1 · What the graph read from it

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.

2 · The registry

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

objectiveTo study the school performance of children with hypoxic ischaemic encephalopathy (HIE) relative to population controls from childhood to early adolescence.

designPopulation-based cohort study.

settingNew South Wales, Australia. PATIENTS: All 564 159 live-born infants ≥35 weeks' gestation born between 2008 and 2013 were eligible; 550 with HIE and 558 355 population controls. EXPOSURE: Mild, moderate-severe HIE.

main outcome measuresNational school assessment performance at 8-9, 10-11 and 12-13 years. SECONDARY OUTCOMES: reading, writing, spelling, grammar and numeracy scores at these ages. Linear regression models estimated the adjusted mean difference (aMD) at each timepoint. Hierarchical growth-curve modelling assessed academic trajectories (adjusted β).

resultsChildren with moderate-severe HIE had significantly lower total z-scores compared with controls at 8-9 years (aMD -0.70; 95% CI -0.84 to -0.52), 10-11 years (aMD -0.96; 95% CI -1.19 to -0.57) and 12-13 years (aMD -0.82; 95% CI -1.12 to -0.53), especially in reading and writing. The gap in overall mean scores remained fixed over time. Despite a lower likelihood of passing each year compared with controls, most infants with moderate-severe HIE passed each year (n=103, 62.4%). Children with mild HIE did not perform significantly differently from controls at 8-9 years (aMD -0.09; 95% CI -0.32 to 0.15), although there was a signal of worsening performance with age (β=13.54; 95% CI -21 to -6.07).

conclusionsChildren with moderate-severe HIE perform at a lower academic level than their peers, yet most meet national standards up to early adolescence. In contrast, children with mild HIE perform on par with their peers. This information is crucial for families: providing reassurance and a basis for needed support.
