy. Ten patients who underwent total thyroidectomy received radioactive iodine ablation. The mean follow-up duration was 86.9 ± 56.6 months. There was no disease-specific mortality, although two patients with WIFTC remained alive with disease at the end of the study. The five-, ten- and 15-year overall survival rates were 95%, 91% and 84%, respectively. Five patients from the hemithyroidectomy group died due to other illnesses with no evidence of FTC.
conclusionSatisfactory disease control and excellent survival for MIFTC is achievable by hemithyroidectomy in community hospitals. Total thyroidectomy should be reserved for WIFTC or aggressive tumours with nodal or distant metastasis.
