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 AND
objectiveThe objectives of this study were to assess the yield of multiplex PCR testing in LRTI and its utility in antimicrobial streamlining. Establishing the microbial aetiology is of paramount importance for tailored antimicrobial therapy in lower respiratory tract infections (LRTI). Multiplex PCR panels (FilmArray Pneumonia Plus Panel [FAPP]) have been shown to provide better diagnostic yield in LRTI.
methodsA total of 103 patients hospitalized with LRTI were enrolled. The culture isolates, their sensitivity pattern, and antimicrobial resistance were noted. Time taken for availability of FAPP results as well as culture positivity was documented. Antibiotic modification made based on identification of the pathogens along with their resistant gene patterns from appropriate samples and time taken to reach that decision was noted and compared between conventional culture and FAPP.
resultsFAPP detected at least one pathogen in (92/103) of tested specimens. Conventional culture detected at least one pathogen in 36 (34.9%) cases only. The mean duration of antibiotic therapy in FAPP-positive cases was 4.89 ± 1.84 days versus 7.2 ± 3.83 days in cases where FAPP was negative ( P value of 0.019). Similarly, the duration of hospital stay in FAPP-positive cases versus -negative cases was 5.136 ± 1.73 days versus 7.6 ± 3.36 days, respectively ( P value 0.007). Mean turnaround time (TAT) for the FAPP was strikingly low with FAPP. Antimicrobial modification guided by FAPP was achieved in 83 out of 103 patients (80.6%), substantially higher than with conventional culture.
conclusionIn hospitalized patients with LRTI, FAPP provided better diagnostic sensitivity, better detection of resistance, faster TAT, higher potential for antimicrobial modification, lesser days of antibiotic use, and shorter hospital stay compared to culture.
