Scheduling Appointments for Postvasectomy Semen Analysis Has No Impact on Compliance.
Article in European urology open science, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundA postvasectomy semen analysis (PVSA) is recommended 8-16 wk after vasectomy to ensure azoospermia. Patient compliance with submitting a semen sample for PVSA has historically been low. To increase patient compliance, a policy change was made to schedule patients for PVSA appointments instead of a previous "drop-in" option.
objectiveTo compare patient compliance for PVSA when scheduling appointments as opposed to a "drop-in" appointment 8-16 wk after the procedure. DESIGN SETTING AND
participantsEthical approval was obtained to retrospectively evaluate patients undergoing vasectomy. A total of 400 patients were evaluated, 200 consecutive patients before and 200 after the policy change. Patients were excluded from analysis if they had other surgeries at the same time of vasectomy or if the vasectomy was a repeat procedure. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Percent of patients attending PVSA and time to PVSA were assessed. Nominal data were compared using chi-square analysis and interval data were compared using Student unpaired RESULTS AND LIMITATIONS: Thirteen patients were excluded from analysis: six before and seven after the policy change. Compliance rates were similar before and after the policy change (144/194 [74%] and 154/193 [80%],
conclusionsScheduling appointments for PVSA has no impact on compliance rates or the time between vasectomy and semen analysis when compared with "drop-in" appointments. PATIENT SUMMARY: Sterility after a vasectomy is guaranteed by delivering a semen sample. Many men do not deliver this sample, and sterility cannot be guaranteed. This study found that scheduling appointments did not increase the number of men who delivered a semen sample compared with "drop-in" appointments.
