Blood pressure changes in patients after Minoxidil microinfusion to treat female pattern alopecia: analysis of a randomized, single blinded, placebo controlled clinical trial.
Trial report in Archives of dermatological research, 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
backgroundMicroinfusion is a superficial microneedling procedure that infuses medications into the surface of the dermis through disposable needles attached to tattoo equipment. Various medications can be microinfused; minoxidil is frequently utilized as an adjuvant treatment for androgenetic alopecia, but little data is available on its systemic effects when administered via this technique.
objectiveTo compare blood pressure readings before and after microinfusion of minoxidil in the scalp to assess this drug's systemic effects when applied using this technique.
methodsThis randomized, controlled, blinded study was conducted with 24 patients divided into 2 groups to compare microinfusion with 0.5% minoxidil and saline solution (control group). Participants underwent 3 sessions at monthly intervals, and their blood pressure was measured before and after each microinfusion procedure.
resultsA statistically significant reduction in diastolic blood pressure was observed after the procedure in the minoxidil group (p = 0.037). In the control group, a statistically significant increase in systolic blood pressure was found (p = 0.013).
conclusionReduction of diastolic blood pressure in the minoxidil group proved dermal delivery and systemic absorption of the medication after scalp microinfusion. Increased systolic pressure in the control group may be related to pain during the procedure.
