Kidney dysfunction and beta S-haplotypes in patients with sickle cell disease.

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
objectiveTo investigate the association between kidney dysfunction and haplotypes in sickle cell disease.
methodsA cohort of 84 sickle cell disease patients, treated in a public health service in Fortaleza, Brazil, was studied. Hemoglobin S haplotypes were obtained from 57 patients as they had recently received blood transfusions with 18 of them agreeing to undertake urinary concentrating ability and acidification tests. The glomerular filtration rate was estimated using the Modification of Diet in Renal Disease Study equation. Urinary concentration was evaluated utilizing the urinary and serum osmolality ratio (U/Posm) after 12 hours of water deprivation. Urinary acidification was evaluated by measuring the urinary pH before and after the administration of oral CaCl2. The analysis of the haplotypes of the beta S gene cluster was carried out by polymerase chain reaction-restriction fragment length polymorphism. The analysis of variance (ANOVA) test was used for multiple comparisons of means and the Newman-Keuls test was used to identify which groups were significantly different.
resultsThe mean age of the patients was 33 ± 13 years with 64.2% being females. The glomerular filtration rate was normal in 25 cases (30%) and a rate > 120 mL/min was seen in 52 cases (62%). Urinary concentration deficit was found in all patients who underwent the test and urinary acidification in 22%. There was no significant difference when comparing patients with the Bantu/Bantu and Benin/Benin haplotypes. On comparing patients with the Central African Republic-haplotype however, a higher number had glomerular filtration rates between 60 and 120 mL/min.
conclusionThere was no significant difference among sickle cell disease patients regarding the haplotypes and kidney dysfunction.
