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

purposeEarly onset opacification of the lens (cataract) has been observed to be on the rise globally. This study was conducted to determine the various types of presenile cataract and to determine the probable risk factors associated with the occurrence of presenile cataract. MATERIALS AND

methodsPatients in the age group of 18-40 years attending the Out-Patient Clinic of the Ophthalmology Department who were found to have presenile cataract were recruited as cases. An equal number of consecutive patients of the same age group were included in the control group. Those who gave consent to participate in the study were interviewed through a preformed questionnaire and underwent a complete ocular examination and set of blood investigations. The type of cataract was noted, data obtained were compiled, and examination and investigations done were documented and analyzed using frequency distribution and Chi-squared test.

resultsIn total, 90 cases and 90 controls that fulfilled the inclusion criteria were recruited. Most common type of cataract was found to be posterior subcapsular cataract. Presenile cataract was observed to be significantly associated with tobacco intake (

conclusionsTobacco chewing, hypercholesterolemia, and excessive fuel exposure are risk factors for early development of cataract.
