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

purposeContradictory evidence exists over the best approach for the management of submacular hemorrhage (SMH). In this study, we compared the outcomes of subretinal versus intravitreal injection of recombinant tissue plasminogen activator (r-tPA) and gas in cases of SMH secondary to age-related macular degeneration (AMD).

methodsTwenty five eyes with SMH were retrospectively divided in 2 groups. Group A underwent vitrectomy, subretinal r-tPA and gas (Vitrectomy group, n = 14), and group B received intravitreal r-tPA and gas (Pneumatic group, n = 11). SMH displacement and change in subfoveal hemorrhage thickness (SFHT) at 1 month post-op were assessed. Additionally, best corrected visual acuity (BCVA) and central retinal thickness (CRT) at the end of the 12 month follow-up (FU) were analyzed. Clinical and epidemiological prognostic factors were tested.

resultsMean duration of SMH prior intervention was 8.2(± 7.3) days. Baseline BCVA was 1.53 ± 0.73 LogMAR, mean extension of SMH was 4.604 ± 2079 μm and mean CRT pre-treatment was 795 ± 365 μm. SMH displacement at 1 month post-treatment was total in 9/14 versus 6/11 and partial in 4/14 versus 2/11 in Group A and Group B, respectively (Fisher's exact test p = 0.38). SFHT reduced by 404 ± 312 μm in Group A versus 376 ± 405 μm in group B (p = 0.86). BCVA improvement and reduction of CRT were highly significant at the end of FU (p = 0.002 and p < 0.001 respectively) but did not differ between the 2 groups. Only baseline BCVA and preoperative CRT proved to be significant prognostic factors for the final functional outcome (p = 0.013 and p = 0.047 respectively).

conclusionBoth treatment options proved equal efficacy in displacing SMH in AMD. A multicenter trial may delineate a desirable algorithm of treatment.
