Prevalence of Astigmatism in Patients Undergoing Cataract Surgery at a Tertiary Care Center in North India.
Article in Clinical ophthalmology (Auckland, N.Z.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
aimTo assess the demography, magnitude, and type of corneal astigmatism in patients undergoing cataract surgery in North India.
methodsIt is a clinic-based, cross-sectional, observational study. Keratometric values and demographic data were collected for eligible patients who had undergone phacoemulsification at a tertiary eye care center between January 2010 and December 2017, using a non contact, optical low coherence reflectometry (OLCR).
resultsA total of 3597 eyes were recruited for the study. There were 1810 (50.3%) females and 1787 (49.7%) males. The mean age was 59.121±15.19 (range 5-100 years). A total of 3559 eyes were qualified for astigmatism analysis. The mean corneal astigmatism among all patients was 1.17±1.15 D (range 0-12.5 D). There was no astigmatism in 99 eyes (2.78%), with-the-rule (WTR) in 1062 eyes (29.83%), against-the-rule (ATR) in 1843 eyes (51.72%) and oblique astigmatism (OA) in 555 eyes (15.59%). The tendency of a gradual change from with the rule (WTR) to against the rule (ATR) astigmatism was noted as the age advanced.
conclusionIn the present study around 56.69% of eyes had corneal astigmatism of <1.0 D that can be managed by simple cost-effective keratorefractive procedures especially in developing countries. However, our 40.49% patients had >1.0 D of corneal astigmatism, which may benefit by toric intraocular lenses.
