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

backgroundInfants with low birth weight are at increased risk of developing insulin resistance later in life.

objectivesTo evaluate differences in adipocyte size during early childhood between infants with low birth weight and infants born appropriate for gestational age at full-term.

methodsThis cross-sectional study included 92 children (77 infants born appropriate for gestational age at full-term and 15 with low birth weight), aged 0.8-5.2 years, scheduled for surgery. Adipose tissue samples were obtained intraoperatively, fixed in osmic acid, and assessed for mean adipocyte diameter after adipocyte separation.

resultsDespite a similar body mass index, the low-birth-weight group had larger mean adipocyte diameters during early childhood than the term appropriate-for-gestational-age group (87.0 μm vs. 74.7 μm). Multiple regression analysis revealed that low birth weight and higher body mass index at surgery were significant determinants of larger mean adipocyte diameter (p < 0.001). Mean adipocyte diameter was not associated with haematological parameters, including insulin, adiponectin, and leptin levels.

conclusionDuring early childhood, infants with low birth weight had larger adipocytes than infants born appropriate for gestational age at term. Further studies are required to determine whether this observation is associated with insulin resistance development later in life.
