Safety of oral mucosal punch biopsy and other oral biospecimen collections in clinical research.
Article in Oral surgery, oral medicine, oral pathology and oral radiology, 2025. 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
objectiveOral punch biopsies are frequently used for analysis of lesions since they are minimally invasive, easily performed, and assist in diagnosis. Despite broad usage, recent changes in risk classification characterize oral punch biopsies as "greater than minimal risk" for institutional review board purposes. We performed a retrospective review of oral sampling in clinical trials to determine the safety of punch biopsies and other biospecimen collection methods in our oral cancer surveillance program. STUDY
designPunch biopsies of 3- and 4-mm were collected following topical and local injection anesthetic. Hemostasis was achieved using pressure and silver nitrate cautery. Other specimens were collected according to standard collection guidelines. Safety and adverse events were determined through consultation with clinical investigator guidelines and were graded with the NCI Common Terminology Criteria for Adverse Events (CTCAE) v5.
resultsIn total, 579 samples were collected, 339 of which were oral punch biopsies. There were no adverse events above NCI CTCAE grade 1 for any biospecimen collection.
conclusionsThese results support the safety profile of oral punch biopsies and saliva collection. Additionally, these results align with previous research on punch biopsy safety and demonstrate fewer bleeding events. Based on the results and prior research, we believe that punch biopsies should be considered a minimal-risk procedure.
