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 determine the significance of the correlation between optical coherence tomographic (OCT) findings and focal macular electroretinograms (fmERG) at 12 months after beginning intravitreal injections of ranibizumab (IVR) in eyes with age-related macular degeneration (AMD). STUDY

designProspective, clinical study.

methodWe studied 28 eyes of 28 patients with AMD treated with IVR at monthly intervals for the initial three months. Additional IVR was given according to a pro re nata (PRN) regimen. OCT and fmERGs were performed preoperatively and at 3 and 12 months postoperatively. The fmERGs were elicited by a 15° white stimulus spot centered on the fovea. The thickness of the inner, middle, and outer layers of the retina and also of the serous retinal detachment (SRD) and pigment epithelial detachment (PED) in the horizontal and vertical meridians at 1.2 mm from the fovea (parafoveal) were measured in the OCT images.

resultsThe b-wave amplitude at 12 months was significantly correlated with the thicknesses of the outer retinal layer, SRD, and PED (P=0.001-0.02). Multiple regression analyses showed that the outer retinal layer thickness was an independent determinant (P= 0.0001). The changes in the b-wave amplitude between the baseline and 12 months were significantly correlated with the changes in the SRD thickness (P=0.006). The changes in the b-wave amplitude during the PRN period were significantly correlated with the changes in the PED thickness (P=0.02).

conclusionsAt 12 months after beginning treatment, the reduction in the SRD thickness affects macular function recovery. As recurrences of the PED can occur during the PRN period, control of the PED is necessary to obtain good macular function for the long term.
