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

backgroundGallbladder polyps are seen in up to 7% of adults and carry a low malignancy risk. Guidelines on indication for surgery and follow-up remain controversial because of regional differences in the development of malignancy. This study compares European practice guidelines for gallbladder polyps and assesses the percentage of patients in whom cholecystectomy was indicated according to the guidelines with a true adenoma postoperatively.

methodsDutch patients with active follow-up or surgery for gallbladder polyps between 2018 and 2020 in 26 participating centres were included. Data on demographics, imaging characteristics, surgery and histopathology were assessed. Indications for cholecystectomy were examined for all patients comparing 2017 and 2022 European guidelines.

resultsA cohort of 302 patients was included. Patients in follow-up underwent imaging three times (median) and were followed up during a median of 23.2 months (IQR 10.9-47.4). In total, 88 patients (29%) underwent cholecystectomy after a median period of 23 months and a median of two instances of imaging. In 71 of 88 patients (81%) who underwent cholecystectomy, the gallbladder polyps was a valid indication for cholecystectomy according to 2017 guidelines, compared to 68 of 88 (77%) according to 2022 guidelines. The difference only occurred due to age as a risk factor which changed from 50 to 60 years of age. Of 71 operated patients, non-neoplastic polyps were found in 49 (69%), no gallbladder wall abnormality was found in 23 (32%). An adenoma was found in six patients (9%), of which three had low grade dysplasia and one had high grade dysplasia. DISCUSSION: Despite revision of guidelines in 2022, a significant number of patients still undergo follow-up and cholecystectomy for non-neoplastic gallbladder polyps, indicating the need for a more comprehensive risk assessment algorithm in the management of gallbladder polyps.
