A Case of Hypotonia-Cystinuria Syndrome With Genito-Urinary Malformations and Extrarenal Involvement.
Article in Frontiers in pediatrics, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Hypotonia-Cystinuria syndrome (HCS) is a rare disease, caused by a mutation in two contiguous genes (SLC3A1 and PREPL) localized on chromosome 2p21, and it is characterized by both renal involvement with cystine stones and nervous involvement with hypotonia. We here describe a 2 years old child with HCS associated with other clinical features as congenital anomalies of kidney and urinary tract (primary obstructed megaureter, POM), cryptorchidism and cardiac involvement (patent foramen ovale with atrial septum aneurysm). To the best of our knowledge, cryporchidism and POM have never been reported before in patients with HCS. Moreover, a cardiac involvement has been described only in another case of HCS that, interestingly, presents the same genetic abnormalities as our patient. The diagnosis of HCS can be difficult because neurological signs are aspecific and kidney stones are commonly absent during the first months of life. A better understanding of the complete clinical scenario associated with HCS can help clinicians suspect, diagnose and treat HCS earlier with a positive influence on both neurological and renal outcome.
