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

Purpose: To study the intraoperative complications and postoperative clinical outcomes in different types of posterior polar cataract (PPC) following phacoemulsification, based on morphological classification. Methods: All consecutive patients with PPC who underwent phacoemulsification during the study period from 2016 to 2019 were included and sub-grouped based on the morphological characteristics according to Daljit Singh's classification. Intraoperative complications such as posterior capsular rupture (PCR), vitreous loss, nucleus drop, and Postoperative best-corrected visual acuity (BCVA) at day 1 and day 30 were documented. Results: A total of 388 eyes of 380 patients were included. Eighty nine (22.9%) eyes belonged to type 1, 135 (34.8%) belonged to type 2, 8 (2.1%) belonged to type 3, and 156 (40.2%) belonged to type 4. Thirty-five (9.3%) eyes had intraoperative PCR, with vitreous loss in 21 (60%) eyes, and nucleus/cortex drop in 5 (1.3%) eyes. Six (75%) eyes of type 3, 14 (10.04%) eyes of type 2, 12 (17.7%) eyes of type 4, and 3 (3.4%) eyes of type 1 PPC had PCR. PCR occurred more during the emulsification of the nucleus (18 cases, 51.4%). A significant correlation was seen between intraoperative PCR and type of PPC with a higher incidence in type 3 (P < 0.001). BCVA was found to be significantly worse on day 1 among patients with PCR compared to those who did not and improved well by day 30. Conclusion: PPC morphology is significantly co-related with the occurrence of PCR, emphasizing the need for careful grading of posterior polar cataracts in predicting the risk of intraoperative complications.
