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
A part of aneurysmal subarachnoid hemorrhage (aSAH) patients with the hydrocephalus require permanent cerebral spinal fluid diversion and have poor prognosis. Evaluating the risk of shunt dependent hydrocephalus is important for clinicains to make personalized treatments strategies. This study was performed to explore the relationship between initial serum uric acid (SUA) level and the shunt dependent hydrocephalus of aSAH patients. The primary outcome of the study was the shunt dependent hydrocephalus. Laboratory examinations including SUA were extracted by analyzing the first blood sample after admission. Risk factors for shunt dependent hydrocephalus of aSAH was explored by univariate and multivariate logistic regression. The relationship between SUA and risk of shunt dependent hydrocephalus was shown using the restricted cubic spline (RCS) method. The logistic regression based predictive model for shunt dependent hydrocephalus of aSAH was developed by incorporating independent risk factors discovered in the multivariate logistic regression. The receiver operating characteristic curve (ROC) was drawn to evaluate the predictive accuracy of SUA and the developed model for shunt dependent hydrocephalus of aSAH. 715 aSAH patients were enrolled with the hydrocephalus incidence of 7.7%. Compared with non-hydrocephalus group, hydrocephalus group had older age (p = 0.006), higher rate of alcoholism (p = 0.017), higher WFNS (p < 0.001) and Hunt Hess (p < 0.001), higher level of SUA (p < 0.001). Moreover, aSAH patients with the hydrocephalus had higher incidence of delayed cerebral ischemia (p = 0.001), higher mortality (p = 0.004), longer length of ICU stay (p < 0.001) and length of hospital stay (p < 0.001). Five independent risk factors for the shunt dependent hydrocephalus of aSAH patients were confirmed by the multivariate logistic regression including age (p = 0.011), alcoholism (p = 0.014), WFNS (p = 0.025), white blood cell (p = 0.003), SUA (p = 0.020). The AUC of SUA for predicting the hydrocephalus was 0.643. Incorporating five factors discovered in the multivariate logistic regression, the predictive model for shunt dependent hydrocephalus had an AUC of 0.780. Increased SUA level is independently associated with the shunt dependent hydrocephalus after aSAH. The predictive model incorporating serum uric acid is useful for clinicians to evaluate the risk of shunt dependent hydrocephalus after aSAH and make suitable therapeutic schedule.
