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 compare bone status of small-for-gestational age (SGA) versus appropriate-for-gestational age (AGA) newborn preterm infants. STUDY

designTibial speed of sound (SOS) was measured in 144 infants categorized as SGA or AGA using the reference tables of Lubchenco et al. and Alexander et al.

resultsBy the Lubchenco tables, 22% of infants were SGA and 75% were AGA. The mean gestational ages of SGA and AGA were similar (33.3+/-2.6 and 32.5+/-2.4 weeks, respectively, P = 0.09); however, SGA infant birth weights were lower (1329+/-392 and 1829+/-481 g, respectively, P<0.001). SOS values were higher for SGA versus AGA infants (3098+/-135 and 3003+/-122 m/s, respectively. P<0.001). Use of the Alexander tables yielded a twofold increase in the percent of infants categorized as SGA; SOS values remained significantly greater for SGA infants (P<0.001).

conclusionHigher tibial SOS values in SGA versus AGA infants indicate greater bone strength.
