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
backgroundWith the widespread use of integrase strand transfer inhibitors (INSTIs) in the clinical setting, transmission of INSTIs-resistance mutations may increase. Data regarding transmitted drug resistance mutations (TDRM) to INSTIs in Chinese HIV patients are limited. The aim of this study was to summarize the INSTIs TDRM, including the frequency of protease inhibitors (PIs) and reverse transcriptase (RT) inhibitors (RTIs) mutations in treatment-naïve patients in Southeast China.
methodsHIV-1 positive patients were retrospectively selected between April 2018 and October 2020 from the Mengchao Hepatobiliary Hospital of Fujian Medical University, the largest designated HIV/AIDS care hospital in Southeast China. Individuals who were antiretroviral therapy-naïve and received antiretroviral drug resistance testing at baseline were included. Clinical data including demographic data, CD4 counts, HIV-RNA loads, and drug resistance mutations were collected.
resultsA total of 147 patients were enrolled. INSTIs TDRM was rare, with only one primary integrase mutation E138K observed in one sample and one secondary mutation E157Q detected in another sample. The overall prevalence of INSTIs TDRM was 1.36%. A substantial proportion of patients harbored common INSTIs-associated polymorphic variants. Two samples harbored the T215S, M184V and K70E mutations related to nucleoside RTIs (NRTIs). Twelve patients carried nonnucleoside RTIs (NNRTIs)-resistance mutations. Two individuals harbored PIs-resistance mutations: Q58E in one patient and M46I, I54V, V82A, L10F, and Q58E mutations in another patient. The total TDRM rate for RTIs and PIs was 10.20% (15/147), but only 0.68% (1/147) was according to the WHO recommendations on TDRM.
conclusionThe rate of INSTIs TDRM was low among therapy-naïve HIV patients in Southeast China. INSTIs as a first-line regimen are suitable for untreated HIV-1 patients in Southeast China. But special attention must be still paid to INSTIs TDRM in clinical practice.
