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 investigate if preterm birth with very low birth weight (VLBW; birth weight < 1500 g) affects macular and visual pathway function in an adult population and explore if best corrected visual acuity (BCVA) was associated with any of the electrophysiologic responses.

methodsFifty participants born preterm with VLBW and 77 term-born controls years were recruited when aged 31-41 years from the Helsinki Study of Very Low Birth Weight Adults (Finland) and the NTNU Low Birth Weight Life study (Norway) studies. Pattern reversal electroretinogram (PR-ERG), visual evoked potential (PR-VEP) and BCVA were examined. PR-ERG components (P50, N95 peak time, amplitude and N95:P50 amplitude ratio) and PR-VEP components (N75, P100 and N145 peak time and amplitude) in the better-seeing eye were compared between the groups, and association with BCVA was examined.

resultsThe VLBW group showed longer N145 peak time compared to the control group (mean difference 6.8 ms, CI 2.0 to 11.5, p = 0.006) and lower N95:P50 amplitude ratio (CI - 0.3 to - 0.1, p = 0.003). Otherwise, both groups showed similar electrophysiological waveforms. No relationship was found between electrophysiologic responses and BCVA. BCVA was normal in birth groups and showed no group difference.

conclusionThe responses in the primary visual cortex (N75 and P100) to visual stimuli presented to the better-seeing eye were similar in adults born preterm with VLBW and term-born controls. However, in the VLBW group, there was an indication that subtle electrophysiological deviation may exist at a higher cortical level (N145) and in the ganglion cell response in the macula. These significant differences were not related to reduced visual acuity.
