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: Upper eyelid blepharoplasty, a corrective procedure for dermatochalasis, may transiently affect eyelid function and tear film stability. This study assessed the effect of upper eyelid blepharoplasty, subjectively through questionnaires, and objectively through tear film stability and production. Methods: This non-randomized, prospective, interventional study consecutively recruited the right eyes of patients with dermatochalasis who underwent bilateral upper eyelid blepharoplasty at a tertiary center. Preoperative assessments included a standardized ophthalmic examination, ocular surface disease index (OSDI) questionnaire, Schirmer's test I, tear break-up time (TBUT) test, and anterior segment optical coherence tomography (AS-OCT) to measure tear meniscus height (TMH) and tear meniscus area (TMA). Postoperative evaluations were conducted at 1, 3, and 6 months. At the final follow-up, scar quality and patient satisfaction were assessed using the Patient and Observer Scar Assessment Scale. Results: Fifty eyes of 50 patients with a mean (standard deviation) age of 47.1 (1.6) years were included. Statistically significant postoperative changes were observed in the OSDI score, Schirmer's test value, TBUT, and TMH at the 6-month follow-up (all P < 0.001). These parameters initially worsened at 1 month and then improved significantly at 3 and 6 months, returning to or surpassing baseline levels. TMA showed a transient postoperative decline, with full recovery at 6 months. Exceptionally strong positive correlations were found between TMH or TMA and TBUT or the Schirmer's test value at most follow-up visits (all Conclusions: We observed significant yet transient changes in tear film parameters and subjective assessments following upper eyelid blepharoplasty. A strong correlation was observed between AS-OCT measurements and parameters of tear film stability and production. High patient satisfaction and favorable cosmetic outcomes, with no visible scarring, further support the safety and tolerability of this procedure. Further studies with larger cohorts, longer follow-up periods, and comparative designs are warranted to validate these findings and further explore the long-term effects on ocular surface health and patient-reported outcomes.
