Impact of habitual swimming on the success of lacrimal surgery.
Article in Japanese journal of ophthalmology, 2021. 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
purposeTo elucidate how factors associated with swimming affect the lacrimal ducts of swimmers. STUDY
designProspective, interventional cohort study,
methodsFive hundred seventy four consecutive epiphora patients were surveyed via a questionnaire regarding details of their swimming-pool usage; i.e., frequency, swim-goggles' wear, and type of pool activity (i.e., swimming vs. waist-depth walking). In this cohort, all the swimmers over 20 years old with anatomical lacrimal duct obstruction underwent surgical reconstruction. The surgical success rates at 12-months postoperative were compared using multivariable logistic regression analyses between swimmer/non-swimmer patients, those with a history of high/low frequency of pool usage, and those with high/low amount of conjunctival contact with the swimming-pool water.
resultsOf the patients with anatomical lacrimal duct obstruction, 6.4% were habitual swimmers; nasolacrimal duct obstruction was more common in the swimmers than in the non-swimmers' controls (89.1%/66.7%, P = 0.025). The success rate of lacrimal surgery for the swimmers with anatomical nasolacrimal duct obstruction was lower (60.6%) than of the non-swimmers (83.3%, P = 0.048). A receiver operating characteristic curve analysis of the frequency for the prediction of surgical failure showed that the threshold was 4 days/week. The success rate was statistically lower (26.7%) in the high-frequency swimmers compared to the low-frequency swimmers (88.9%, P = 0.037). However, no statistical difference in the high/low ocular surface contact to the swimming-pool water was observed (71.4%/57.7%, P = 0.56).
conclusionHabitual swimmers have a high risk of nasolacrimal-duct damage retrogradely from the nasal cavity that lowers lacrimal surgery's success rate.
