Are we ready for widespread implementation of lactate POCT in fetal blood sampling? An analytical and clinical verification of the novel statstrip POCT analyzer.

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
Objectives: Currently, pH values are used in fetal scalp blood sampling as a parameter to rule out fetal distress during the delivery. Due to a high number of pre-analytical errors in pH measurements, lactate measurement is already extensively examined as an alternative. Our objectives were to confirm the analytical performance of the StatStrip lactate POCT analyzer and to compare pH and lactate as a marker of fetal distress. Design: Results: The lactate concentration on the StatStrip analyzer correlated well with the iSTAT-1 (Pearson's r ≥ 0.95). 73 Fetal scalp blood tests showed 18% discrepant results when comparing pH and lactate with regard to fetal distress and consequent delivery intervention. Lactate showed more false positive results than pH (4 versus 1), but no false negatives as opposed to pH (0 versus 1). Conclusions: The lactate Statstrip and iSTAT-1 POCT analyzers were analytically equivalent. The clinical verification study showed that lactate is a good predictor of fetal distress, although more false positive results were found in our limited dataset. However, unnecessary interventions due to failed pH measurements might be prevented when a lactate measurement is introduced.
