Intervention at an early threshold for post-hemorrhagic ventricular dilatation in preterm infants: a systematic review and meta-analysis.

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
backgroundVery few adequately powered studies exploring early thresholds for intervention in the management of post-hemorrhagic ventricular dilatation (PHVD) in preterm infants have identified consistent neurodevelopmental advantages at 12-30 months. We aimed to conduct a meta-analysis on the efficacy and safety of early versus conservative thresholds for intervention, primarily aimed at normalizing cerebrospinal fluid (CSF) pressure, in the management of PHVD in preterm infants.
methodsMultiple databases were searched for eligible papers, and prospective randomized trials involving preterm infants were selected. The results are expressed as relative risks (RRs) with 95% confidence intervals (CIs). The main outcome was survival without moderate-to-severe neurodevelopmental impairment at 12-30 months.
resultsTen articles representing seven randomized trials comparing early versus conservative thresholds for interventions were included. Five trials (n = 545 infants) reported no difference in the main outcome between early and conservative groups [RR 0.99 (0.71, 1.37)]. Sensitivity analysis excluding data from a medication trial did not alter the main outcome [RR 1.15 (0.95, 1.39)]. Infants in the early threshold group received significantly more interventions [RR 1.48 (1.05, 2.09)]. Deaths before discharge/during the initial study period [RR 1.04 (0.70, 1.54)] or a composite of death or shunt insertion [RR 1.04 (0.86, 1.27)] were comparable between the two groups.
conclusionsEarly intervention for PHVD, before a clinical or ultrasound threshold is met, leads to additional clinical procedures but does not improve survival without moderate-severe neurodevelopmental impairment at 12-30 months. Caution should be exercised in interpreting these results due to significant variation between the studies. Supplementary file 3 (MP4 131172 kb).
