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

purposeFine Needle Aspiration Biopsy (FNAB) is a critical diagnostic procedure for head and neck lesions, but its technical complexity poses challenges for beginners. This study aims to evaluate the efficacy and safety of a navigation-guided system (NGS) for ultrasound-guided FNAB compared to conventional methods.

methodsThis was a prospective, non-randomized, comparative study conducted between July 2024 and January 2025. Of 111 patients, 50 were assigned to the NGS group and 61 were assigned to the conventional group. Outcomes assessed included procedure time, number of attempts, first-pass success, complication rate, and non-diagnostic rate.

resultsThe target lesion size was larger in the NGS group compared to the conventional group (2.26 ± 1.46 cm vs. 1.77 ± 0.91 cm, p = 0.042). The in-plane technique was used more frequently in the conventional group than in the NGS group (98.4% vs. 36.0%, p < 0.001). The NGS group demonstrated a significantly shorter procedure time compared to the conventional group (65.27 ± 14.28 s vs. 85.19 ± 22.93 s, p < 0.001). In the NGS group, the procedure time was shorter for the out-of-plane technique than for the in-plane technique (60.99 ± 13.32 s vs. 72.87 ± 13.01 s, p = 0.004). In the NGS group, the procedure time significantly decreased as the number of procedures was accumulated (p = 0.002).

conclusionThe NGS method improves time efficiency in FNAB compared to the conventional method, with this trend being more pronounced in the out-of-plane technique.
