1 · What the graph read from it

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.

2 · The registry

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

purposeTo evaluate reliability of steady-state pattern electroretinogram (ssPERG) phase variability in re-test (procedure called RE-PERG) in the presence of myopia, which is known to affect ssPERG amplitude, in glaucomatous patients (GP), normal controls (NC), and myopic patients (MY).

methodsThe procedure was performed on 50 GP, 35 NC, and 19 MY. All subjects were examined with RE-PERG, spectral-domain coherence tomography (SD-OCT), and standard automated perimetry (SAP). Standard deviation of phase (ssPERG SDph) and mean amplitude value (ssPERG Amp) of second harmonic (2ndH) were correlated, by means of one-way ANOVA and Pearson correlation, with mean deviation (MD) and pattern standard deviation (PSD) assessed by SAP and retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) thickness assessed by SD-OCT. Receiving operating characteristics were calculated in cohort populations with and without myopia.

resultsGP showed significant differences from the control group for MD, PSD, RNFL, GCC, ssPERG Amp, and ssPERG SDph; GP also showed significant differences from the MY group for all the parameters except for ssPERG Amp, which is reduced in both groups. In GP group, ssPERG Amp showed a specificity of 82.1% (95% confidence interval [CI]I: 66.5-92.5). In MY group, ssPERG Amp was reduced in 58% of the patients. As a consequence of this, in GP and MY groups, considered as a whole, total specificity dropped to 70.69% (95% CI: 57.3-81.9). In the GP group, ssPERG SDph showed a specificity of 84.6% (95% CI: 69.5-91.1). In both GP and MY groups, considered as a whole, ssPERG SDph total specificity increased from 84.6% to 93.1% (95% CI: 83.3-98.1).

conclusionIntrinsic phase variability of ssPERG is not influenced by myopia, even in the presence of fundus alterations.
