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 investigate the correlation between serum Rac1 enzyme (Rac1) level with asthma control, airway inflammatory response and lung function in asthmatic children.
methodsA retrospective analysis was performed on 79 children with asthma who were diagnosed and treated in our hospital from June 2020 to January 2023. According to the severity of the disease, the children were divided into mild group (25 cases), moderate group (30 cases) and severe group (24 cases). 36 healthy children who underwent physical examination at the same period in our hospital were selected as the control group. The state of an illness, control level, serum mRNA Rac1, inflammatory factors, and lung function of the children in two groups were compared between the control group and the observation group.
resultsThe Rac1 mRNA levels, forced vital capacity (FVC), forced expiratory volume in one second/FVC (FEV1/FVC), peak expiratory flow (PEF), and maximum mid-expiratory flow (MMEF) in the observation group were significantly lower than these in the control group (P < 0.05). The tumor necrosis factor-alpha (TNF-α), interleukin-5 (IL-5), IL-6, and IL-33 in the observation group were markedly higher than these in the control group (P < 0.05). As the state of an illness worsened, the Rac1 mRNA levels, FVC, FEV1/FVC, PEF, and MMEF gradually reduced (P < 0.05), while the levels of TNF-α, IL-5, IL-6, and IL-33 increased (P < 0.05). As the degree of disease control improved, the Rac1 mRNA levels, FVC, FEV1/FVC, PEF, and MMEF gradually elevated (P < 0.05), and the levels of TNF- α, IL-5, IL-6, and IL-33 showed the opposite trend (P < 0.05). Rac1 was negatively related to the levels of TNF-α, IL-5, IL-6 and IL-33 (P < 0.05), and positively to the levels of FVC, FEV1/FVC, PEF and MMEF (P < 0.001). Rac1 mRNA levels, FVC, FEV1/FVC, PEF and MMEF were protective factors, while TNF-α, IL-5, IL-6 and IL-33 were risk factors for the prognosis of children with asthma (P < 0.05).
conclusionChildren with asthma have obviously lower serum Rac1 mRNA levels, higher inflammatory factor levels and lower lung function. Serum Rac1 mRNA level may be associated with better asthma control, lower airway inflammatory response, better lung function and lower disease severity. It has important reference value for the evaluation of the state of an illness, efficacy and prognosis of children with bronchial asthma.
