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 analyze the association between low birth weight (LBW) and intrauterine growth restriction (IUGR) with handgrip strength (HGS) in adolescents.
methodsBirth cohort study from São Luís, Maranhão, Brazil, conducted between 1997 and 1998. The Jamar Plus+ dynamometer was used to measure HGS during the second follow-up. Birth weight was assessed from information from the participants' hospital records. LBW was defined as a birth weight <2500 g, while IUGR was defined as a Kramer's index <0.85. The associations of LBW and IUGR with HGS were estimated using linear regression models. The directed acyclic graph (DAG) was used to identify the variables for adjustment.
resultsWe evaluated 544 individuals who participated in the baseline and second follow-up, and 279 who participated in the first and second follow-ups. In crude and adjusted analyses, LBW was not associated with HGS. However, in the crude analysis, male adolescents with IUGR had lower HGS (β: -4.17; 95%CI -7.67; -0.66) compared with those without IUGR. In the adjusted analysis, the association was maintained, with male adolescents with IUGR showing a reduction of 4.36 kgf (β -4.36; 95%CI -7.88; -0.85) in HGS compared with those without IUGR. There was no association between IUGR and HGS in females.
conclusionsLBW was not associated with HGS. However, male adolescents with IUGR had lower HGS.
