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
backgroundPrenatal alcohol exposure (PAE) is a major public health concern, yet no reliable clinical tools are available for assessing levels of drinking during pregnancy. Fatty acid ethyl esters (FAEEs), the non-oxidative metabolites of ethanol in meconium, are potential biomarkers for quantifying PAE.
methodsIn a prospective birth cohort of children exposed to alcohol and drugs in utero, meconium from 216 newborns was analyzed. FAEE concentrations were quantified with gas chromatography via a flame ionization detector. A factor score was derived via a principal component analysis of six FAEE analytes. Expressive and receptive language were assessed in 189 children (56% girls) at ages 10 and/or 12.
resultsHigher FAEE factor scores were related to lower receptive language, with its harmful effect mitigated by non-kinship care at lower levels of FAEEs (p = 0.03). This relationship remained significant after adjusting for child IQ (p = 0.008). Expressive language showed a non-significant trend (p = 0.09), which disappeared after IQ adjustment (p > 0.30). Other prenatal drug exposures were unrelated to the effects of FAEEs on language skills.
conclusionsElevated levels of FAEEs in meconium can be potential biomarkers for identifying newborns at risk for poor language development related to PAE. IMPACT: Higher concentrations of Fatty acid ethyl esters (FAEEs), the non-oxidative metabolites of ethanol, analyzed in meconium, are associated with lower receptive language at 10 and 12 years of age, but their harmful effect was mitigated at lower levels of FAEEs by the more enriched caregiving environment of non-kinship care. Elevated levels of FAEEs in meconium can be potential biomarkers for identifying newborns at risk for poor language development related to prenatal alcohol exposure (PAE). FAEEs may provide diagnostic clarity for PAE, allowing the identification of moderate and episodic PAE, which is unlikely to be detected at birth.
