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
Background: Type 1 diabetes mellitus (T1DM) is a chronic autoimmune condition that can lead to long-term complications due to oxidative stress and metabolic dysregulation. Paraoxonase-1 (PON-1), an enzyme associated with high-density lipoprotein (HDL), has dual activities: arylesterase and lactonase. These activities protect lipids from oxidative damage. The functional status of PON-1 in children with T1DM may provide insights into the relationship between oxidative stress and the enzyme's protective role. This study aims to assess the arylesterase and lactonase activities of PON-1 in Iraqi children with T1DM. Methods: Sixty-seven children with T1DM were enrolled and compared with 57 age-matched healthy controls. The enzymatic activities of arylesterase and lactonase were measured to evaluate PON-1's functional status. The Paraoxonase-1/HDL (PON/HDL) ratio was calculated to assess lipid protection and antioxidant capacity. Oxidative status was assessed by measuring total oxidative status (TOS), total antioxidant status (TAS), and oxidative stress index (OSI). Results: PON-1 activity analysis showed a significant reduction in arylesterase (2.36 ± 1.17) and lactonase (21.9 ± 7.31) in the patients group compared to controls (arylesterase=4.54 ± 1.84, lactonase =29.51 ± 9.92). TOS and OSI were significantly higher, while TAS was significantly lower in the patients group. Pearson correlation revealed a positive correlation between HDL-C and arylesterase (P = 0.002, r = 0.379), and HDL-C and lactonase (P = 0.040, r = 0.366). Conclusions: Reduced PON-1 activity is associated with T1DM, suggesting that enhancing PON-1 or reducing oxidative stress may help prevent diabetic complications and improve cardiovascular health.
