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 study the change in P wave on electrocardiogram and its diagnostic value in children and adolescents with cardioinhibitory vasovagal syncope (VVS-CI).
methodsA total of 43 children and adolescents who were diagnosed with VVS-CI were enrolled as the VVS-CI group, and 43 healthy children and adolescents were enrolled as the control group. P wave duration and P wave voltage were measured by 12-lead electrocardiography in a basal state, and the changes were analyzed.
resultsCompared with the control group, the VVS-CI group had a significantly lower heart rate (P<0.05) and significantly longer P wave duration (Pwd), P wave maximum duration (Pmax), and corrected P wave maximum duration (Pcmax), as well as significantly higher P wave dispersion (Pd) and corrected P wave dispersion (Pcd) (P<0.05). Pwd, Pmax, Pd, Pcmax and Pcd had a certain diagnostic value in children and adolescents with VVS-CI (P<0.05): Pwd had a sensitivity of 69.77% and a specificity of 83.72% at the optimal cut-off value of 78.49 ms; Pmax had a sensitivity of 76.74% and a specificity of 90.70% at the optimal cut-off value of 93.39 ms; Pd had a sensitivity of 95.35% and a specificity of 69.77% at the optimal cut-off value of 27.42 ms; Pcmax had a sensitivity of 46.51% and a specificity of 88.37% at the optimal cut-off value of 120.90 ms; Pcd had a sensitivity of 83.72% and a specificity of 72.09% at the optimal cut-off value of 36.37 ms.
conclusionsChildren and adolescents with VVS-CI have significantly increased Pwd, Pmax, Pd, Pcmax, and Pcd, which may indicate abnormal atrial electrical activity. The cut-off value of P wave has a certain diagnostic value in VVS-CI.
