Postoperative drain after transoral endoscopic thyroidectomy vestibular approach (TOETVA) with single incision.
Trial report in Surgical endoscopy, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
objectiveTo find the optimal size of a drain for the reliable drainage and the best cosmetic result in TOETVA. To explore the normal drainage flow rate after TOETVA.
methodsA prospective randomized controlled trial was performed in a single center from December 2016 to December 2018. One hundred and fifty-three (153) patients had TOETVA with a single incision and were randomly divided into two groups. Self-made drainage tubes with a small diameter (outer diameter 2.0 mm, inner diameter 1.0 mm) were used in 80 patients (experimental group). No. 8 tubes were used in 73 patients (control group). The clinical characteristics and results between both groups were compared by t test or chi-square test, and the results of normal drainage flow rate were calculated.
resultsThe experimental group had a longer intraoperative tube-inserting time, compared with the control group (9.5 ± 2.5 min vs. 5.6 ± 1.4 min, p = 0.001), a smaller scar six months after the operation (1.8 ± 2.3 mm vs. 3.1 ± 2.6 mm, p = 0.002), and a lower Vancouver Scar Scale score at both one month (3.20 ± 1.44 vs. 4.19 ± 1.92, p = 0.001) and six months after the operation(1.43 ± 1.84 vs. 2.40 ± 2.37, p = 0.006). The drainage volume, pain score on the first day, postoperative complications (tube blockage, air leakage, subcutaneous hydrops, hematoma, regional infection), and the extubation time were not significantly different. The average drainage of 148 patients without postoperative complications was 78.3 ± 10.9 ml. The cumulative drainage within 8 h, and 32 h after the operation accounted for 53.2% and 91.9% of the total drainage, respectively. The residual drainage at 32 h was estimated to be 6.5 ± 2.9 ml (P95 = 11.0 ml). A linear regression equation between total volume (V
conclusionIn TOETVA, a small drain can provide a good cosmetic appearance and reliable drainage. The main exudation period of the wound is within 8 h after the operation. If a residual volume of less than 11 ml is considered to be self-absorbable, the shortest safe extubation point for 95% of patients should be 32 h after the operation.
