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

backgroundTo determine the effectiveness of bone marrow-derived mesenchymal stem cell therapy on visual acuity and visual field in patients with retinitis pigmentosa.

objectiveStem cell treatment in retinitis pigmentosa provides improvement in visual acuity and visual field.

methodForty-seven eyes of 27 patients diagnosed with retinitis pigmentosa were included in our study. Allogeneic bone marrow-derived mesenchymal stem cells were administered by deep subtenon injection. Complete routine ophthalmological examinations, optical coherence tomography (Zeiss, Cirrus HD-OCT) measurements, and visual field (Humphrey perimetry, 30-2) tests were performed on all patients before the treatment and on the 1st, 3rd, and 6th month after treatment. The best corrected visual acuities of the patients were determined by the Snellen chart and converted to logMAR. Visual evoked potential (VEP) and electroretinogram (ERG) examinations of the patients before the treatment and on the 6th month after the treatment were performed (Metrovision) data were compared.

resultsVisual acuities were 0.74 ± 0.49 logMAR before treatment and 0.61 ± 0.46 logMAR after treatment. Visual acuity had a statistically significant increase (p < 0.001). The visual field deviation was found to be -27.16 ± 5.77 dB before treatment and -26.59 ± 5.96 dB after treatment (p = 0.005). The ganglion cell layer was 46.26 ± 12.87 μm before treatment and 52.47 ± 12.26 μm after treatment (p = 0.003). There was a significant improvement in Pattern VEP 120º P100 amplitude compared to that before the treatment (4.43 ± 2.42 μV) and that after the treatment (5.09 ± 2.86 μV) (p = 0.013). ERG latency measurements were 18.33 ± 15.39 μV before treatment and 20.87 ± 18.64 μV after treatment for scotopic 0.01 (p = 0.02). ERG latency measurements for scotopic 3.0 were 20.75 ± 26.31 μV before treatment and 23.10 ± 28.60 μV after treatment (p = 0.014).

conclusionRetinitis pigmentosa is a progressive, inherited disease that can result in severe vision loss. In retinitis pigmentosa, the application of bone marrow-derived mesenchymal stem cells by deep subtenon injection has positive effects on visual function. No systemic or ophthalmic side effects were detected in the patients during the 6-month follow-up period.
