Factors affecting pain in patients undergoing bilateral cataract surgery.
Article in International ophthalmology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers.
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
purposeTo compare the perceived pain and estimated operative duration among patients undergoing bilateral cataract surgery and to demonstrate correlations with the surgical interval and the demographic and medical characteristics of the patients.
methodsA total of 466 patients with cataract who underwent ocular surgery were included. The patients estimated the perceived operative duration and pain they felt during the operation at two times, immediately after surgery and on the first postoperative day; pain was scored using a visual analog scale ranging from 0 (no pain) to 10 (unbearable pain). Patients undergoing bilateral surgeries were divided into four subgroups based on the interval between the two operations (1, 2, 4, or 6 weeks). The perceived pain score and the estimated operative duration were the primary outcomes.
resultsThe pain scores were higher for the second surgery than for the first surgery both immediately after surgery (P = 0.043) and on the first postoperative day (P = 0.002). The estimated operative duration was longer for the second surgery (P = 0.001). Only patients who underwent the second surgery at an interval of 2 weeks perceived more pain both immediately and 1 day postoperatively (P = 0.002, P = 0.022) and a longer operative duration (P < 0.001). Gender, age, and education level might also influence the pain score.
conclusionsFemale patients, patients with a younger age, and patients with higher education level are likely to report more pain. Patients who require bilateral cataract surgery should not undergo the second surgery before an interval of 2 weeks.
