The Effectiveness of Cefazolin Prophylaxis on Infection after Transureteral Lithotripsy: A Randomized Clinical Trial.
Trial report in Ethiopian journal of health sciences, 2023. 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
Background: Transureteral lithotripsy (TUL) is one of the most common surgeries in urology, and many TUL procedures have been performed with antibiotics prophylaxis. The present study investigates the effect of antibiotic prophylaxis on the rate of urinary infection after TUL. Methods: This double-blind, randomized clinical trial was conducted on 158 patients with ureteral stones, with 79 in each group: the prophylaxis cefazolin group (Group A) and the placebo group (Group B). The patients were referred to Imam Hassan Hospital in Bojnurd, Iran. The standard technique of TUL operation was performed using a pneumatic lithoclast and a semirigid 9/8/Fr ureteroscope. The bacterial isolates were identified through growth on EMB agar and blood agar. Antimicrobial sensitivity testing (AST) was carried out by disc diffusion technique. Results: According to our results, 157 patients were eligible for analysis; 79 patients in Group A and 78 patients in Group B. Flank pain and urinary complaints were the most common symptoms. Our findings indicate that cefazolin prophylaxis did not show any significant differences in preventing postoperative infection between the two groups. E. coli accounted for eight 10.1% (8/79) Group A and 9% (7/78) in Group B, respectively. The results of AST for the 15 E. coli strains revealed a high rate of antibiotic resistance against ampicillin (73.3%). Conclusion: Our findings indicate that prophylactic antibiotic administration does not demonstrate effectiveness in reducing the infection rate following TUL surgery. Antibiotic prophylaxis is not recommended considering the potential adverse effects, cost implications, risk of antibiotic resistance, and lack of efficacy.
