Safety and efficacy of Vectored thermal pulsation, Intense pulsed light, and Eyelid Warm compress therapies (VIEW) for meibomian gland dysfunction: Study design and baseline characteristics of a randomized controlled trial.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundMeibomian gland dysfunction (MGD) is one of the most prevalent chronic eye diseases, characterized by meibomian gland obstruction and abnormal meibum secretion both in quantity and quality.
objectiveTo assess the efficacy and safety of vectored thermal pulsation (VTP), intense pulsed light plus meibomian gland expression (IPL + MGX), and eyelid warm compress (EW).
methodsThis is a 3-arm, assessor-masked, randomized controlled trial. 360 symptomatic mild to moderate MGD subjects would be recruited and randomized into 3 intervention groups. Subjects from Group-A, Group-B, and Group-C would be treated with one-session VTP (at baseline), four-session IPL + MGX (at baseline, month-1, month-2, and month-3 visits), and twice-daily EW for 15 months, respectively. All subjects would be prescribed topical artificial tears (Hypromellose, 0.3% w/v) to be used as frequently as needed from wash-out (1 month before baseline) to endpoint (month-15 visit). Subjects would be assessed 9 times throughout a total of 16-month study period. Five self-administered questionnaires would be collected each time in random order. Masked observers would conduct examinations using slit-lamp biomicroscopy, LipiView® II, and Keratograph 5M machines. The eye with worse MGD would be selected and analyzed as the study eye. Tear film break-up time (TFBUT) at month-6 and month-15 visits are the primary outcomes.
results374 subjects were enrolled and randomized into three groups, and 372 subjects (aged 54.4 ± 14.7 years) were finally analyzed. The mean of TFBUT time at baseline was 3.1 ± 1.7 seconds.
conclusionThis is the first head-to-head comparison of three physical treatments for mild to moderate MGD on their therapeutic efficacy, safety, longevity and compliance in a randomized controlled trial setting.
