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

To determine the efficacy of the treat and extend (TAE) protocol with intravitreal bevacizumab (IVB) for managing diabetic macular edema (DME).Retrospective, single-center study.For this retrospective study, 42 eyes of 42 patients were initially treated with 3 consecutive monthly IVB injections (loading phase), after which they were selected for different additional therapies. For the TAE protocol, the baseline treatment interval was selected to be 8 weeks and was sequentially lengthened by 2 weeks if the central macular thickness (CMT) was <300 μm at 2 consecutive examinations.Among the 42 eyes, 8 eyes (19.0%) received the TAE treatment for 2 years. The BCVA was improved significantly from 0.37 ± 0.04 before treatment to 0.19 ± 0.04 logMAR units at 2 years after the TAE determined IVB injections (P < .05). The ratio of eyes with a gain of the BCVA by more than 2 lines was 37.5%. The CMT was significantly reduced from 515.4 ± 75.5 to 303.6 ± 45.0 μm after 2 years (P < .01). The mean number of TAE injection was 8.8 and the mean injection interval was 11.0 weeks.After the loading phase, 19.0% of patients can be treated with the TAE protocol. Although significant visual improvements were obtained after the TAE protocol, it does not apply to every DME case.
