What is the Safe Observation Period for Image-Guided Percutaneous Liver Biopsies?

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
purposeCurrent observation period post-liver biopsy is typically 4 h. This study investigates the safety of reducing the observation period after percutaneous liver biopsy.
methodsPatients who underwent percutaneous liver biopsy between 2017 and 2022 in the Radiology Department of a tertiary centre were included in this retrospective, institutional review board-approved study. Patient demographics, procedure details and complication data were collected from the electronic medical records. Complications were graded according to the Cardiovascular and Interventional Radiological Society of Europe (CIRSE) classification. Conditional survival probabilities were calculated for the 4-h observation period.
resultsAmong 1125 patients, 275 complications were seen; 255 grade 1, 15 grade 2 and five grade 3. Post-procedural pain represented 93% (256) of complications, whereas post-procedural haemorrhage occurred in 17 (6%) patients: 13 were of grade 2 severity requiring prolonged observation, and 4 were of grade 3 severity. Of these grade 3 complications, two required blood transfusion whereas two required embolization. A total of 215 (78%) complications occurred within 1 h, 244 (89%) within 2 h of observation. 16 (94%) of 17 post-procedural haemorrhages occurred within 2 h post-biopsy. If complication-free after 2 h, the probability of experiencing a complication within the next 2 h was 4%.
conclusionThe majority of complications were identified within 2 h of observation. Complications recognised after this period were largely pain-related, with only one grade 3 complication seen (post-procedural haemorrhage).Our findings suggest 2 h of post-procedural observation may be safe. LEVEL OF EVIDENCE: Level 2B, Retrospective Cohort Study.
