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
To investigate the value of very long chain acylcarnitine (VLCAC) and lysophosphatidylcholine (LPC) in screening of peroxisomal disease in children. Eighteen children with peroxisomal disease, including 14 cases of X-linked adrenoleukodystrophy (X-ALD group) and 4 cases of Zellweger syndrome (ZS group) diagnosed based on clinical symptoms, MRI and genetic tests were enrolled in the study; and 200 healthy children were selected as control group. Samples of dried blood spots were collected from all subjects, VLCAC and LPC in dried blood spots were extracted by solvent containing internal isotopic standards hexacosanoylcarnitine (H-C26) and C26:0 lysophosphatidylcholine (H-C26:0-LPC). The eicosanoylcarnitine (C20), docosanoylcarnitine (C22), tetracosanoylcarnitine (C24), hexacosanoylcarnitine (C26), C20:0 lysophosphatidylcholine (C20:0-LPC), C22:0 lysophosphatidylcholine (C22:0-LPC), C24:0 lysophosphatidylcholine (C24:0-LPC) and C26:0 lysophosphatidylcholine (C26:0-LPC) were detected by tandem mass spectrometry (MS/MS). The above 8 indicators and the ratios were compared among the groups using Kruskal-Wallis test and Mann-Whitney test; the contribution of each index to the disease were analyzed by partial least square method. Except C24:0-LPC/C20:0-LPC, there were significant differences in all indicators and ratios among all groups (<0.05 or <0.01). There were differences in most indicators and ratios between X-ALD group and the control group, as well as between ZS group and the control group, but there was no difference between the X-ALD group and the ZS group. PLS-DA analysis showed that the peroxisome disease group (including X-ALD group and ZS group) and the control group were able to be completely separated, and C26 had the highest variable importance for the projection (VIP) value. MS/MS detection of VLCAC and LPC can be used as a screening method for peroxisomal disease, and C26 may be a sensitive indicator for diagnosis.
