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

purposesTo compare surgeons' opinions regarding idiopathic full-thickness macular hole (MH) surgery by using traditional microscopy and three-dimensional (3-D) visualization system. To analyze the required time for pars plana vitrectomy (PPV) and for internal limiting membrane (ILM) rhexis by using both visualization methods. To evaluate anatomical surgical results.

methodsFour surgeons (surgeon 1, fellows 1, 2, 3) performed the total of 40 surgeries for treating MHs. Each one performed 10 surgeries (5 with traditional microscopy and 5 with 3-D visualization). The completion time for PPV and ILM rhexis was determined by using both methods. Ergonomics, educational value, image sharpness, depth perception, field of view and technical skills were analyzed through answering a questionnaire.

resultsForty patients were included in the study. The MH size for surgeon 1, fellows 1, 2 and 3 groups, individually, ranged from 237 to 602 μm; 228 to 590 μm, 271 to 611 μm and 289 to 600 μm, respectively. In the 3-D and in the traditional microscopy subgroups (which includes all 4 physicians on the use of one or the other method), the MH size ranged from 228 to 602 μm and 237 to 611 μm, respectively. Comparisons between the average time for full PPV and ILM rhexis by using the two methods were non-significant, neither in each individual case of 3-D surgery for each surgeon. Surgeon 1 had always been faster than his fellows. Depth perception was rated as similar for both methods. Field of view and educational values were rated as superior when using the 3-D system. Image resolution and ergonomics were rated as superior when using traditional microscopy. Technical skills strongly tended toward 'superiority' when using traditional microscopy. Thirty-six (90%) full-thickness MHs were successfully closed with one surgery.

conclusionThe 3-D system for MH surgery had a short learning curve and was a refined educational tool, when used with reduced illumination and precise focus. Concerning MH surgery, heads-up method was similar to traditional microscopy regarding length of time and anatomical surgical results. Heads-up surgery may become a new pattern for ophthalmic surgery as ongoing improvements are applied.
