Analysis of clinical characteristics and risk factors on serrated polyps with synchronous advanced adenoma in elderly and non-elderly people: a retrospective cohort study.
Article in BMJ open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
objectivesSerrated polyps (SPs) with synchronous advanced adenoma (AA) may increase the incidence of colorectal cancer. However, current studies do not address this combination of SPs and AAs in detail with regard to their clinical characteristics in different age groups. The aim was to assess clinical characteristics and risk factors for SPs with synchronous AA in different age groups.
designRetrospective cohort study.
settingElectronic medical record data from January 2011 to January 2022 at three grade III class A hospitals were enrolled in the study.
participantsA total of 1605 patients with SPs with synchronous AA, including 484 patients in the elderly group and 1121 patients in the non-elderly group, were studied. MAIN EXPOSURE MEASURE: The elderly group and the non-elderly group.
main outcome measureSex, smoking history, drinking history, body mass index (BMI), SP location, size, morphology and pathology.
resultsThe incidence of hyperplastic polyps (HPs) with synchronous AA in the elderly group was higher than that in the non-elderly group, while the incidence of sessile serrated adenomas/polyps (SSAs/Ps) with synchronous AA in the non-elderly group was higher than that in the elderly group. Male sex, drinking history and HP size (≤20 mm) were independent risk factors for HPs with synchronous AA in the non-elderly group, while drinking history and HP size (≤15 mm) were independent risk factors in the elderly group. For SSAs/Ps with synchronous AA, male sex, smoking history, drinking history, and SSA size (≥16 mm) were independent risk factors in the non-elderly group; high BMI was an independent risk factor in the elderly group.
conclusionsSPs with synchronous AA showed different clinical characteristics and risk factors in different age groups.
