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

backgroundThis study investigated recent trends and demographic patterns in tongue cancer surgeries in Japan using nationwide insurance claims data.

methodsAnnual surgery counts and rates (per 100,000 person-years) were analyzed using medical (2014-2022) and dental (2016-2022) claims. Trends were evaluated using linear and Poisson regression to estimate annual risk ratios (RRs).

resultsAn average of 4470.7 surgeries per year was observed (rate: 3.4). The male-to-female ratio was 1.6:1 overall but nearly 1:1 under 40s and over 2.0:1 in the 60s-70s. Surgery rates peaked at ages 75-79 in males (12.0) and 75-84 in females (5.9). Age-adjusted surgery counts rose significantly from 2014 to 2022. Rates increased significantly among all females (RR = 1.020) and overall (RR = 1.010). Significant increases were seen in females aged 40-44 and 60-64 (RR = 1.083 and 1.055).

conclusionsDistinct age- and sex-related trends were identified, particularly rising rates among middle-aged and older females.
