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 light discomfort thresholds in patients with senile cataract versus pseudophakic subjects.
methodsIn this cross-sectional, multicenter, controlled study light discomfort thresholds were measured in both eyes of patients with senile cataract and in sex- and age-matched pseudophakic subjects using the Lumiz 100 device (Essilor International, Paris, France) under three different lighting conditions: continuous warm, continuous cold and flashing warm. For continuous increase, light starts at 25 lx for 5 s and increases every second by 20%; for discontinuous increases, light starts at 10 lx for 5 s followed by increases to 25 lx for half a second and then decreases back to 10 lx for 2 s, before a 44% increase from the previous flash using warm light. Age, gender, pupil diameter, self-reported light sensitivity, iris color, eyeglass use, visual acuity, lens status and cataract grade were analyzed and correlated with light discomfort thresholds.
resultsA total of 48 participants (28 men, 20 women; mean age 72.92 ± 9.05 years) were included. Patients with senile cataract exhibited statistically significant lower discomfort thresholds for all measurements compared to pseudophakic subjects (respectively, 3.39 ± 0.66 log10[lux] vs. 3.81 ± 0.46 [p = 0.014] for continuous warm; 3.44 ± 0.64 vs. 3.82 ± 0.42 [p = 0.025] for continuous cold; 3.14 ± 0.59 vs. 3.81 ± 0.31 [p < 0.001] for flashing warm). Apart for lens status, no other variables influenced light discomfort thresholds.
conclusionThe Lumiz 100 enabled the evaluation of light discomfort thresholds in patients with different lens status, highlighting a higher light sensitivity in patients with senile cataract compared to pseudophakic subjects under all lighting conditions.
