Evaluating the Diagnostic Utility of Spinal Ultrasound in Neonates With a Simple Sacral Dimple: An Eight-Year Retrospective 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
introductionSpinal dysraphism describes a spectrum of congenital anomalies pertaining to the spine and spinal cord. Ultrasound is the preferred imaging modality for diagnosing dysraphism in low-risk neonates due to its cost-effectiveness and availability. Recent research demonstrates a low incidence of dysraphism in infants with an isolated sacral dimple and associated cutaneous stigmata (e.g., hairy tuft, haemangioma). We sought to determine the number of neonates referred for investigation of a simple sacral dimple, and the proportion found to have dysraphism.
methodsA retrospective analysis of the radiology information system was performed in a quaternary Australian children's hospital. Children undergoing spinal ultrasound from January 2016 to November 2024 were included. Patients over 90 days of age, and with indications other than simple sacral dimple were excluded.
resultsThere were 448 spinal ultrasound examinations reviewed; of these, 195 (43.5%) were for a simple sacral dimple. Mean age at scan was 33 days (range 2-90 days, sd = 24 days), 88 (45.1%) were female. Only two (1.0%) were diagnosed with dysraphism; both were found to have tethered cords. Both patients were subsequently diagnosed with concomitant anomalies (cardiac, and a Dandy Walker Malformation).
conclusionOur findings support literature suggesting ultrasound screening for neonates with a simple sacral dimple has a very low diagnostic yield.
