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

objectiveUsing 2 nationwide population-based datasets, this study aimed to assess the risk of adverse pregnancy outcomes, including low birthweight (LBW), preterm birth, small for gestational age (SGA), cesarean section (CS), lower Apgar score, and preeclampsia/eclampsia, between women with and without pneumonia. STUDY

designThis study included 1462 women who had been hospitalized with pneumonia during pregnancy and used 7310 matched women without pneumonia as a comparison group.

resultsCompared to women without pneumonia, conditional logistic regression analyses showed that the adjusted odds ratios for LBW, preterm birth, SGA, CS, Apgar scores <7 at 5 minutes, and preeclampsia/eclampsia in women with pneumonia were 1.73 (95% confidence interval [CI], 1.41-2.12), 1.71 (95% CI, 1.42-2.05), 1.35 (95% CI, 1.17-1.56), 1.77 (95% CI, 1.58-1.98), 3.86 (95% CI, 1.64-9.06), and 3.05 (95% CI, 2.01-4.63), respectively.

conclusionWomen with pneumonia during pregnancy had significantly higher risk of LBW, preterm birth, SGA, low Apgar scores infants, CS, and preeclampsia/eclampsia, compared to unaffected women.
