Indwelling urinary catheterization was unnecessary in non-drainage total knee arthroplasty: a randomized controlled trial.
Trial report in Archives of orthopaedic and trauma surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03341819 (Comparative Study Between Retained and Non-retained Urinary Catheter in Total Knee Arthorplasty With Epidural Anesthesia), which is not on this map.

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.

Abstract
purposeTo investigate whether catheterization remains necessary in non-drainage total knee arthroplasty (TKA) using combined spinal epidural anesthesia (CSEA) with a short-acting opioid by comparing (1) incidences of postoperative urinary retention (POUR), and (2) postoperative clinical outcomes between retained urinary catheter (UC) and non-retained urinary catheter (non-UC) groups.
methodsA total of 230 patients underwent non-drainage TKA using CSEA with fentanyl were randomized into UC and non-UC groups (115 patients each, 115 knees each). Incidences of POUR, clinical outcomes (intraoperative intravenous fluid, operative time, whole blood loss, urinary tract infection (UTI), and length of stay) were evaluated after the operation, while range of motion (ROM) and Knee society score (KSS) were evaluated 3- and 6-month postoperatively.
resultsIncidences of POUR and other perioperative and postoperative clinical outcomes between the two groups were not significantly different. ROM and KSS at 3- and 6-month postoperatively revealed no significant differences between the groups.
conclusionGiven no significant difference in POUR incidence, clinical outcomes and knee scores and functions, catheterization in non-drainage TKA under CSEA with a short-acting opioid might not be necessary. CLINICAL TRIALS: Clinical Trials gov (NCT03341819) (11/09/2017).
