Digital analysis of unilateral ptosis repair: external levator advancement vs. Müller's muscle conjunctival resection.
Review in Arquivos brasileiros de oftalmologia, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07003308 (Comparative Study of the Efficacy of Anterior Versus Posterior White Line Advancement Technique in the Correction of Primary Aponeurotic Ptosis), which is not on this map.

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.

Abstract
purposeEvaluation of lid contour and marginal peak point changes to compare outcomes of external levator advancement and Miiller's muscle conjunctival resection surgery in unilateral ptosis.
methodsWe reviewed the charts of unilateral ptosis patients who underwent external levator advancement or Miiller's muscle conjunctival resection. Eyelid contour analysis was conducted on preoperative and 6-month postoperative digital images. This was performed with the multiple margin reflex distances technique, measuring the vertical distance from a line intersecting the center of the pupil to the eyelid margin at 10 positions at 2 mm intervals. The marginal peak point changes were analyzed digitally using the coordinates of the peak point according to the pupil center. Each position's mean distance was compared preoperatively, postoperatively, and with the fellow eyelid.
resultsSixteen patients underwent external levator advancement and 16 patients had Miiller's muscle conjunctival resection. The mean margin reflex distance was improved by both techniques (1.46 vs. 2.43 mm and 1.12 vs. 2.25 mm, p=0.008 and p=0.0001 respectively) and approached that of the fellow eyelid (2.43 vs. 2.88 and 2.25 vs. 2.58 mm, p=0.23 and p=0.19, respectively). However, statistically significant lid margin elevation was limited to between the N6 and T6 points in the external levator advancement group. Whereas, significant elevation was achieved along the whole lid margin in the Miiller's muscle conjunctival resection group. The marginal peak point was shifted slightly laterally in the external levator advancement group (p=0.11).
conclusionsBoth techniques provide effective lid elevation, however, the external levator advancement's effect lessens toward the canthi while Müller's muscle conjunctival resection provides more uniform elevation across the lid margin. The margin reflex distance alone is not sufficient to reflect contour changes.
