Maternal seafood intake and the risk of small for gestational age newborns: a case-control study in Spanish women.
Article in BMJ open, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 papers.
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.
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 investigate the relationship between seafood consumption during pregnancy and the risk of delivering a small for gestational age (SGA) newborn.
designThis case-control study included women with SGA newborns and controls matched 1:1 for maternal age (±2 years) and hospital.
settingFive hospitals in Eastern Andalusia, Spain.
participants518 pairs of pregnant Spanish women. The SGA group included women who delivered SGA newborns: SGA was defined as a birth weight below the 10th percentile of infants at a given gestational age. Controls were women who delivered newborns with adequate birth weights.
interventionsWe collected data on demographic characteristics, socioeconomic status, toxic habits and diet. Midwives administered a 137-item Food Frequency Questionnaire. OUTCOME MEASURES: We calculated quintiles of seafood intake and applied conditional logistic regression to estimate ORs and 95% CIs.
resultsShellfish intake more than once/week yielded a significant protective effect against an SGA newborn (OR 0.25, 95% CI 0.08 to 0.76, after adjusting for energy, educational level, smoking, prepregnancy body mass index, weight and a history of preterm or low birthweight newborn). The risk of an SGA newborn was lower among women who consumed >121 g/day fish compared with women who consumed ≤56 g (adjusted OR 0.63, 95% CI 0.41 to 0.98; p=0.025 for a trend). Similarly, the risk of an SGA newborn was lower among women who consumed >1 g/day of marine n-3 polyunsaturated fatty acids compared with those who consumed ≤0.4 g/day (adjusted OR 0.58, 95% CI 0.38 to 0.90; p=0.025 for a trend).
conclusionAn average seafood intake of at least 121 g/day during pregnancy, equivalent to 3-4 servings/week, reduced the risk of an SGA newborn, compared with an average seafood intake of less than 56 g/day.
