Lens densitometry alterations in acromegaly: Quantitative insights from Scheimpflug imaging and hormonal correlation.
Observational study in Indian journal of 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
purposeThis study aimed to evaluate changes in lenticular structures using the Pentacam HR in patients with acromegaly.
designProspective observational study.
methodsA total of 40 patients with acromegaly and 40 healthy volunteers were included in this prospective observational study. For anterior segment evaluation, lens densitometry values were analyzed in designated regions using the Pentacam HR Scheimpflug imaging system. The average values were calculated from predefined three-dimensional zones (Zone 1: 2.0 mm, Zone 2: 4.0 mm, and Zone 3: 6.0 mm), with the center of the pupil as the reference point.
resultsLens densitometry values in Zone 1, Zone 2, and Zone 3 were significantly higher in the acromegaly group compared to the control group ( P < 0.05 for each). Both maximum and mean lens densitometry values were also significantly elevated in the acromegaly group ( P = 0.046 and P = 0.041, respectively). A moderate but significant positive correlation was found between growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels and the lens densitometry values in all three zones ( P < 0.05 for each).
conclusionLens densitometry was significantly higher in acromegaly patients than in healthy controls, and these values were positively correlated with IGF-1 and GH levels.
