1 · What the graph read from 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.

Abstract

backgroundPulmonary hypertension (PH) is a common chronic complication of sickle cell disease (SCD), and patients at risk for PH can be identified by measuring tricuspid regurgitant jet velocity (TRJV). We looked for the possible efficacy of L-arginine for children with SCD who have elevated TRJV.

methodsIn total, 50 children with SCD who had TRJV higher than 2.5 m/s were randomly divided into two groups, each with 25 patients: group 1 (control group) and group 2 (treatment group). Group 2 received L-arginine at a dose of 0.1-0.2 g/kg/day for 3 months. Transthoracic echocardiography was conducted to measure TRJV at baseline and after 3 months, and blood samples were collected at baseline and after 3 months to assess serum levels of N-terminal pro-brain natriuretic peptide (NT-proBNP), lactate dehydrogenase (LDH), nitric oxide (NO), L-arginine (LA), asymmetric dimethylarginine (ADMA), and LA/ADMA ratio.

resultsAfter 3 months of treatment, the L-arginine-treated group had significantly lower TRJV levels than the control group, and compared with baseline. They also had significantly lower NT-proBNP and significantly higher NO, LA and LA/ADMA ratios than the control group and compared with baseline. No significant differences in side effects were observed between the two groups, indicating that L-arginine is safe for these patients.

conclusionsL-arginine is associated with a reduction in TRJV, NT-proBNP, and improvements in NO biomarkers, suggesting it may be beneficial for reducing the risk of pulmonary hypertension in children with sickle cell disease. CLINICAL
