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
backgroundTranscanalicular lacrimal duct surgery has become more important over the past two decades.
objectivesThe aim of the study was to prove the prognostic value of postoperative lacrimal syringing and the testing of spontaneous drainage of lacrimal fluid immediately after tube removal.
methodsA total of 110 cases with postoperative lacrimal syringing and 183 cases with verification of the postoperative lacrimal fluid drainage performed between January 2001 and August 2008 were retrospectively evaluated. The indication for postoperative diagnostics was set by the investigator. The prognostic value of these two procedures was determined by using prognostic parameters (positive predictive value, PPV; negative predictive value, NPV) and analyzing recurrence nonexistence via Cox regression and Kaplan-Meier estimator. The observation period was limited to 12 months. Predominantly, recurrence was defined on the patient's satisfaction and absence of symptoms, which was determined with the help of a questionnaire.
resultsPostoperative verification of the lacrimal syringing is a suitable instrument to estimate surgical success within the first year after lacrimal surgery with a PPV of 92.31%. Testing of the spontaneous drainage of lacrimal fluid after tube removal reached a PPV of 63.33%.
conclusionThe proven prognostic value shows that syringing of the lacrimal duct and verification of spontaneous drainage should be integrated into postoperative care in a standardized manner. Hereby, early information for the patient about the expected result of the surgical procedure is enabled.
