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
backgroundTo clarify the correlation between the NF-κB1 gene initiation sequence -94ins/delATTG polymorphisms and the acute exacerbation of chronic obstructive pulmonary disease (AECOPD).
methodsBlood samples of 260 AECOPD patients were collected from September 2013 to September 2015 in the department of respiratory medicine, the Third Affiliated Hospital of Southern Medical University. Blood samples of 260 healthy subjects were collected as a control group. DNA was extracted using genomic DNA extraction kits and analyzed on a DNA quantitative analyzer. Data analysis was performed using Rotor-Gene (60001.7) to determine genotypes. SPSS20.0 was used to compare -94ins/delATTG polymorphisms between patients and healthy subjects. The relationship between the promoter sequence -94ins/delATTG of NF-κB1 genotypes and AECOPD were further analyzed.
resultsWe detected ins/ins, insertion or deletion (ins/del) and del/del genotypes from both the AECOPD and healthy control groups. The distribution of the three genotypes were consistent with the Hardy-Weinberg equilibrium law. The composition ratios of ins/ins, ins/del, del/del genotype distributions differed between AECOPD and control groups (P<0.05). The differences in ins/ins, ins/del and del/del genotype distributions between the two groups also significantly differed (P<0.05). The distribution of allele frequencies was comparable between the groups (P>0.05). The distribution ratio showed no relevance to the smoking index and clinical phenotypes of AECOPD patients, whether carrying ins/ins + ins/del genotypes or del/del genes (P>0.05). Compared to AECOPD patients with del/del genotypes, AECOPD patients with ins/ins + ins/del genotypes had a lower body mass index (BMI), a higher COPD assessment test (CAT) score, a larger number of acute episodes and longer hospital stays (P<0.05).
conclusionsThe detection of the -94ins/delATTG polymorphism in patients with AECOPD can predict disease prognosis. The BMI of patients with AECOPD was significantly lower in patients carrying the -94insATTG gene. Gene detection is therefore important in patients carrying ins/ins or ins/del genotypes following admission.
