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
Background: This study aimed to determine whether there is a significant difference in the efficacy of transconjunctival tucking of the Müller muscle and levator aponeurosis in patients with involutional blepharoptosis who tested positive or negative on the phenylephrine test. Methods: The analysis involved 64 eyes of 42 patients with levator muscle function of the upper eyelid of 8 mm or more and a margin reflex distance 1 (MRD-1) of less than 2 mm. Patients who tested positive and negative for 5% phenylephrine were allocated to group A (41 eyes of 26 patients) and group B (23 eyes of 16 patients), respectively. The efficacy of surgery (ΔMRD-1) was compared by subtracting preoperative MRD-1 from postoperative MRD-1. Multiple comparison tests were performed to evaluate changes in MRD-1 and ΔMRD-1 every 3 months from 3 to 12 months after transconjunctival tucking of the Müller muscle and levator aponeurosis. Results: Regarding the mean ΔMRD-1 values at 3, 6, and 12 months postoperatively, the values at 6 and 12 months were significantly lower in group A than in group B, with 2.31, 1.98, and 1.81 mm, respectively, in group A and 2.73, 2.71, and 2.50 mm, in group B ( Conclusions: The efficacy of transconjunctival tucking of the Müller muscle and levator aponeurosis was greater in group B than in group A, and the results were more stable. This is an interesting finding when considering the successful mechanism in the present surgical method.
