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

The nexus between early-life residential greenness and sleep health in children remains underexplored. This research investigated associations of early-life greenness exposure with sleep outcomes among 101,879 preschoolers from 551 Chinese cities. Sleep status was evaluated using the Children's Sleep Habits Questionnaire (CSHQ). Greenness was estimated using satellite-derived Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI) surrounding participants' home during pregnancy and post-birth period. Linear mixed-effect and random-effects logistic regression models were used to assess associations of greenness with CSHQ scores and sleep disturbance, respectively. Mediation effects of air pollution and residential distance to major roads were examined. Both prenatal and postnatal greenness exposures were significantly associated with better sleep outcomes. Specifically, an interquartile range increment in NDVI within the 250-m buffer during the entire pregnancy and from birth to investigation was associated with reductions in the total CSHQ score by 0.21 (95% confidence interval [CI]: 0.14, 0.28) and 0.22 (95% CI: 0.15, 0.29), respectively. Corresponding odds ratios for sleep disturbance were 0.96 (95% CI: 0.94, 0.98) for both periods. These associations remained consistent when considering larger buffers (500-m and 1000-m), and employing other greenness metrics like EVI and growing-season NDVI. The association between postnatal greenness exposure and sleep disturbance was partially mediated by PM
