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 evaluate whether oral beta-blockers (BBs) are associated with a decreased number of intravitreal injections in patients with incident neovascular age-related macular degeneration.

methodsA retrospective cohort study of subjects with a new diagnosis of neovascular age-related macular degeneration was conducted using a medical claims database from a large national US insurer. Two cohorts were created for comparison consisting of patients with regular use of BBs or calcium channel blockers. The main outcome measured was the difference in the mean number of intravitreal injections administered between the two cohorts.

resultsAfter inclusion and exclusion criteria, 239 BB and 155 calcium channel blocker subjects remained for analysis. Univariate analysis revealed that the mean number of injections in the BB cohort was 6.43 (95% confidence interval [CI] 5.90-6.95) versus 6.55 (95% CI 5.85-7.25) in the calcium channel blocker cohort (P = 0.78). After multivariate adjustment, the mean number of injections in the BB group was 6.32 (95% CI 5.77-6.87) versus 6.71 (95% CI 6.02-7.40) in the calcium channel blocker group. The overall difference between the 2 groups was -0.39 (95% CI difference -1.29 to 0.51; P = 0.40).

conclusionThe use of oral BBs is not associated with a decreased number of intravitreal injections in incident neovascular age-related macular degeneration patients.
