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

backgroundPterygium is an ocular surface disorder with prevalence rates ranges from 0.3% to 29% in different parts of the world. Vascular endothelial growth factor (VEGF) has been detected in increased amounts in pterygium epithelium, compared with normal conjunctiva. Bevacizumab is a recombinant, humanized anti-VEGF antibody suggested as a possible adjunctive therapy for pterygium excision that appears to have a role in prevention of recurrence. We conducted this study to evaluate the role of subconjunctival bevacizumab in primary pterygium surgery in Indian patients.

methodsIn this randomized prospective clinical study, the patients were randomized into two groups of 30 patients each. Study group received 1.25 mg/0.05 ml subconjunctival bevacizumab 1 week before pterygium surgery with conjunctival autograft. Control group received 1.25 mg (0.05 ml) subconjunctival normal saline 1 week prior to pterygium surgery with conjunctival autograft. Patients were followed up at day 1, day 7, 1 month and 3 months. The main outcome measures were morphology of pterygium after injection, intra-operative ease, recurrence of pterygia, and any complications.

resultsAfter giving bevacizumab, there was statistically significant improvement in grade, color intensity, size of pterygium, and symptoms of patients. Intra-operatively, less bleeding was observed by the surgeon. No statistically significant difference regarding reduction in astigmatism, improvement of visual acuity, and complications were observed in two groups. Recurrence was noted in five patients (8.33%) in total study population at the end of 3 months. It was present in two patients (6.67%) in Group A and three patients (10%) in Group B.

conclusionSingle preoperative administration of subconjunctival injection bevacizumab given 1 week before the pterygium excision with conjunctival autograft decreases the vascularity of newly formed blood vessels, hence may decrease recurrence rate though not in our study.
