Secondary parkinsonism in a patient of psychogenic polydipsia.
Article in BMJ case reports, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
A 44-year-old man presented with history of slurring of speech, slowness in activities, abnormal posturing of the upper limbs and drooling of saliva from the mouth. He had a 5-yearlong history of compulsive water drinking, consuming 12-15 L of water every day. He was earlier evaluated for the same and found to have low serum sodium (126 mEq/L). Presently, he was admitted at a primary care facility with fever and altered sensorium. He was found to have serum sodium of 94 mEq/L. His sensorium improved with hypertonic saline infusion; however, after a lucid interval of 48 hours, he developed florid extrapyramidal symptoms. Contrast-enhanced MRI brain revealed bilaterally symmetric T2-weighted fluid-attenuated inversion recovery hyperintensity in caudate and lentiform nuclei. A diagnosis of extrapontine myelinolysis with secondary parkinsonism was made. He improved significantly with levodopa therapy.Psychogenic polydipsia is an important cause of hyponatraemia. Overzealous correction of hyponatraemia can be counterproductive.
