Variations in the central corneal thickness during the menstrual cycle in Indian women.
Observational study in Indian journal of ophthalmology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
purposeTo determine the changes in central corneal thickness (CCT) during the menstrual cycle in Indian women.
methodsA prospective observational clinical study at a tertiary care center between December 2015 and December 2018. One hundred and twenty sixty women between 18 and 45 years were included. The CCT was measured using an ultrasound pachymeter at three specific timelines of the menstrual cycle: at the beginning (1
resultsThe mean CCT of both eyes was 541.76 ± 4.21 μm, 559.21 ± 4.50 μm, and 544.52 ± 8.06 μm at the beginning, mid, and end of cycle, respectively. The mean CCT of the right eye was 541.68 ± 4.15 μm, 559.08 ± 4.50 μm, and 544.44 ± 8.06 μm and of the left eye was 541.84 ± 4.27 μm, 559.35 ± 4.50 μm, and 544.61 ± 8.06 μm at the beginning, mid, and end of cycle, respectively.
conclusionThe CCT value was significantly (P < 0.001) higher during ovulation compared to the beginning and end of the menstrual cycle. Our study recommends adding menstrual history in the workup of women undergoing refractive surgery as physiological variations in the CCT may result in unexpected surgical outcomes.
