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 compare between the effect of early (3 months) and late (6 months) silicone removal on the electroretinogram records.

methodsThirty-four eyes with complex primary rhegmatogenous macula off retinal detachment undergone vitrectomy. Silicone oil was removed after 3 months in group I and after 6 months in group II. Scotopic and photopic ERGs, pattern electroretinogram (PERG) and multifocal ERG (mfERG) and best-corrected visual acuity (BCVA) were recorded for all eyes

resultsPreoperative mean best corrected visual acuity (BCVA) measured was 0.93 ± 0.05 in group I and 0.9 ± 0.08 in group II. One month after silicone removal, mean BCVA was 0.20 ± 0.04 and 0.18 ± 0.02 in groups I and II respectively. Before silicone oil removal the electroretinographic a- and b-waves were greatly reduced in both groups with no significant difference between them. One month after removal of silicone oil, the electroretinographic a- and b-waves increased in both groups with no significant difference between the two groups (p = 0.46 and 0.23 respectively).

conclusionThe amplitudes of the ERGs increase after removal of silicone oil tamponade with no difference between early (3 months) and late (6 months) removal.
