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

purposeThis study evaluated voice and swallowing outcomes following thyroidectomy by using the gasless transaxillary (GTAA) and transoral (TOA) approaches compared with the conventional transcervical approach (CTA).

methodsA comprehensive search of the PubMed, EMBASE, and Cochrane Library databases was conducted through September 2024. Network meta-analyses were performed on 14 comparative studies, encompassing 1723 patients.

resultsVoice handicap index (VHI)-10 scores, highest frequency, and frequency range deteriorated after surgery in all three methods. However, the postoperative voice outcomes of the GTAA and TOA were superior to the conventional approach at all follow-up points up to 3 months after the operation. Specifically, the VHI-10 scores of the GTAA and TOA were significantly lower than those of the CTA at 3 months postoperation. Other acoustic parameters, such as jitter, shimmer, noise-to-harmonic ratio, and intensity range, did not differ among the three methods. The postoperative swallowing impairment score (SIS)-6 of the GTAA and TOA were lower than that of the CTA. Specifically, the SIS-6 of the GTAA was significantly lower than those of the TOA and CTA at 3 months postoperation.

conclusionsThe postoperative voice and swallowing outcomes, especially VHI-10, highest frequency, frequency range, and SIS-6, following remote-access thyroidectomy using the GTAA and TOA were superior to those observed with the conventional approach. Given the limited number of studies included, further research is needed to confirm these findings as new studies emerge, especially those with larger sample sizes, diverse populations, different approaches, and extended follow-up periods.
