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

rationaleSurvivors of preterm birth (<37 weeks' gestation) have low peak oxygen uptake, a global measure of aerobic fitness and an established predictor of increased morbidity and mortality. However, little is known about other cardiopulmonary outcome measures in this population. We addressed the hypothesis that preterm birth is associated with abnormal respiratory, cardiovascular and metabolic responses to exercise, as assessed by cardiopulmonary exercise testing,

methodsSix databases were systematically searched up to 29 November 2024 (PROSPERO: CRD42022320775). Studies reporting cardiopulmonary outcome measures obtained during a standardised exercise test were included if they had preterm-born participants and matched term-born controls. The standardised mean difference (SMD) between pooled preterm-born and term-born cohorts was calculated using random-effects models for the meta-analysis.

resultsOf the 12 143 records identified, 47 cohorts were included in the final meta-analysis. At peak exercise, the preterm-born cohort (n=2149) demonstrated lower oxygen uptake (SMD -0.39, 95% CI -0.52 to -0.26), work rate (SMD -0.53, 95% CI -0.70 to -0.35), minute ventilation (SMD -0.43, 95% CI -0.60 to -0.26), tidal volume (SMD -0.38, 95% CI -0.62 to -0.15), oxygen pulse (SMD -0.47, 95% CI -0.75 to -0.19), heart rate (SMD -0.18, 95% CI -0.28 to -0.07), anaerobic threshold (SMD -0.29, 95% CI -0.49 to -0.08) and gas exchange efficiency (SMD 0.22, 95% CI 0.04 to 0.41), compared to the term-born cohort (n=1650).

conclusionsIn addition to a reduced peak oxygen uptake, survivors of preterm birth have impairments in the respiratory, cardiovascular and metabolic domains during cardiopulmonary exercise testing. Given that reduced aerobic capacity is associated with increased morbidity and mortality, exercise interventions that target cardiorespiratory fitness should be prioritised across the lifespan in those born preterm.
