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

purposeTo evaluate whether daily postoperative irrigation combined with suction drainage is associated with improved clinical outcomes compared with suction drainage alone in patients with odontogenic submandibular deep neck abscess.

methodsThis retrospective cohort study included adult patients treated between January 2019 and April 2025. Among 112 screened patients, 60 with odontogenic submandibular abscess larger than 3 cm were included and allocated using an alternating sequence to irrigation plus drainage (Group A, n = 30) or drainage alone (Group B, n = 30). Postoperative daily irrigation with diluted povidone-iodine followed by saline plus suction drainage vs. suction drainage alone. Primary outcomes were length of hospital stay and postoperative complications (reoperation, mediastinitis, or tracheostomy). Secondary outcomes included evolution of inflammatory markers.

resultsBaseline characteristics were comparable between groups. Mean hospital stay was shorter in Group A (5.6 ± 3.4 days) than in Group B (7.5 ± 3.0 days; p < 0.05). Postoperative complications occurred in 10.0% vs. 36.7% of patients, respectively. Irrigation was associated with a reduced risk of complications (risk ratio, 0.27; 95% CI, 0.09-0.79), corresponding to an absolute risk reduction of 26.7% and a number needed to treat of 4. Inflammatory markers declined more rapidly in the irrigation group. Multivariable analysis confirmed irrigation as independently associated with lower complication risk.

conclusionsPostoperative irrigation combined with suction drainage was associated with improved clinical outcomes compared with drainage alone. These findings support irrigation as a potentially valuable adjunct in the management of odontogenic deep neck abscesses.
