Comparison of efficacy of trehalose-based eye drops versus topical 0.1% Hyaluronic Acid for management of clinically significant dry eye using non-invasive investigational modalities.
Trial report in International ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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 efficacy of trehalose-HA eye drops versus 0.1% hyaluronic acid for the treatment of dry eye.
methodsThis prospective, comparative, contralateral eye study included sixty eligible patients (mean age 44.13 ± 14.53 years). Patients having a SPEED questionnaire score of 16 or above, objective scatter index (OSI) > 1 and non-invasive tear break up time (NIBUT) of 10 s or less were included in the study. Eyes were randomized to receive 0.1% hyaluronic acid (HA) in one eye and trehalose-HA eye drops in the contralateral eye. At baseline, 1- and 3-month follow-ups, OSI, NIBUT, MG loss, tear meniscus height (TMH) and tear film osmolarity (TFO) were evaluated using non-invasive modalities
resultsThere was a statistically significant improvement in NIBUT, TMH, OSI, SPEED questionnaire score in the trehalose-HA compared to the 0.1% HA group at both 1- and 3-month visits (p < 0.05). In both the study groups, compared to the baseline, the mean values of TFO, MG loss, OSI and SPEED questionnaire score significantly reduced at 3 months (p < 0.05). The mean values of NIBUT and tear meniscus height on the other hand showed a significant increase compared to the baseline values (p < 0.05). Both drugs were well tolerated by the study participants without any significant ocular side effects.
conclusionTrehalose-HA was found to be more effective than 0.1% HA eye drops in the management of symptomatic dry eye, as shown by significant reduction in NIBUT, TMH and OSI, when evaluated using non-invasive modalities of dry eye evaluation.
