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
Cutaneous cancer is a rare entity accounting for less than 1% of all diagnosed cancers in India. In contrast to the West, squamous cell carcinoma is the commonest skin cancer in India, often affecting the scalp. However, due to their rarity, not much is known regarding their biological behavior and prognosis. The present study is a retrospective cohort study undertaken in a tertiary cancer centre on 19 consecutive cases of squamous cell carcinoma of the scalp over a period of 5 years. Patients with non-sqamous histology and those associated with xeroderma pigmentosum were excluded. Nineteen patients were evaluated with a mean age of 52.7 years. Majority presented with a swelling (11 patients; 57.9%) in the parieto-occipital region (13 patients; 68.4%). All patients underwent wide excision with or without excision of underlying bone or dura, depending on involvement. Only 4 (21%) required major reconstruction. On histopathology, 8 (42.1%) were poorly differentiated, while 3 (15.8%) had presence of perineural invasion (PNI). The mean duration of follow-up was 38.14 months. Three of the 4 (75%) and 2 of 3 (66.67%) patients with poorly differentiated histology and PNI respectively developed recurrence, while only 1 of the 6 (16.67%) with close or positive base margin developed recurrence. Hence, to conclude, poorly differentiated histology and PNI are poor prognostic indicators, while in the event the mucoperiosteum is clinically uninvolved, the underlying bone may be preserved in select cases, even if the base margin is close.
