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
Operation theatre (OT) time utilisation rates can be improved with an assessment of the procedure time that will result in effective scheduling of cases. Our study is the first of its kind to audit the amount of OT time required for a particular surgery in lip and oral cavity cancers, depending on the various components of this complex procedure. This prospective cross-sectional study, based on an operative room database of 323 OT sessions, was conducted in the Department of Surgical Oncology at a tertiary care centre on lip and oral cancer patients from January 1st, 2019 to December 31st, 2020. Various components of the surgery, like the primary site, operating surgeon, type of neck dissection, bone resection, and reconstructive procedure, were noted. The time of entry and exit of the patient from the OT was noted. Operative time and OT time utilisation rates were calculated. SPSS 21.0 statistical tool; Students 'T', ANOVA and Games-Howell tests were applied. In 323 OT sessions, while 303 surgeries were done for primary cases (93.8%), the remaining 20 cases were for recurrent cases (6.2%). Buccal mucosa and the floor of the mouth were the most and least common sites, respectively. The mean OT time was 212.42 ± 73.83 min, the maximum being the primary at alveolus. The mean OT late start time was 70.03 ± 23.41 min and the mean OT runover time was 37.62 ± 43.53 min. The mean time varied significantly with the type of neck dissection, bone resection, and reconstructive surgery done and the operating surgeon. The mean OT time was highest for free flap reconstructive surgery (328.71 ± 62.02 min), but it didn't vary with its type. Considering only the lip and oral cancer surgeries, the OT time utilisation rate was 57.1%. Assessment and quantification of the operative duration of lip and oral cancer surgeries will help in accurate prediction of surgical duration, better OT list planning, and thus improved OT time utilisation rate. Our research not only provides data on the historical mean of procedures, but it may also encourage other centres to adopt our quantitative approach to OT scheduling.
