Article in BMJ (Clinical research ed.), 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 1 of them a synthesis that pooled it.

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 examine the diagnostic accuracy of clinical examination to determine fetal presentation in late pregnancy.

designCross sectional analytic study with index test of clinical examination and reference standard of ultrasonography.

settingAntenatal clinic in tertiary obstetric hospital in Sydney, Australia.

participants1633 women with a singleton pregnancy between 35 and 37 weeks' gestation attending antenatal clinics.

interventionFetal presentation assessed by clinical examination during routine antenatal care, followed by ultrasonography to confirm the diagnosis.

main outcome measuresSensitivity, specificity, and positive and negative predictive values of clinical examination compared with ultrasonography. Diagnostic rates by maternal characteristics.

resultsUltrasonography identified non-cephalic presentation in 130 (8%) women, comprising 103 (6.3%) with breech and 27 (1.7%) with transverse or oblique lie. Sensitivity of clinical examination for detecting non-cephalic presentation was 70% (95% confidence interval 62% to 78%) and specificity was 95% (94% to 96%). The positive predictive value and negative predictive value were 55% and 97%, respectively.

conclusionsClinical examination is not sensitive enough for detection and timely management of non-cephalic presentation.
