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
This study evaluated the effects of subclinical pregnancy toxaemia (SPT) on fetal skeletal muscle development and assessed the potential protective role of L-carnitine supplementation during gestation. A total of 18 crossbred Hamdani ewes underwent oestrous synchronisation, natural mating and pregnancy confirmation via ultrasonography on day 45 post-mating. The ewes were managed according to NRC (2007) dietary guidelines until day 100 of gestation, after which they were assigned to three experimental groups: subclinical PT group (group 1; G1, n = 6), treatment group (subclinical PT + L-carnitine, group 2; G2, n = 6) and control group (group 3; G3, n = 6). Blood β-hydroxybutyrate (βHBA) concentrations were measured on day 100 and 138 of the gestation. Then, all ewes were slaughtered for fetal muscle sampling from the Musculus Longissimus Dorsi (MLD) and Vastus Lateralis (VL). Results indicated a significant reduction in muscle fibre number and fibre diameter in both MLD and VL in the SPT group (G1) compared to the control (G3) (p < 0.05). No significant differences were observed between G1 and G2 or between G2 and G3 for these parameters (p > 0.05). On the other hand, large effect sizes for group and pairwise comparisons imply that SPT may negatively affect prenatal muscle development and L-carnitine supports muscle development during the prepartum period. These findings highlight the negative effects of SPT and protective effects of L-carnitine supplementation on fetal skeletal muscle development in ewes with SPT. The observed deficits may negatively impact postnatal growth, survival rates and meat quality. Further investigations are warranted to optimise maternal nutrition strategies and evaluate therapeutic interventions aimed at mitigating the adverse impacts of SPT on fetal muscle development in ruminants. Furthermore, L-carnitine supplementation may be a useful in compensating for the negative effects of SPT.
