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

backgroundInjection of carbon nanoparticle (CN) into the thyroid gland is used to stain CLNs in endoscopic surgery of patients with papillary thyroid cancer (PTC). The black-dye technique facilitates the central lymph nodes (CLNs) harvest and parathyroid protection, but improper handling of CN during injection leads to unwanted staining of surrounding tissues and increases the difficulty in anatomical identification. Therefore, a new method is needed to overcome this problem.

methodsForty-eight patients with PTC underwent endoscopic thyroidectomy via breast approach. Patients were randomized into the indocyanine green (ICG) group (Group ICG; n = 23) and CN group (Group CN; n = 25). After thyroid gland exposure, ICG was injected into the thyroid lobes. Fluorescent CLNs were identified and dissected in Group ICG. In Group CN, CN was used instead. Black dyed CLNs were harvested. The following was compared between groups: demographic characteristics, surgical time, drainage amount, hospital stay duration, number of CLNs harvested, frequency of postoperative hoarseness and hypothyroidism, and surgical cost.

resultsGroup ICG showed decreased hypoparathyroidism frequency than Group CN (1/23 vs. 7/25, p = 0.028) and more harvested CLNs (4.6 ± 1.0 vs. 3.8 ± 1.2, p = 0.020). There was no difference between drainage amount, hospital stay duration, and frequency of postoperative hoarseness. The cost of Group ICG was less than that of Group CN (p = 0).

conclusionInjection of ICG into the thyroid gland using fluorescence imaging in endoscopic surgery in patients with PTC is safer and more effective in identifying CLNs than injection with CN. This novel method can lead to improved identification and subsequent harvesting of CLNs.
