Efficacy of cryotherapy for oral leukoplakia: A systematic review.
Review in Journal of dental sciences, 2026. 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
Oral leukoplakia (OL) is the most common oral potentially malignant disorder and carries a risk of malignant transformation. Cryotherapy is a minimally invasive treatment option for OL, but its efficacy and optimal dose-response remain inconsistent among various studies. This systematic review evaluated the clinical efficacy and safety of cryotherapy for OL lesions and explored whether the characteristics of the lesions and treatment parameters influenced clinical outcomes. Electronic searches were performed in Embase, PubMed, and the Cochrane Central Register of Controlled Trials according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Seven studies reporting original clinical outcomes of cryotherapy for OL lesions were included. Data on cryotherapy dose, number and frequency of sessions, complete regression rates, and recurrence rates were extracted. Seven studies comprised 357 patients and approximately 360 OL lesions. Complete regression rates ranged from 77.8% to 100%. Cryogun cryotherapy needed a mean of 3.1 ± 1.3 treatment sessions to achieve complete regression of the OL lesions, compared to 6.3 sessions by cotton-swab cryotherapy. OL lesions smaller than 2 cm
