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

backgroundProfessional tooth cleaning is a simple, low-cost preoperative oral intervention. Its role in reducing postoperative complications in oral squamous cell carcinoma (OSCC) remains unclear.

methodsThis retrospective cohort study included 415 OSCC patients undergoing radical resection with free flap reconstruction. After propensity score matching, 174 well-matched pairs were analyzed. Patients were divided into a tooth cleaning group (n = 174) and a control group (n = 174). Outcomes included postoperative pneumonia (PP), surgical site infection (SSI), fever, length of stay, and unplanned reoperation were recorded.

resultsPreoperative tooth cleaning was significantly associated with lower PP risk (OR = 0.30). Significant independent risk factors for PP included tumor location at the floor of the mouth (OR = 4.70), hypertension (OR = 2.93), and longer operative duration (OR = 1.33 per hour). The radiographic severity of periodontitis was not a significant risk factor for PP. No associations were found between tooth cleaning and other outcomes. Stratified analyses showed significant protective effects in patients aged > 60 years (OR = 0.19), with hypertension (OR = 0.08), periodontitis (OR = 0.07), or surgeries > 5 h (OR = 0.18).

conclusionPreoperative professional tooth cleaning one day before surgery is associated with a reduced risk of PP in OSCC patients.
