The Newborn Infant Parasympathetic Evaluation Index for Assessment of Procedural Pain and Discomfort in Mechanically Ventilated Pediatric Intensive Care Patients: A Prospective, Exploratory, Observational 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
backgroundThe heart rate variability-based Newborn Infant Parasympathetic Evaluation (NIPE) Index is a continuous noninvasive tool for the assessment of pain and discomfort in infants. Little is known about its performance in the pediatric intensive care unit (PICU) setting, where assessment of pain/discomfort is usually based on discontinuous observational scoring systems or personal experience of medical staff.
aimEvaluation of the performance of NIPE as an indicator of procedural pain and/or discomfort in conscious mechanically ventilated PICU patients.
methodsProcedural pain/discomfort was simultaneously assessed during pain- or stressful procedures by two validated discontinuous clinical scoring systems (FLACC and COMFORT-B scale) and the NIPE.
resultsNIPE values, FLACC- and COMFORT-B scores were recorded in 17 infants with a mean age of 1.2 (range 0.8-5.9) months. NIPE values associated with positive FLACC- (≥ 4; indicative of pain) and/or COMFORT-B (≥ 17, indicative of discomfort) scores were lower (p < 0.001) than when associated with negative FLACC (< 4) and/or COMFORT-B (< 17) scores with 95% CI's of a difference of -14 to -11 (FLACC), -13 to -11 (COMFORT-B) and -14 to -11 (FLACC and COMFORT-B), with significant interindividual variability in NIPE values. Logistic regression analyses revealed odds ratios between 0.84 and 0.85; the adjacent receiver operating curve analyses showed areas under the curve between 0.83 and 0.88. NIPE data recording failure occurred during 49.3% of the periods with a FLACC ≥ 4% and 40.7% with a COMFORT-B ≥ 17.
conclusionsThe NIPE detects procedural pain and discomfort in conscious mechanically ventilated infants with an accuracy comparable to established clinical scoring systems. However, because of significant interindividual variability of NIPE values and frequent data recording failure associated with patient movement, we believe it is premature to recommend its use in conscious infants.
