Methamphetamine-Associated Pulmonary Arterial Hypertension in a Japanese Pulmonary Hypertension Referral Center.
Article in Circulation reports, 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
Background: Methamphetamine-associated pulmonary arterial hypertension (Meth-PAH) is increasingly recognized in Western countries, but Japanese data remain limited. Methods and Results: Of 363 patients with PAH, we identified 5 patients with Meth-PAH (1.4%); 4 were women, with a mean age of 37.6±7.2 years. Patients receiving PAH-specific therapy showed favorable hemodynamic responses, although 40% of patients experienced treatment discontinuation and methamphetamine reuse. Conclusions: In this case series of 5 Japanese patients with Meth-PAH, there was a high rate of treatment discontinuation and methamphetamine reuse, which suggests possible underdiagnosis of Meth-PAH and barriers to sustained care in Japan.
