Effectiveness of the cryotherapy spray technique in improving treatment outcomes of plantar warts: A comparative study from Saudi Arabia.
Article in Medicine, 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
Plantar warts are challenging to treat and often recur despite standard therapies. While cryotherapy is effective for their treatment, data on cryotherapy spray techniques are limited, especially in Saudi Arabia. We assessed the efficacy of cryotherapy spray techniques for treating plantar warts, emphasizing cure rates, treatment duration, and side effects. In this single-center comparative before-after study, patients with plantar warts treated using a standardized cryotherapy spray protocol in a dedicated cryotherapy clinic (case group) were compared with a historical control group treated with nonstandardized cryotherapy methods before implementation of the protocol. Control patients were retrospectively identified from medical records and met the same inclusion and exclusion criteria as the case group. We compared cure and recurrence rates, treatment duration, number of treatment sessions, and adverse effects between groups. The standardized cryotherapy spray technique achieved a cure rate of 96.8% and a recurrence rate of 6.5%, compared with 87.9% and 18.2%, respectively, in the control group. Although cure and recurrence rates were numerically more favorable in the case group, these differences were not statistically significant in this small sample. In contrast, the standardized technique was associated with a significantly shorter treatment duration (P = .001), fewer treatment sessions (P < .001), and a lower incidence of pain and erosion (P = .035) than the nonstandardized methods used in the control group. Cryotherapy treatment sessions should be based on the recommended technique in this study, which is a safer, evidence-based method for treating plantar warts, with shorter treatment durations and lower recurrence rates compared to using uncertain cryotherapy methods. Larger, controlled studies are needed to confirm these findings and further define the optimal cryotherapy technique for plantar warts.
