Hyperparathyroidism in hepatobiliary disease in infancy.
Article in European journal of pediatrics, 1975. 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
Metabolism of calcium and magnesium may be disturbed in hepatobiliary disease because of deficient or absent bile flow into the gut, since bile is important for the intestinal absorption of these elements. In the present paper the tubular reabsorption of phosphate (TRP), calcium (TRCa), and magnesium (TRMg) were determined in an attempt to evaluate the parathyroid function of infants and children with hepatobiliary disease. In unrepaired biliary atresia TRP was conspicuously reduced (mean 49.8%, SD 15.1). In successfully repaired biliary atresia the value was increased near the normal range (mean 80.7%, SD 8.1). In neonatal hepatitis the value was variable in individual cases, but significantly lower than the normal (mean 47.6%, SD 19.9). TRCa was reduced in one third of the patients with unrepaired biliary atresia and in one fifth of the cases of neonatal hepatitis. The value was within the normal range in repaired biliary atresia. TRMg was decreased in both unrepaired and repaired biliary atresia and in neonatal hepatitis. The effect of intravenous calcium infusion on TRP, TRCa and TRMg was evaluated in 3 patients with unrepaired biliary atresia. TRP was conspicuously enhanced after infusion. TRCa was decreased in 3 to a variable extent. TRMg was moderately increased in 2 and greatly decreased in 1. These results indicate that infants with hepatobiliary disease are in a state of secondary hyperparathyroidism because of deficient or absent bile flow into the intestines.
