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
introductionTransient or permanent damage to the recurrent laryngeal nerve (RLN) during thyroidectomy is of paramount importance for patient quality of life. The aim of this study is to systematically review the literature concerning the role of the most popular energy-based vessel-sealing devices (LigaSure™ (LS) and Harmonic Scalpel (HS)) in preservation of the RLN during thyroidectomy. The safety and inferiority or superiority of LS and HS compared with conventional haemostatic techniques are highlighted.
methodsA systematic search of the literature was performed. Clinical trials, prospective and retrospective studies that significantly compared the use of LS and HS with conventional haemostasis regarding the postoperative incidence of RLN palsy were included.
findingsThe search resulted in 43 studies, including 17,953 patients treated using energy-based devices or conventional haemostatic methods. Concerning the incidence of RLN palsy, 40 studies showed no significant difference between the energy-based device and conventional groups, whereas two studies demonstrated a significant superiority in performance for LS and HS compared with conventional haemostasis. Only one study exhibited significant inferiority of LS and HS compared with conventional methods. No statistical relationship was observed between energy-based devices and conventional techniques regarding permanent damage to the RLN.
conclusionThe performance of both LS and HS shows no inferiority compared with conventional haemostatic techniques, regarding damage to the laryngeal nerve. Further well-designed studies are needed to investigate their potential benefit in preservation of the RLN.
