Frequency and short-term persistence of haematuria and/or proteinuria in neonates: a cohort study.
Article in European journal of pediatrics, 2026. 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
purposeHaematuria and proteinuria may point to kidney diseases, but may also be found incidentally. Among schoolchildren, many studies suggest their prevalence to around 1%. In neonates, the frequency and persistence of haematuria and/or proteinuria in the general population have so far not been investigated systematically.
methodsIn the course of the prospective KUNO-Kids Health Study, urine samples were collected and analysed by dipstick in asymptomatic neonates on days three to five after birth. Those with positive findings underwent a maximum of two follow-ups until 16 weeks of age and factors associated with haematuria and/or proteinuria were explored.
resultsOf 509 participants with a urine sample available, 27% (n = 139) exhibited positive results. Of these, 58% (n = 81) had isolated haematuria, 21% (n = 29) had isolated proteinuria, and 21% (n = 29) had both. Of all children with positive urine tests, 76% (n = 105) underwent a first follow-up (mean 7 weeks later), and only in 1.9% (n = 2) was a positive result found. In the second follow-up (mean 2 weeks later), no positive results were detected anymore. Positive urine test results were more common in females and after vaginal delivery (p < 0.001 and p = 0.037, respectively).
conclusionThe present study identified haematuria and/or proteinuria in a significant proportion of healthy newborns shortly after birth, but results returned to normal within weeks in all participants available for follow- up. Thus, isolated findings of haematuria and/or proteinuria in newborns should be interpreted with caution. WHAT IS KNOWN: • Previous studies have reported the prevalence and persistence of haematuria and/or proteinuria in school- age children, but data on haematuria and/or proteinuria in neonates are scarce. WHAT IS NEW: • Positive urinary test results for haematuria and/or proteinuria are common after birth and were found in 27%. • Positive urinary test results returned to normal within 16 weeks in all children tested.
