Changing trends in the prevalence of visual impairment, uncorrected refractive errors and use of spectacles in Mahbubnagar district in South India.
Article in Indian journal of ophthalmology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 3 of them syntheses that pooled 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.
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
BACKGROUND/
aimThe Andhra Pradesh Eye disease Study (APEDS) was a conventional cross-sectional study conducted in four locations during 1996-2000. Ten years later, a Rapid Assessment of Refractive Errors (RARE) survey was conducted in one of the geographical regions. The prevalence of visual impairment (VI), uncorrected refractive error (URE), spectacles use obtained from both the surveys was compared. SETTINGS AND
designRural settings; cross-sectional studies. MATERIALS AND
methodsIn both the surveys, distance visual acuity (VA) was assessed using a logMAR chart. Pinhole VA was assessed if presenting VA was <20/20 in APEDS and <20/40 in RARE. VI was defined as presenting VA <20/40 in the better eye. URE was defined as presenting VA <20/40 and improving to ≥20/40 with a pinhole. STATISTICAL ANALYSIS USED: Performed using Statistical Package for Social Sciences (SPSS). Chi square tests and t-test were used. RESULTS AND
conclusionsThe results from a RARE survey with 3,095 subjects were compared with an APEDS dataset that had 1,232 subjects in the same age group of 15-49 years. The prevalence of VI has decreased from 9.5% (95% CI, 7.7-11.1) in APEDS to 2.7% (95% CI, 2.1-3.3) in RARE. Similarly, the prevalence of URE in the better eye decreased from 5.8% (95% CI, 4.5-7.1) to 2.3% (95% CI, 1.8-2.8). The usage of spectacles increased from 6.6% (95% CI, 5.2-8.0) to 9.7% (95% CI, 8.7-10.7). There is a decreasing trend in the prevalence of VI and URE in Mahbubnagar district in Andhra Pradesh over a decade.
