Control of precision grip in children with heavy prenatal alcohol exposure.
Article in Alcohol, clinical & experimental research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundFine motor skill deficits have been reported for children with histories of prenatal alcohol exposure, but little is known whether impaired motor skill extends to the regulation of precision grip control.
methodsChildren with (n = 15) and without (n = 17) histories of heavy prenatal alcohol exposure used their dominant hand to grasp, lift, and hold in space a small-instrumented object with a mass of 19 g. Object mass was also experimentally increased by separately adding two aluminum cubes with mass of 200 and 400 g. Participants completed a block of eight trials for each object mass with the last six trials in each trial block being statistically analyzed. Selected temporal and kinetic parameters of grip force (GF) and load force (LF) were examined to quantitatively index precision grip performance of the two groups.
resultsCompared to typically developing peers, children with prenatal alcohol exposure used excessive and more variable LF and greater GF to lift each object mass, with more finger GF than thumb GF being applied to the apparatus. The GF/LF ratio for the clinical group was greater when lifting the smallest mass load. When holding the object in space, children with prenatal alcohol exposure produced greater GF for the smallest mass load, again with more GF being applied via the finger compared to the thumb.
conclusionsChildren with heavy prenatal alcohol exposure demonstrate force deficits when using precision grip to manipulate an object with three different masses. Chronic irregular precision grip could manifest as a fine motor skill developmental delay that may negatively impact completion of functional activities of daily living requiring grasping an object with the index finger and thumb.
