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 compare the accuracy and precision of a conventional intraocular syringe to the Suh precision syringe (SPS), a new injection device designed to decrease operator error and to reduce adverse outcomes by providing a more ergonomic technique for periocular and intraocular injections.

methodsParticipants were instructed to inject a specified quantity of water into a 0.2 mL polymerase chain reaction (PCR) tube and a sheep eye, first with the conventional syringe, and then with the SPS. The degree of needle movement during injection was video recorded and analyzed for forward-retraction movement and variability in movement. The volume of water injected into the PCR tube was also documented. Data was analyzed using a Wilcoxon signed-rank test.

resultsAs compared to the conventional syringe, the SPS had significantly less forward-retraction movement when injecting into the sheep eye (

conclusionThe SPS demonstrates significant potential to decrease the overall risk involved with injections through reduction of forward-retraction movement during device operation. This new syringe design also provides better control with injection depth and drug injection volume. With its more ergonomic design, the SPS has the potential to decrease risks associated with intraocular injections by improving the accuracy and precision of the injection.
