The effects of bandpass filtering on the oscillatory potentials of the electroretinogram.
Article in Documenta ophthalmologica. Advances in ophthalmology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
purposeIn order to study the OPs, the ERG signal must be filtered to eliminate the low-frequency waves known as the a- and b-waves. Unfortunately, the ISCEV ERG standard does not give clear guidelines on how to proceed apart from indicating that frequencies below 75 Hz should be filtered out when recording scotopic OPs, while no suggestions are offered for the photopic OPs. The purpose of this study was thus to characterize more extensively the effects of various digital filters on the photopic OP waveforms in order to suggest the most appropriate filtering method to record them.
methodsFiltered OPs (N = 9600 tracings) were extracted from a photopic ERG databank of 40 normal subjects [intensity: 4.4 cd s m
resultsThe timing of the OPs was less affected than the amplitude by the different filters used. Depending on the filter used, the resulting OPs were either severely depressed (16.16% of broadband OP content) or slightly reduced (93.63%). The filters that most successfully eliminated the slow components of the ERG (i.e., < 12% of broadband value) were the Bessel, the Butterworth and the Chebyshev type 1 filters and out of the latter, the Butterworth filter was that which most faithfully reproduced the high-frequency OPs (i.e., > 96%).
conclusionOur results vividly demonstrate the need to better define the characteristics of the filter that is used to record the OPs as it does have a significant impact on the resulting waveform.
