1 · What the graph read from it

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.

2 · The registry

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 AND

aimsMinimally invasive video-assisted thyroidectomy (MIVAT) has been used for the removal of small thyroid nodules to improve cosmetic results and diminish pain. The aim of this study was to compare the outcomes of the MIVAT operations with and without the use of an ultrasonic harmonic scalpel (HS). PATIENTS AND

methodsSeventy-six patients with a solitary thyroid nodule below 30 mm in diameter were randomized to two groups of 38 patients each. Unilateral thyroid lobectomy was performed in each patient. In the clip-ligation group (CL-G), during MIVAT, the superior thyroid vessels were clipped and bipolar coagulation was used to secure smaller vessels, whereas in the harmonic scalpel group (HS-G), HS was used to dissect and divide all the thyroid vessels. The statistical analysis included the mean operative time, blood loss, postoperative morbidity, scar length, cosmetic satisfaction at 1 and 6 months following surgery, and cost-effectiveness.

resultsHS-G vs CL-G operations were shorter (31.4 +/- 7.7 vs 47.5 +/- 13.2 min; p < 0.001), the mean blood loss was smaller (12.9 +/- 5.7 vs 32.8 +/- 13.0 ml; p < 0.001), the mean scar length at 1 month following surgery was shorter (15.6 +/- 1.4 vs 21.5 +/- 1.9 mm; p < 0.001), and greater cosmetic satisfaction was achieved at 1 month after surgery (88.9 +/- 9.7 vs 81.9 +/- 5.4 pts; p < 0.001), but the difference became nonsignificant at 6 months postoperatively. MIVAT with HS was 20-30 euros more expensive. No major complications were observed in both groups.

conclusionsHS in the MIVAT operations is safe and facilitates dissection, allowing for a significant decrease in operative time. Other benefits, such as lower blood loss, a scar a few millimeters shorter, or a slightly better early cosmetic result, are offered at slightly increased costs.
