1 · What the graph read from it

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.

2 · The registry

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

backgroundThis study aimed to obtain the first evidence-based microbiological confirmation of the efficacy and an assessment of the local tolerability of a combination of an ocular antibiotic and a non-steroidal anti-inflammatory drug in treating moderate-to-severe acute bacterial conjunctivitis (ABC).

methodsThis was a phase II, randomized, parallel-group, masked-assessor, multicentre study to assess the non-inferiority of levofloxacin plus ketorolac eye drops versus levofloxacin eye drops alone in microbiological eradication (protocol number: LEVOKETO_02-2020). Treatment lasted 5 days. Non-inferiority was demonstrated if the lower bound of the two-sided 95% confidence interval (CI) of the difference was > -0.15. The study randomized 252 patients enrolled in 20 centers (Italy and Russia). The primary endpoint was the proportion of patients with microbiological eradication of levofloxacin-susceptible bacteria. Secondary endpoints included microbiological and clinical outcomes. This study is registered with EudraCT number 2020-005263-31.

resultsAt the final visit, 100% of patients in the test arm had eradicated levofloxacin-susceptible pathogens, versus 92.59% in the control arm (difference = 0.0741; 95% CI: 0.0042-0.1439). In the Per Protocol population, the levofloxacin-ketorolac eye drops combination proved to be superior (P < 0.0001) to levofloxacin eye drops alone in bacterial eradication during treatment of ABC with moderate-to-severe signs in adults despite being administered with a simplified dosing regimen. Local tolerability was similar between arms (p = 0.7666).

conclusionsThe levofloxacin-ketorolac combination was effective in bacterial eradication and well-tolerated in adults with moderate-to-severe ABC. These results suggest a possible positive levofloxacin-ketorolac interaction warranting further investigation in a phase III study.
