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

purposeThe purpose of this study was to find the incidence of refractive surprise in patients of cataract with primary pterygium and compare it with patients of cataract without pterygium after phacoemulsification surgery.

methodsThe present observational study included 30 patients who had cataract with pterygium and 30 patients of cataract without pterygium. A detailed ophthalmic examination was done in all the cases. Horizontal corneal encroachment of pterygium from the limbus was measured. Keratometry and biometric measurements were performed preoperatively to determine the target refraction which was kept between - 0.50D and + 0.50D. The achieved spherical equivalent (SE) and prediction error were calculated postoperatively. A difference of >± 1.00D SE from the targeted postoperative refraction was considered a refractive surprise.

resultsThe mean age of patients was 61 ± 8.32 years. The mean extension of pterygium on the cornea was 2.3 ± 0.91 mm. Refractive surprise was seen in 16.7% of cases of cataract with pterygium and 10% of cases of cataract without pterygium.

conclusionOnly cataract surgery can be performed in patient having cataract with primary pterygium of up to 2.3 ± 0.91 mm horizontal corneal length, and the incidence of refractive surprise in these cases is comparable to that in patients of cataract without pterygium.
