Symptomatic and severe pulmonary hypertension due to hyperthyroidism.
Article in BMJ case reports, 2022. 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
Hyperthyroidism has been recognised as the cause of secondary pulmonary hypertension (PH). However, several studies have reported that most PH cases due to hyperthyroidism are asymptomatic and not severe. Here, we report the case of a woman in her 30s with symptomatic and severe PH due to hyperthyroidism. She presented with a 2-month history of dyspnoea on exertion, palpitation and lower-extremity oedema. Echocardiography showed severe PH with estimated pulmonary arterial systolic pressure (ePASP) of 62 mm Hg. The diagnostic work-up showed severe PH due to hyperthyroidism. After treatment for hyperthyroidism, improvement of thyroid function contributed to a decrease in ePASP to 30 mm Hg. Similar to the present case, PH due to hyperthyroidism generally improves with the treatment of hyperthyroidism. Therefore, we must not overlook hyperthyroidism as a cause of PH and diagnose and start treatment for PH-causing hyperthyroidism at an early stage.
