Renal artery flow alterations in neonates with hypoxic ischemic encephalopathy.

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
backgroundTo compare kidney blood flow and kidney function tests in infants with hypoxic ischemic encephalopathy (HIE), and the effects of therapeutic hypothermia (TH) during the first 7 days of life.
methodsFifty-nine infants with HIE were prospectively evaluated. Infants with moderate-severe HIE who required TH were classified as group 1 (n = 36), infants with mild HIE were classified as group 2 (n = 23), and healthy infants were classified as group 3 (n = 60). Kidney function tests were evaluated on the sixth hour, third and seventh days of life in Group 1 and Group 2, and on the sixth hour and third day of life in group 3. Renal artery (RA) Doppler ultrasonography (dUS) was performed in all infants on the first, third, and seventh days of life.
resultsSystolic and end diastolic blood flow in RA tended to increase and RA resistive index (RI) tended to decrease with time in group 1 (p = 0.0001). While end diastolic blood flow rates in RA on the third day were similar in patients with severe HIE and mild HIE, it was lower in patients with mild-moderate-severe HIE than healthy newborns. On the seventh day, all three groups had similar values (p > 0.05). Serum blood urea nitrogen (BUN), creatinine, uric acid, and cystatin C levels gradually decreased and glomerular filtration rate (GFR) gradually increased during TH in group 1 (p = 0.0001). Serum creatinine levels gradually decreased while GFR gradually increased during the study period in group 2.
conclusionsTherapeutic hypothermia seems to help restore renal blood flow and kidney functions during the neonatal adaptive period with its neuroprotective properties.
