Comparative assessment of corneal biomechanical parameters in lactating versus non-lactating women: implications for refractive surgery candidates.
Article in International ophthalmology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTo assess and compare corneal biomechanical parameters between lactating and non-lactating women.
methodsThis analytical cross-sectional study included women aged 25-40 years with myopia or myopic astigmatism. The case group comprised women who had been lactating for more than six months. The control group comprised healthy, non-pregnant, non-lactating refractive-surgery candidates in the same age range. Corneal biomechanical properties were measured with the Corvis ST.
resultsFifty eyes from fifty lactating women (mean age: 31.28 ± 4.06 years) and a hundred eyes from one hundred non-lactating women (mean age: 30.68 ± 4.33 years) were included (P = 0.39). The median duration of breastfeeding was 12 months (range: 7-23 months). Initial analysis revealed significantly lower CCT, Radius, and stiffness parameter (SP-A1) in the lactating group compared to controls (P < 0.05). After adjusting for differences in CCT, no statistically significant differences were observed in any corneal biomechanical parameters (P > 0.05).
conclusionsCorneal biomechanical parameters in women who were lactating for over 6 months did not significantly differ from those of non-lactating women; these findings suggest that refractive correction surgery may be considered for such patients, pending further investigation.
