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

objectiveTo evaluate the efficacy of ultrasound-guided thyroid cartilage plane block (TCPB) on postoperative sore throat (POST) in patients undergoing suspension laryngoscopy vocal cord polypectomy (SLVCP).

methodsNinety patients scheduled for elective SLVCP were randomized to either the TCPB group (general anesthesia + ultrasound-guided TCPB) or the C group (conventional GA), with 45 patients in each. The primary outcome was the incidence of POST at 2 h after extubation. Secondary outcomes included the incidence and severity of POST at 0.5, 2, 6, 12, and 24 h after extubation; the incidence and severity of hoarseness at 0.5, 2, 6, 12, and 24 h after extubation; and cough response during emergence.

resultsThe incidence of POST was significantly higher in the C group compared to the TCPB group at 0.5 h (93% vs. 67%, RR = 0.20, 95% CI [0.06-0.64]; P = 0.003), 2 h (78% vs. 47%, RR = 0.42, 95% CI [0.23-0.77]; P = 0.004), and 6 h (64% vs. 27%, RR = 0.49, 95% CI [0.32-0.77]; P = 0.001) after extubation. No significant difference in the incidence and severity of hoarseness between the groups at any time point. During extubation, the incidence of cough response in the C group was 60%, significantly higher than the 20% in the TCPB group (RR = 0.50, 95% CI [0.34-0.74]; P = 0.001).

conclusionUltrasound-guided TCPB significantly reduces the incidence and severity of POST and cough response in SLVCP patients.
