Assessing Diagnostic Accuracy of a Handheld Point-of-Care Device for Quantifying Neonatal Bilirubin Levels: The BEAT Jaundice @Home Study.

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
introductionThe Bilistick is a handheld point-of-care device for measuring total bilirubin levels in small blood volumes. We assessed its diagnostic accuracy and user convenience in near-term neonates cared for at home.
methodsA prospective cohort study was conducted in nine Dutch community midwifery practices. Neonates ≥35 weeks' gestation were eligible if they were at home between postnatal days 2-8 and had not received phototherapy. A Bilistick version 2.0 was used in parallel to laboratory-based bilirubin (LBB) quantification when significant visible jaundice was observed or the transcutaneous bilirubin reading was elevated.
resultsA total of 2,314 neonates were included in the study, with 423 blood samples analyzed across 13 laboratories. On 203 occasions, the Bilistick was not used. Among the remaining 220 Bilistick readings, 104 failed, and 2 lacked corresponding LBB results. A Bland-Altman plot of 114 paired measurements of Bilistick and LBB showed a mean difference of +9.7 µmol/L (0.57 mg/dL) with corresponding 95% limits of agreement of -179.7 to +199.2 µmol/L (-10.5 to 11.7 mg/dL). The positive predictive value of a Bilistick reading for having a total serum bilirubin level above the phototherapy threshold was 36.4%. The negative predictive value was 90.1%, sensitivity 60%, and specificity 77.6%. Hemolysis (24%) contributed to overestimations by the Bilistick. Community midwives expressed multiple barriers related to user convenience.
conclusionDiagnostic accuracy of the Bilistick when used in the home setting was limited. Its use was further hindered by a significant proportion of failed readings and low user convenience when operated by midwives.
