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
Objective: To determine whether consuming Kentucky Fried Chicken (KFC) before a surgical on-call shift increases operative workload, as is widely believed among Thai healthcare workers. Design: Three-arm randomized controlled trial. Setting: General surgery department, Phatthalung Hospital, July 2023-June 2024. Participants: Five general surgeons contributing 345 duty shifts; 313 shifts formed the primary analysis (Control 107, KFC 101, Five Star 105) after excluding 32 resident-present shifts. Interventions: Shifts were randomly allocated (permuted blocks, allocation concealment) to Control (no intervention), KFC, or Five Star brand fried chicken. Main outcome measures: Primary outcomes: total workload (cases per shift), number of operations, and number of consultations. Secondary outcomes: estimated blood loss and operative time. Exploratory outcome: surgeon belief score change before and after trial completion. Results: No primary outcome differed significantly between arms. Median total workload was 14 (IQR 11-17), 16 (IQR 12-19), and 14 (IQR 11-17) cases per shift for Control, KFC, and Five Star arms, respectively ( Conclusions: KFC consumption does not increase surgical on-call workload. The significant decline in surgeon belief scores suggests that structured self-experimentation may effectively challenge culturally embedded superstitions in clinical practice.
