Management of asymptomatic cardiac murmurs in term neonates.

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
Approximately 2 % of newborn infants are noted to have cardiac murmur on routine postnatal examination. Our aim was to look at current evidence and practice in the management of asymptomatic cardiac murmur in term neonates. We performed a systematic literature review and a telephone survey of all neonatal units in the United Kingdom (UK). The systematic review of the literature did not support the routine practice of four-limb blood pressure (BP), chest X-ray (CXR), and electrocardiogram (ECG) in the assessment of asymptomatic cardiac murmur in term neonates. The survey had participation from 132 (68 %) of 193 neonatal units in the UK. In an asymptomatic term neonate with cardiac murmur, 124 (94 %) units perform pulse oximetry, 100 units (76 %) measure four-limb BP, 36 units (27 %) perform a CXR, and 52 units (39 %) perform an ECG. Eight-six units (65 %) have availability of in-house echocardiography services provided mainly by paediatricians with cardiology interest in special care units and neonatologists in neonatal intensive care units. Currently there is wide variation in practice in the management of asymptomatic cardiac murmur in term neonates. There is no evidence to support the routine use of four-limb BP, CXR, and ECG in the assessment of asymptomatic cardiac murmur in term neonates. Based on the evidence available, both structured clinical examination (including determining presence and quality of bilateral femoral pulses) and universal use of pulse oximetry are most important in identifying CHD in asymptomatic term neonates with cardiac murmur before discharge home.
