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

purposeTo determine reference values for Japanese fetal penile length using ultrasonography at 18-21 + 6 as well as 28-31 + 5 weeks of gestation.

methodsThree hundred and five pregnant women were enrolled in the study, and fetal penile length was measured at both 18-21 + 6 and 28-31 + 5 weeks of gestation. All 305 fetuses were successfully measured. Outer penile length (OPL) of the male fetus was measured, and OPL reference values were determined. Intra- and inter-observer agreements regarding OPL were also assessed with Bland-Altman plots and intra- and inter-correlation coefficients.

resultsOPL showed an increasing trend with advancing gestation at 18-21 + 6 (r = 0.2757, p < 0.001) and 28-31 + 5 (r = 0.2306, p < 0.001) weeks. Intra- and inter-reproducibilities of OPL were excellent. Intra- and inter-correlation coefficients of OPL were 0.982287 and 0.885602, respectively, at 18-21 + 6 weeks, and 0.994104 and 0.97343, respectively, at 28-31 + 5 weeks.

conclusionOur results provide reference values for Japanese fetal penile length, which may promote accurate prenatal diagnoses of hypospadias, micropenis, and buried penis in Japan.
